Psycho Yellow Tang

[dallen2233]

Well let me start by listing my setup:

6' x 3' x 2' plywood aquarium

live stock:
1 Red Sea Sailfin Tang (5-6")
1 Yellow Tang (3-4")
1 Snow flake eel
1 marbled catshark
1 cleaner shrimp
9 hermit crabs
1 sand sifting star fish
and some zoanthids

Well the first fish in there were the tangs. At the beginning I had the two plus a brown powder tang (5-6"). Over time I would see them fight every once in a while. Then one week the yellow tang started to frequently attack the brown powder tang. Later that week the brown powder got stressed and died. Now a couple of months later, the yellow tang has stressed out my sailfin to the point I didn't think he was going to make it. I was able to catch the yellow tang and put him in the sump. The yellow tangs aggression doesn't stop at other tangs. Hes tried to attack the eel along with the shark. Then he stopped attacking the shark once it go sick of the yellow tang and bit him. Anyone got any ideas?

Tang sushi! Offer it to a fish store or give it to a local aquarium.. Get rid of it

I agree - he needs to go. Can't exactly try psychotherapy.

This one I was treating for ich via tank transfer. He was not happy with me! He calmed down after I put him (and all the other fish) back in the DT. I put him back in last. It may be that yours will respond to an attitude adjustment.
