Glofish are genetically altered Zebra Danios (Brachydanio rerio). They have had a jellyfish gene added to their DNA to make them glow. They are egg layers and so can not get pregnant and give birth. When they spawn, the males drive the females who release their none adhesive ova which are fertilised by the males as they sink to the substrate.
If you take care of them there is no limit!
The GloFish will have a bloated look and will be fat. If you compare it with the other GloFish , you can usually tell the difference. I'm not sure right now, as my GloFish is also pregnant.
Supposedly, glofish can look pregnant without actually being pregnant. If the female is getting enough nutrients and there is a male glofish, it's possible the female will lay the eggs and have them fertilized.
Glofish were created in 2004.
What s "mate"?
I have a pleco and a Glofish together.
10 hours
you leave them in a tank with plants and rocks and a filter and a air pump with a light then leave them alone for a day and she should be really fat. then you will know
No glofish are a patented strain of zebra danios and its illegal to sell, trade, or even purposely breed glofish.
Their bright colors make it look as if they glow in the light.
She may never want to mate with him, but just be patient. It may take some time for her to allow him to mate with her.
Maybe a little larger, but around the same size of when you first got it.Hope I was of help to you!
