Very tacky. I saw some of these at my local fish store recently. Very tacky.

I'm interested in them only to see if I can create interesting mutations by breeding them with normal Zebra Danios. But alas, they are illegal in California.

first: they can't breed
second: we live in California, anything and every thing can and has been illegal.

I saw a few at the lfs today. They really don't look too bad if you stick to a single color of em and dont put em in an aquarium with neon plants and black gravel.

on a side note, why start a thread in /tg/ and /an/?

Google it, they can breed. The company says they're sterilized, but successful matings have been documented.

>>they can't breed

thats what every biologist said before they dumped half a dozen "sterile" nasty ass carp species into our native waters

are those the same kind of fishes thant those poor "neon fantom" who are just transparent fish injected with chemical that colours their flesh, and that disappear with time?

No, "glo-fish" are transgenic Zebra danios. The original purpose for these fish was to "glow" when certain pollutants were present in the water. The experiment failed and an American company decided to cash in and sell them as ornamental pets.

They're the same as normal zebra danios, but tend to be slightly smaller than their normal cousins(possibly due to nutrients being used to produce pigment)

Aren't these the kind of fish that need a special kind of light to glow? UV lamp or something like that?

Yes, and ironically, they probably develop tumors from constant UV light.

UVA will at worst cause vitamin A issues, not tumors.

Really?

Question: When Genetic engineering is involved. Do the normal rules of genetics apply? What I'm driving at is, is the introduced bioluminecense gene dominant, recessive or what?

Reasoning from what I've heard about bioluminescence used in research lab, the protein is manufactured with a present gene, so it should be dominant.
>> Anonymous
>>330719
If a novel gene produces a new protein, it is always dominant. Recessive alleles usually either cause very little or no protein to be produced, and are overran by dominant alleles that cause the production of more protein.

For example blue eyes need two copies of an allele that causes very little brown pigment in the eye. The lack of the pigment causes the eye to remain blue. Even one copy of the brown allele causes so much brown pigment to be produced that the eyes will become brown. (For green eyes you need more genes and more alleles etc.)

they won't create strange mutations, it's just an additional gene.

>>330654
they can breed

>>330669
no, these are genetically transformed by inserting fluorescence genes, the painted tetras you are referring to are now illegal

>>330719
it is dominant because it only takes one glow gene to cause the fish to display the glowing color
