Glofish are genetically altered Danios and they grow to about 1.5 inches long. They will mix well with most Tetras including the Blackskirt (Blackwidow) Tetras that grow to around 2.5 inches long. Just remember the golden rules. All tanks need a cycled filter and a weekly water change of around 50% and "1 inch of fish needs a minimum of 1 gallon of water" so that you don't overstock.

How long does it take for glofish to mate?

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.


Can 2 glofish live with an 1 long finned black skirt tetra in a 3 gallon tank?

No. The tank is far too small to hold more than the Glofish (genetically changed Danio malabaricus) ). A (nominal) 3 gallon tank when it has water to within an inch of the top and a couple of inches of gravel as a substrate will only be holding just over 2 gallons of water. (Glofish) Zebra Danios grow to around 1.5 inches so you will see that the 2 glowfish (Danios) add up to 3 inches by themselves. So they are too much for the tank. The Black skirt Tetra (Gymnocorymbus ternetzi) grows to over 2 inches so it would need an absolute minimum of 3 gallons of water to live in and 10 gallons is the recommended size tank for them.
