Question 1
Many fishes native to the Amazon basin are important aquarium fish. But one in species in particular outnumbers all the others in terms of numbers of specimens exported form the Amazon region each year. Which species is it? Neale Monks 22:15, 4 April 2007 (UTC)
 * My guess is neon tetra. --Melanochromis 00:46, 5 April 2007 (UTC)
 * Guppy?. Jnpet 01:32, 5 April 2007 (UTC)
 * Probably wrong, but Freshwater angelfish? MiltonT 05:14, 5 April 2007 (UTC)
 * No, no, and no. A clue? Don't think about where the fish _first_ came from, but where they come from now... Neale Monks 12:05, 5 April 2007 (UTC)
 * A shot in the dark here the Discus Fish? Bass fishing physicist 13:10, 5 April 2007 (UTC)
 * Nope. Read the whole question, not just the first sentence! Neale Monks 13:20, 5 April 2007 (UTC)
 * Cardinal tetra? This is a tough one. MiltonT 19:44, 5 April 2007 (UTC)
 * Suckermouth catfish? Maybe? Bass fishing physicist 19:53, 5 April 2007 (UTC)
 * MiltonT gets it! It's the cardinal tetra, which accounts for (apparently) 80% of all the fishes exported from the Amazon. All the other common South American fish -- angels, discus, neons, Corydoras, etc. -- are farmed. The cardinal is not (yet) widely farmed. Neale Monks 20:28, 5 April 2007 (UTC)

Question 2
See this rather curious fish. What fish is it? MiltonT 05:52, 6 April 2007 (UTC)
 * Great picture. Grunt sculpin (Rhamphocottus richardsonii)? --Melanochromis 07:03, 6 April 2007 (UTC)
 * That's it all right. Point to Melanochromis. MiltonT 16:39, 6 April 2007 (UTC)

Question 3
See another curious fish from Flickr. What fish is it? --Melanochromis 17:15, 6 April 2007 (UTC)
 * Looks like one of those Flowerhorn beasts, but I ain't no cichlid expert. MiltonT 18:38, 6 April 2007 (UTC)
 * Correct. One point to MiltonT. --Melanochromis 19:05, 6 April 2007 (UTC)

Question 4
This fish's attraction to urine will make you think twice before using the bathroom anywhere near the river. What is this fish? MiltonT 02:02, 7 April 2007 (UTC)


 * Candirú (Vandellia cirrhosa)? Bass fishing physicist 08:49, 7 April 2007 (UTC)
 * That's the fish all right. One point to Bass fishing physicist. MiltonT 15:45, 7 April 2007 (UTC)

Question 5
This eel is used in Lyme Regis for a, locally, famous event. What is it? Bass fishing physicist 00:39, 8 April 2007 (UTC)
 * Is it conger eel? Particularly Conger conger according to a Practical Fishkeeping article. --Melanochromis 01:21, 8 April 2007 (UTC)
 * Correct. The conger eel is used in the aptly named Conger cuddling event. Thats a point to Melanchromis. Bass fishing physicist 08:04, 8 April 2007 (UTC)

Question 6
I kind of ran out of questions at the moment. So I'm going to ask people to do a simple task instead if you don't mind. Find a fish article that doesn't have a picture, add to that article a nice picture with proper licenses (or a public domain image). Then put a link here to show me which article you have done. --Melanochromis 18:33, 8 April 2007 (UTC)
 * I did Yellowmargin triggerfish and Nemateleotris magnifica before you asked this, does that count? :p If not, I added a picture to Amblyeleotris. MiltonT 19:18, 8 April 2007 (UTC)
 * That's a great job. One more point to MiltonT. --Melanochromis 20:19, 8 April 2007 (UTC)

Question 7
This blue and orange non-Chaetodontid fish feeds almost exclusively on Acropora corals, leading to its quick demise in captivity. What fish is this? MiltonT 20:27, 8 April 2007 (UTC)
 * Orange spotted filefish (Oxymonacanthus longirostris)? Bass fishing physicist 22:30, 8 April 2007 (UTC)
 * Correct. Hope that wasn't too easy. ;) MiltonT 22:55, 8 April 2007 (UTC)

Question 8
The deceptive name of this fish supposedly comes from an English corruption of the method of transportation used to distribute it from present day Mumbai. Bass fishing physicist 23:38, 8 April 2007 (UTC)
 * This is a good question. Bombay duck? --Melanochromis 00:49, 9 April 2007 (UTC)
 * That's the one. Bass fishing physicist 00:55, 9 April 2007 (UTC)

Question 9
Have a loot at this picture. No, the question isn't whether the man was wearing any underwear. I just want to know what fish that is. --Melanochromis 01:30, 9 April 2007 (UTC)
 * Wels catfish? MiltonT 01:46, 9 April 2007 (UTC)
 * Correct. --Melanochromis 02:58, 9 April 2007 (UTC)

Question 10
One common name of this fish is used because of its caudal fin, which appears to have writing on it as the fish changes from juvenile to adult forms. What fish is this? MiltonT 13:23, 9 April 2007 (UTC)
 * I'm not so sure but I'll guess that it is the yoyo loach. --Melanochromis 18:56, 9 April 2007 (UTC)
 * No, it's not the yoyo. The "writing" on the fish I am asking about appears on the caudal fin. MiltonT 16:50, 10 April 2007 (UTC)
 * Here's a hint: The writing on this fish's tail isn't in a Latin alphabet. MiltonT 13:01, 11 April 2007 (UTC)
 * Here's a hint: The other common name of this fish indicates the shapes that appears on the juvenile form of this fish. Well, half-shapes, anyway. MiltonT 04:07, 13 April 2007 (UTC)
 * Wild guess coming up. Could it be the Pomacanthus semicirculatus? Semicircle angelfish would be the common name in terms of shape, AKA Koran angelfish? Jnpet 06:53, 13 April 2007 (UTC)
 * Correct. In the juvenile of this fish, there are semicircular bands, which is different from the juveniles of some other, similarly colored angelfish juveniles. In transforming to an adult, squiggles appear on the caudal fin that appear Arabic, giving the fish the name Koran Angelfish. Point to Jnpet. MiltonT 13:33, 13 April 2007 (UTC)
 * Wow. That was good. I could never have answered this question :( --Melanochromis 17:58, 13 April 2007 (UTC)

Question 11
In Sweden, there is a dish served made of a particular fish species. It is likened to rotten fish and smells accordingly. Two part question. Name the dish and the fish. (Please be specific). Jnpet 11:27, 14 April 2007 (UTC)
 * The dish is Surströmming and the fish is Baltic herring. I looked it up and a BBC article says some airlines banned this dish and it got the Swedes really angry :-) --Melanochromis 12:37, 14 April 2007 (UTC)
 * That's it! Hope it wasn't too easy. Another point to Melanochromis. Jnpet 14:02, 14 April 2007 (UTC)

Question 12
This fish is said to be "bloodless" but it actually has a "colorless" blood. What is this fish (0.5 point)? and why is its blood colorless (0.5 point)? --Melanochromis 17:56, 14 April 2007 (UTC)
 * Channichthyidae (icefish). They possess no haemoglobin, their bodies function on oxygen dissolved in the bloodstream absorbed from outside. Bass fishing physicist 18:40, 14 April 2007 (UTC)
 * Correct. One point to Bass fishing physicist. --Melanochromis 21:15, 14 April 2007 (UTC)

Question 13
The trunk belonging to one of the Twelve Apostles lends it's name to this fish. Bass fishing physicist 23:05, 14 April 2007 (UTC)
 * A hint, pachyderm. Bass fishing physicist 16:16, 15 April 2007 (UTC)
 * Hmm Peters' elephantnose fish? --Melanochromis 18:03, 15 April 2007 (UTC)
 * Spot on. Another point to Melanochromis. Bass fishing physicist 18:17, 15 April 2007 (UTC)

Question 14
What are these numbers? --Melanochromis 02:34, 16 April 2007 (UTC)
 * Goldfish: 0
 * Tench: 1
 * Iridescent shark: 2
 * Zebrafish: 2
 * Common carp: 2
 * Skunk loach: 3
 * Clown loach: 4
 * Hint: It's something visible. You can easily count it although for some fish you might have to look closely. --Melanochromis 06:27, 17 April 2007 (UTC)
 * Another wild guess. The number of barbels? Jnpet 07:40, 17 April 2007 (UTC)
 * Jnpet's guess is very very close, but not exactly the correct answer. These numbers are not exactly "numbers of barbels" because a tench doesn't have one barbel, and a common carp doesn't have just two barbels. Look at this koi (common carp) picture. [[Image:Koi head closeup.jpg|20px]] How are barbels counted?
 * In pairs. Bass fishing physicist 21:41, 17 April 2007 (UTC)
 * Yep. The correct answer is that these numbers are "pairs of barbels". I'm not sure who should get the point. Jnpet got the idea first. But Bass fishing physicist refined it. If you don't mind, I'll split the point and you each get 0.5 point. Any of you two can post the next question. --Melanochromis 22:16, 17 April 2007 (UTC)

Question 15
Nice and easy this one. This righteye flounder sounds like it belongs in a mythical story, or perhaps Harry Potter :). Bass fishing physicist 15:48, 18 April 2007 (UTC)
 * Torbay sole, also known as the witch. MiltonT 17:07, 18 April 2007 (UTC)
 * Correct, one point to MiltonT. Bass fishing physicist 17:09, 18 April 2007 (UTC)

Question 16
Take a look at this flickr image. What is this fish? MiltonT 03:56, 19 April 2007 (UTC)
 * My guess is that it's a flying gurnard. If you want a species, I'd say it's a Dactylopterus volitans. The fact that this fish is found in Brazil matches the information from the image caption. --Melanochromis 04:45, 19 April 2007 (UTC)
 * Flying gurnard was all I wanted to hear. Point for Melanochromis. MiltonT 04:51, 19 April 2007 (UTC)

Question 17
According to some Chinese mythology, this fish can turn into dragons by completing a particular challenge. What is this fish (0.5 point)? And what is the challenge (0.5 point)? --Melanochromis 07:03, 19 April 2007 (UTC)
 * Could it be carp? And the challenge is to swim against torrents of water and clear a huge leap at the Dragon's gate in the Yangtze River. Jnpet 10:44, 19 April 2007 (UTC)
 * Correct! That would be one point to Jnpet. --Melanochromis 17:49, 19 April 2007 (UTC)

Question 18
This royalty is known as an amateur specialist of ichthyology and has published many papers and books on the subject. In 2005, a newly described fish was named in his honor. Who is this royal ichthyologist? (0.5 point) and what's the fish named after him (0.5 point)? --Jnpet 02:10, 20 April 2007 (UTC)


 * Emperor Akihito of Japan? There's a goby, Exyrias akihito, named after him. His son Prince Akishino is also a noted ichthyologist. --Melanochromis 03:35, 20 April 2007 (UTC)
 * That's the answer! Another point to Melanochromis! Jnpet 05:18, 20 April 2007 (UTC)

Question 19
Look at the main fish in this flickr picture. What is that fish? Hint: its tankmates can give you clues where this fish is from. --Melanochromis 07:57, 20 April 2007 (UTC)
 * My gut first guess is Leptobarbus hoevenii. MiltonT 16:53, 20 April 2007 (UTC)
 * Yes, it is the mad barb, Leptobarbus hoevenii. I thought this question was going to be really hard but you got it at first guess! Very good job. One point to MiltonT. --Melanochromis 19:49, 20 April 2007 (UTC)

Question 20
The Oarfish is also commonly known as the King of Herring. But it seems that the herring have another king as well. What is the fish? MiltonT 01:35, 21 April 2007 (UTC)
 * Chimaera monstrosa?, FishBase: . Bass fishing physicist 11:01, 21 April 2007 (UTC)
 * Correct, point to Bass fishing physicist. MiltonT 12:59, 23 April 2007 (UTC)

Question 21
In 2003 a new species of shark was discovered in the Gulf of California, the first new shark species to be discovered in the area for 34 years. What shark is this? Bass fishing physicist 15:36, 23 April 2007 (UTC)
 * Ah, Mustelus hacat. MiltonT 17:00, 23 April 2007 (UTC)
 * Correct, another point for MiltonT. Bass fishing physicist 17:27, 23 April 2007 (UTC)

Question 22
It is believed by some that the name of this fish comes from the sound it makes while it sucks shelled prey. MiltonT 18:19, 23 April 2007 (UTC)
 * Nurse shark? Some say it sounds like a nursing baby when it's sucking preys. --Melanochromis 21:51, 23 April 2007 (UTC)
 * Yup, that's right. Point for Melanochromis. MiltonT 03:31, 24 April 2007 (UTC)

Question 23
This fish is quite capable of living in both salt and freshwater. The marine ones however are well-armored while the freshwater lake counterparts aren't. According to a study, some oceanic well-armored fish were introduced into a freshwater lake in the 90s. The fish then evolved so rapidly that just about a decade later 90% of the fish lost their oceanic form and were no longer well-armored. What is this fish? --Melanochromis 21:04, 24 April 2007 (UTC)
 * Could it be Sturgeons? Jnpet 01:59, 25 April 2007 (UTC)
 * Nope. This fish is much much smaller than the sturgeon. --Melanochromis 02:11, 25 April 2007 (UTC)
 * The stickleback? Jnpet 02:21, 25 April 2007 (UTC)
 * You got it! It is the stickleback, specifically the Three-spined stickleback. One point to Jnpet. --Melanochromis 03:03, 25 April 2007 (UTC)

Question 24
This tiny species, (no longer than 2.4 cm), has a very effective camouflage. It is so effective, it was accidentally discovered in 1970 when its host was collected and placed in an aquarium. What species is this? For a .5 point bonus, also name the host. (Have taken the liberty of adding a .5 point bonus as I did not ask a new question for half the correct answer on question 14 above). --Jnpet 05:59, 25 April 2007 (UTC)
 * Ooh, that's the mysterious miniature pygmy seahorse of gorgonians. MiltonT 06:25, 25 April 2007 (UTC)
 * Yes! That's it! 1.5 points to MiltonT! --Jnpet 08:11, 25 April 2007 (UTC)

Question 25
This fish's bite has been responsible for subduing a submarine. What species is this? MiltonT 13:32, 25 April 2007 (UTC)
 * Cookiecutter shark? Its article says that "there was an incident in which a cookiecutter shark took a bite out of the rubber sonar dome of a US Navy submarine, causing damage to the housing, and forcing the submarine out of service until the rubber could be replaced." --Melanochromis 17:50, 25 April 2007 (UTC)
 * That's right. Point for Melanochromis. MiltonT 18:15, 25 April 2007 (UTC)

Question 26
Have a look at this YouTube clip. I can count 10 different kinds of fishes in this tank. Can you give me a list of these fishes? The first person who can list 10 or more fishes will get 1 point. To make it easier, you don't have to name the exact species of the fish (unless you want to). Genus is good enough. Good luck. --Melanochromis 23:51, 25 April 2007 (UTC)
 * Looks like we got a Silver arowana (Osteoglossum bicirrhosum), what appear to be Silver Dollars (Metynnis sp.), Lima shovelnose (Sorubim lima), an out-of-place goldfish (Carassias auratus), some sort of bichir (Polypterus sp.), a Green terror (Aequidens rivulatus), a Firemouth (Thorichthys meeki), a severum (Heros severus), a pike cichlid (Crenicichla sp.), and what could be a Midas or a Red Devil (Amphilophus sp.) since I don't know how to differentiate the two. I can't distinguish more than 10 species myself... MiltonT 02:22, 26 April 2007 (UTC)
 * Great job. One more point to you. PS. I saw the 11th fish in that tank. It's an oscar. --Melanochromis 03:03, 26 April 2007 (UTC)
 * I could've sworn I saw an Oscar for a moment, but didn't get a good look, hehe. MiltonT 03:06, 26 April 2007 (UTC)

Question 27
The males of this species of fish has spoon-like extensions of the gill cover that are used during courtship. What species is this? MiltonT 13:23, 26 April 2007 (UTC)
 * My guess is the longear sunfish (Lepomis megalotis). Two studies in 1997 and 2000 show that males "have longer opercular flaps than females, and females are known to prefer males with longer flaps, suggesting that these exaggerated structures serve as sexual ornaments." --Melanochromis 19:40, 26 April 2007 (UTC)
 * Good guess, good guess. However, the fish I'm talking about has much longer and skinnier extensions and are basically more oar-like. MiltonT 19:59, 26 April 2007 (UTC)
 * How about the Swordtail Characin (Corynopoma riisei)? "the male has paddle-shaped extensions of the operculum which can be extended perpendicular to its body and twitches and flutters due to movements of his body; the female follows and nips at these projections during courtship." --Melanochromis 20:18, 26 April 2007 (UTC)
 * That's right. With your score at 10 points, that means you win Tournament II. MiltonT 20:29, 26 April 2007 (UTC)
 * That was really fun and I learned a lot. Thanks MiltonT. I'll post the first question for Tournament III soon. --Melanochromis 20:34, 26 April 2007 (UTC)
