Aggressive Clarkii

Hi Guys,

My female Clarkii has become very aggressive over the last few weeks. So much so that I think that my flame angel was afraid to come and eat. I tried spot feeding it but it was afraid of everything. I found it one morning after it had not eaten for 4-5 days. My blue hippo ate happily on Sunday when I fed the tank nori in the morning, but was not there for an afternoon feeding. She hasn't eaten since Sunday morning and I am afraid the same thing will happen. The hippo will come out occasionally come out but hides when I try to feed. The large clown chases all of the other fish around. I saw the tang and clown doing a lot of tail flashing the other day. No nipping but just being a PITA. These fish have been together for about 6 months and I don't know why it has changed all of a sudden. I am almost to the point of pulling the large clown and being done. She used to just harass the smaller clown, but it has become ridiculous. Any recommendations on dealing with an aggressive fish? Thanks!!!

Regards,
Ivy

 

the clarkii is on the aggressive side everytime i stick my hand in the tank mine attacks me, if you have a QT i would suggest putting him in there for a bit.

 

Thanks for the advice. I have a 12 gallon plastic tank that I bought for a QT but never set up. What would be the best way about going and setting it up? I have all of the necessary equipment. Do I just add a piece of PVC piping and water? How often should I change the water? I haven't set up a QT or hospital tank before but want to save my tang if possible. Also, what would be the best way to catch him. He is crazy fast and I really would like to avoid tearing down the tank. If I do QT him, do you think he will be aggressive again? Thanks and sorry for so many questions
