Nippy Angelfish..

[BigFishKeeper]

Hello. My three angelfish are being real nippy. They keep nipping at my silverdollars and tetras. Is there any way I can put an end to this?? If they don't stop I am going to have to take them to the lfs for store credit.

you could try adding tall vertical structure.

but remember, you are keeping cichlids here..and they can get nasty from time to time.

Could the issue be you have a pair defending a breeding territory?

What size are the Angels and what size is the tank?

I have a 75 gallon tank with 15 or so Angels and I have bread and raised Angels from eggs to full grown adults. Angels, as are other Cichlids, extremely territorial. You will see a mated pair guard one side of a tank and any other fish that come close get attacked. You will see them threatening and nipping eachother to keep the others away. When they become sexually mature, the behaviour gets worse and more fierce. This is what's going on. You either need a bigger tank and/or more hiding places or get rid of the aggressive fish.
