I have 1 celestial pearl danio (galaxy rasbora) left (the others all didn't make it) and 6 glowlight danio (danio chaprai) in a 10G. I think they'll play nice together but will they cross breed? I plan to get more CPD but only if they won't cross breed. Both are stunning fish but I'm rapidly running out of space for fish! I've got 4 tanks, totaling 132 gallons. I don't think I have space for any more tanks!

most glowlights are sterile, but if they do spawn, I dont know.

Wow, I didn't know that most glowlights are sterile. Why is that? Are they genetically engineered?

Aren't glolights dyed? If they are you won't get that color in the spawn

Glofish are NOT dyed they are genetically engineered..Now they are just born that way..When they first did it they injected jellyfish DNA into the egg but then those spawned and made more glofish....Glofish used to be sterile but for the most part are not anymore..They made them sterile so people couldn't breed them..But now most are able to spawn.

hmm, i thought it was something from an anemone (i dont remember what the actually part is called)? but maybe i'm thinking of something else?

CHoffman

Nope your right...They actually took dna from both...To make the different colors..I forgot about that..lol...I can't remember which color required the different DNA but still very strange.

Glowlight Danios (danio chaprae) as mentioned by the orginial poster are not the same as GloFish.

I went to their website but all they say is it's taken from marine organisms. I'll have to find where I read that..I might be wrong.

OH my goodness. ...You are sooo right..thank you..I saw the genetically engineered part and went with it..Sorry!!!!!..Thanks for the clarification Jgon!!.
