I have three clownfish. When I went fallow and put them in QT, two of them beat the crap out of the third and I had to put an emergency 10 gallon up to save it. Now that the fish have been back in the main tank (75 gallons), I'm contemplating putting the third one back in the main tank. However, I'm afraid they may go after him again. Anyone have experience with three clownfish in a larger tank? When the three were in the main tank originally, there weren't any issues.
