I think i just saw my zebra danio (male) eat a neon tetra. This could be its second, since I lost another a week ago, plus a small zebra danio has gone missing. Does anyone know if this is common behaviour for a zebra danio? If so I might need to kill it to save my other fish.¨

-> Zebrafish do commonly eat other fish who are dead or even dying, but I've never seen one attack a healthy fish. I think the temperature range stated in the article is wrong - zebrafish prefer a range of about 24-28C, as far as I know. 28 is about optimal; 18 is too low. —The preceding unsigned comment was added by 137.122.149.57 (talk • contribs) 12:16, 8 June 2006 (UTC-7)

This image claims these fish change color - has anyone observed that? Could information be added to the article? --70.112.222.14 19:39, 30 July 2006 (UTC)
 * Yes, they do (as do pretty much all fish), see chromatophore. I have added the image to the article. Rockpock  e  t  07:59, 23 February 2007 (UTC)

My danio laid eggs.What shold I do?

Suggest move to "zebrafish"
I suggest moving this page to zebrafish. Currently zebrafish is a disambiguation page with only two links: red lionfish and this page. Therefore I think most wikipedia users who search for "zebrafish" would be wanting this page, so we should send them here directly. I've put a disambig note at the top of this page which directs to the red lionfish page. I've temporarily moved the zebrafish disambig page to "zebrafish 2", but I still can't move this page to "zebrafish" because the old disambig page still exists as a redirect. I'm looking for an administrator who can help by deleting both the "zebrafish" and the "zebrafish 2" pages. I can then move this page and fix all the links over the weekend. Adrian J. Hunter 15:48, 21 December 2006 (UTC)
 * The red lionfish only lives in Australia, and I believe it is known by several other common names.
 * D. rerio is a both a popular aquarium fish worldwide and an important model organism. Even in academia, D. rerio seems to be mainly referred to as "zebrafish" (going by my own observations as an Australian genetics student).

Also WikiProject Fishes refers to Naming conventions (fauna) for article names, which states that when a common name exists, it should be used for the article title. Adrian J. Hunter 06:22, 22 December 2006 (UTC)

I have never heard of a Zebra Danio eating another or any other spiecies of fish. But I know they nip alot, well it least mine have not showed any signs of eating onother besides for tail nipping.

for such a biologically important fish and fun aquaruim pet, i'd like to see some basic natural history
of the little bugger. what it eats, how long it lives. where it lays its eggs. mating behavior? interactions with other critters in its environment...Wikiskimmer 06:47, 4 July 2007 (UTC)

Naming
Can someone explain why the fish is sometimes referred to as Brachydanio rerio, and why sometimes just Danio rerio? Can you add this to the page? Thanks MrPMonday (talk) 02:16, 14 May 2008 (UTC)

Only Danio rerio is officially valid. Other syn. are Brachydanio rerio or Cyprinus rerio.

Reference - ITIS - Brachydanio rerio or ITIS - Cyprinus rerio or ITIS - Danio rerio

Sometimes a fish is hard to id as it is often examined many years later and is preserved in a jar and has lost its colour. So taxonomists can and do accidentally id 3 different fish as 3 different species. The Cyprinidae family is bit of a mess I'm told. Fish are always getting reclassified.

Why do people use these other names? Maybe because of an old book or someone not asking a taxonomist?

--Quatermass (talk) 13:25, 6 January 2009 (UTC)

I added the explanation for the use of Brachydanio vs. Danio in the Taxonomy section of this article. It's a convential switch that has been made since the 1993 Zebrafish Meeting at the Cold Spring Harbor Laboratory.

Tytybaby620 (talk) 18:39, 15 July 2012 (UTC)

Since Kotellat (2013), this fish is better-classified as Brachydanio, due to morphological and molecular differences with D. dangila, the type species. Danionins with vertical bars and none to very short barbels are now best-classified as Celestichthys (i.e. C. margaritatus, C. erythromicron, etc), and those with small, slimmer bodies, longer barbels, and horizontal bars are Brachydanio (i.e. B. kyathit, B. rerio, etc). Only D. dangila remains in the Danio genus. I've lightly-edited the Taxonomy section to reflect this re-classification.

Should a section "model organism for pathogenesis" be added? Taken from http://www.ncbi.nlm.nih.gov/pubmed/18248169 with slight modification:
The successful zebrafish developmental model has now expanded to being used as a model for the analysis of host–pathogen interactions during infectious disease. Numerous pathogens have been demonstrated to infect zebrafish and new mechanisms of virulence, as well as host defense have been uncovered using this new model. Successful infection of zebrafish has been demonstrated using a variety of pathogens including the zoonotic fish pathogens Mycobacterium marinum, Edwardsiella tarda, Salmonella arizonae, Vibrio anguillarum, and Streptococcus iniae. Furthermore, infection of zebrafish has been successfully demonstrated with pathogens that are not known to infect fish such as Salmonella typhimurium, Bacillus subtillis, Escherichia coli, multiple species of Listeria, Streptococcus agalactiae (M.N. Neely and D.R. Runft, unpublished data) and Streptococcus pyogenes. Snakehead rhabdovirus, a virus that infects warm-water fish, was also used for zebrafish infection to analyze upregulation of multiple host proteins involved in the immune response. —Preceding unsigned comment added by ZebrafishPathogenesis (talk • contribs) 06:29, 9 June 2008 (UTC)

WT strains
can someone make my list of WT strains into columns or something? Im a little new at the formatting :)

Zebrafish as a model organism
I think there should be an article on this species as a model organism. This page isn't the best place to go into much detail on this aspect, as it's likely to be quite technical and there's clearly heaps of information on the subject from a range of different fields of biology. I think a longer article on this topic with a shorter summary section here would be ideal. Richard001 (talk) 00:03, 15 October 2011 (UTC)
 * Whether in an article or here, it might to good to add situations where zebra fish (danio) don't work. I run into this a lot in my readings on paleontology and molecular genetics. Danio might be good for medical research, but for understanding vertebrate evolution it's a bad a chichlids. Zyxwv99 (talk) 23:59, 11 June 2015 (UTC)

Links to other languages not displaying correctly
As of 8:53 PM Feb. 4 2012, the links to the article in other languages are all red and appear at the bottom of the page instead of in the sidebar. Something is wrong!

65.110.254.148 (talk) 02:54, 5 February 2012 (UTC)

Optimal temperature
I am fairly certain that zebrafish prefer temperature cooler than 22–28 °C (72–82 °F), i.e. somewhere between 18 and 25 °C. Is there a source that confirms I'm wrong and the article is right? Surtsicna (talk) 23:13, 12 December 2012 (UTC)

Citation needed
A citation is necesarry for this sentence under the section headings In Medical Research, Cancer: "Zebrafish have been used to make several transgenic models of cancer, including melanoma, leukemia, pancreatic cancer and hepatocellular carcinoma."This is certainly not common knowledge. A citation, along with more information about how and why zebrafish are used to make these transgenic models should be added or the section should be deleted.

Curtis Bixenstine (talk) 03:18, 4 February 2014 (UTC)

Renaming Article?
I was wondering about renaming the article. Zebrafish can refer to at least three species of fish. In the aquarium hobby, they are more commonly known as zebra danios. And this is the only place that I have seen them refereed to as zebra fish. — Preceding unsigned comment added by GouramiGirl (talk • contribs) 04:28, 28 May 2014 (UTC)

nonsense citation
An IP editor added which includes this bogus citation:

Neither the cited title nor the citation's author list match the titles and author lists given by the identifiers. The identifiers point to an article titled "Microinjection of Zebrafish Embryos to Analyze Gene Function" authored by Rosen JN, Sweeney MF, Mably JD. None of those authors are in the citation's author list and the citation has a completely different title.

I am not qualified to know which of the two named articles is the correct article (if either). But I am suspicious of any article text that has such a glaring error. So I deleted it.

Editor Elmidae has simply reverted me, which retains the obviously bogus citation with its displayed error message. Unless it can be repaired, the whole paragraph, in my opinion, is suspect and should be removed.

—Trappist the monk (talk) 15:41, 7 December 2020 (UTC)
 * this appears to be a simple identifier error. The intended paper is this:
 * - which, as noted, is a suitable reference for this statement. I admit I had not noticed that the identifiers and title link went to different targets; sorry about that. But with a minimum of AGF this is explainable as a small copy/paste error rather than anything nefarious. Fixed identifiers. -- Elmidae (talk · contribs) 16:36, 7 December 2020 (UTC)
 * Good, thanks. Assuming good faith is all well and good, but I have seen citations, quite a few, that were bogus like this one and that have been left to lie there for years before they got fixed.  Better that it is fixed now than possibly confuse readers for years.
 * I would suggest that your replacement might better use vauthors rather than lastn / firstn because this article is quite inconsistent in its use of author name list parameters but seems to prefer vauthors.
 * —Trappist the monk (talk) 16:53, 7 December 2020 (UTC)
 * Sure, swapped it out. -- Elmidae (talk · contribs) 17:13, 7 December 2020 (UTC)

Zebrafish genetics; limb study
https://phys.org/news/2021-02-fin-limb-mutations-zebrafish-fins.html

this article recently came out (paper here) detailing a study conducted at Harvard showing that the activation of a single gene in a zebrafish's genome results in the development of new bones, joints, and muscles into a limb-like structure. In a goddamn ray-finned fish, no less. Honestly, I don't think I'm quite...qualified to add something of this sort to the article, given my lack of in-depth knowledge of biology. I'm just dropping this here for folks who may wish to edit this new research into the article to mull over and consider. Cheers. DownAirStairsConditioner (talk) 23:22, 4 February 2021 (UTC)

Edit warring
This has nothing to do with Zebrafish and you clearly have no interest in this article. What you are doing is harassment and stalking. You have shown no interest in edit warring over "consistent citations" until you went through my history and found this conflict to join.

(The editor you are ganging with has been engaged in a long term subtle vandalism spree, running an undeclared bot to remove fields from {{cite}}s for some reason. I have not seen a productive edit for at least the last few years, instead he simply does this and edit wars over it.

Additionally this has resulted in such subtle damage that his bot - or other users later, or other bots - have converted a template to an entirely unrelated citation. With so little data to work from this is the inevitable result. This violates the basics of WP:VERIFY - others are providing verification, and then it is subtly falsified. The normal response doesn't happen - no one reverts the removal because something else has been substituted. When I told him this his response was not at all what I expected. He simply made it clear he knew that and was doing it anyway: The bot assumes that the pre-existing doi, pmid, and pmc are correct. In very rare cases, it has accidentally substituted the wrong ref.)

There is no legitimate reason for you to engage in this kind of long term harassment. You began doing this because someone else directed me to a talk page where this person wanted to talk me about my inadequate page creation skills. Instead that person never arrived. Then in another incident I told you I prefer to have publisher left in {{cite}}}}s. There is no reason for you to harass endlessly over two times that I attempted to Talk: about things over a year ago, one of which did not even involve you.

Stop. — Invasive Spices (talk) 25 November 2021 (UTC)
 * "harassment and stalking", so much for AGF. I've gnomed citations across thousands of articles for well over a decade now (and so did ). WP:CITEVAR is crystal clear that a variation of citations styles within an article is not something that Wikipedians support, and ARBCOM does not overrule that. made the article use a consistent style. You restored variations in style, non-compliance with various elements of WP:MOS like MOS:DASH. If a specific citation was mangled up, that specific citation can be cleaned up. But Bohog was careful in his gnoming, and reverting on the basic that a mistake might have been made is pure obstructionism and textbook WP:TE. &#32; Headbomb {t · c · p · b} 19:28, 25 November 2021 (UTC)
 * stop screwing up the article's consistency. You do not have consensus, nor support in any Wikipedian policy, for your reverts. &#32; Headbomb {t · c · p · b} 22:50, 28 November 2021 (UTC)
 * For anyone impressed by recent edits, the multidiff function is your friend. Or you could just examine any one of them individually. You will see what I mean. Invasive Spices (talk) 9 December 2021 (UTC)
