Yellow tang becomes aggressive

[Lance75]

My yellow tang all the sudden becomes aggressive chasing my blue tang around like crazy. They both put in my 215 gal tank at the same time about 6 months ago. What is with this abnormal behavior ??

If your blue gets too beat up I would pull the yellow for a week and rearrange the your tank. One of them will be dominant, the trick is not loosing one.

Actually, it is normal behavior. Tangs many times will fight and spar with each other, especially if they aren't eating well. One additional reason we recommend big aquariums to house them. Try getting them to chow down some more. Fat tangs don't fight as much.

I know yellow tangs are quinticential fish for saltwater tanks but every one I have ever had has leaned towards a nasty personality. They can be a handful.....out of nowhere too.

I think Grey is right in saying to keep him well fed with frequent feedings. That will probably calm some aggressive behavior.

They are all surgeon fish's and have that barb in the tail for a reason. Mine rarely hurt each other.

They r fed very well with mysis shrimps and flakes twice a day. I also have a blonde naso tang in this tank and the yellow one doesn't chase him.
