Catfish problems

[avelyn]

I recently had a finrot problem in my tank
it has now been treated and all is good
I had three goldfish and 2 sucking catfish.
Today i bought 3 new goldfish and i noticed the catfish is chasing all the fish all the time as well as the other catfish.
the other is smaller and isn;t doing this
it's just the one fish, he seems very territorial
should i remove him from the tank or leave it???
any adivice would be greatly appreciated

I've trained fish of all types, aggressive and community, out of this bad habit by taking a piece (stick) of balsa wood (because it's soft and flexes) with rounded corners and gently tapping the fish whenever I see this happening. It takes a long time commitment, because for a while you have to be vehement about watching the tank to catch this behavior. i know it's 2 months after you originally posted but I hope it helps.
