why are zebras the glow fish and not guppys or mollies ?ARE THEY WORKING ON OTHER fish that can glow.do glow fish come in other varities?

this is only an assumption, but danios are very hardy fish that are tolorant of a wide varieties of parameters and degradation of water quality............The whole glowfish thing was started to detect certain pollutions in rivers and streams, i would guess they started with a very hardy fish to tolorate the varied waters they were placed in.......Google glowfish and there is a site that explains it better than i can for you

Dont buy glo fish

okay I know how tempting glow fish are, but the whole glowing process is done by "inserting the bioflourescent gene that makes jelly fish glow into danios to make them glow", or so they say. But what is really done, is that they coat the danios in really strong dye that is sort of neon-ish so they seem to glow,but towards the end of their lifespan or so (a few years) the dye will begin to wash off. The reason they need danios for this is because danios are extremely hardy and are practically the only fishes that can withstand being pulled out of water, coated in dye so strong it sometimes blinds them, and being dumped back into the water so they can breathe, and pulled out again a few more times for more coatings. Trust me, glo-fish may seem cool and all, but it's really just cruel.

Not to drag this discussion off topic, but Krish, where do you get your information? The reason I ask is because I was thinking of glofish in my tank, but ultimately decided on their non-flourescent brethren. I looked at all the glofish, and they looked like their coloring was natural, that is to say their stripes did not look like they were covered in dye, rather the stripes were a light color. Their eyes appeared clear to me. Would dye also cover the eyes? Thanks for the reply.

i would also like to know where krish is getting that information. it is entirely contrary to everything else i've ever heard. getting colors to show up through genetic manipulation is not that difficult.

as to why danios and not other fish, i'd have to agree with the hardiness suggestion. and probably the fact that the natural color is so light that getting the new color to show up would be really easy. "clear" fish probably wouldn't work because they don't naturally have any color so getting a color to show might not work. i don't really know, but that would make sense to me.

I actually heard this from my LFS clerk. Not sure if she's reliable, but.... I didn't think the Glo-Fish were safe either. I dunno. :dunno: I guess you guys should just decide :|

While the colouration in glofish may be genetic modification and not painting or injection of dyes as is done in some other types of fish, there are many of us who think the fish should not be purchased. It is only in NA that one can now get Glorfish; their importation is banned by the European Union, which should tell us something.

if the colors were added due to genitic manipulation it could be that the genes are compatible or more closly related to the jellyfish gene

and if they were dipped into a dye would the dye not leech out into the rest of the aquarium aaltering the ph or harming the other fish??

or even tinting the color of the water since the dye must be a strong one
