I have a few clowns in my tank and they all get along. I went out yesterday and got a moroon clown and all of a sudden my other clowns turned into mini-pirahnas. I saved my clown and put him in a clear breeding tank inside of my main tank to let the other clowns get used to him being in the tank. 24 hours later i put him in the tank when it was dark and the next morning they were back at it again! So I repeated the same steps as above. Any other ideas??

I had the same issue when I put my Maroon from my 12 gallon into my 100 with my Perc. Usually, the Maroon's are much more aggresive, but the Perc beat the crap out of the Maroon. My Perc's been in solitary in my fuge for the last 8 months. Maroon's and Perc's don't seem to go well together. Your best bet is to keep the Maroon alone or bring him back to the LFS.

yeah i wuold just advise not putting two diff species of clowns in one tank.... problem solved
