I already have 2 zebra danios, and I'm stuck in between 2 types of fishes that I want to get, the Guppy and betta, I would love to have both of these!, is it advisable? I have a tank of 96ltr
Yup .. Just read a thread that said any fish that has long fins could be mistaken for a betta. So don't put a betta with any fish with long, colorful fins.
Any fish with long fins and that includes fancy guppies, cannot be placed with bettas unless you want to have a lot of trouble with fin nipping and possible worse. Bettas will attack anything it interprets as another Betta and that includes fancy guppies and any other fish with any longer fins.
