VIOLENT ZEBRA DANIO (killed my guppy)


ēI used to have only 2 zebra danios in my 20 gl. tank.

ēI saw that one of them was nipping other fish, such as the other Danio, guppies and platies.

ēI did my research, and found out that they are Schooling Fish, and that they can become violent if they are not in a bigger group.

ē I immediately went out and got 3 more, so now I have 5. I thought the problem would be fixed, and that he would be happy and quit harassing others.

What are the water parameters? Sometimes if the water parameters are in an unsafe level the fish can act very aggressive.

Easy - take this fish to the store and get a different one.

New to FW fish? First tank in a long time or EVER??? Need some info on keeping fish?
