Actually put a descripton on the unknown chemical.You know,like something happend and they found out what it does.
Mostly because no one wants to pay the price of a arrow goldbulb for a useless fish.You know,like a twin fin beta that sells for 5 bucks.

Another thing I would like to see is a predectioon for borth from a pregnate fish.Cause,I hate it when I turn my back and a baby has died from hunger.
