Definitely dont get damsels... I made the mistake of buying two blue damselfish to help cycle my tank, but I didnt realize how EXTREMELY aggressive they are. I took the really stupid route and bought the two biggest ones my lfs had (they had bold colors so I figured them the healthiest), and as soon as they were introduced all heck broke lose. Within two days the smaller one was looking ragged and always hides from the bigger one. I shouldve listened to the guys here on the board!!!
I have no clue what I should do with them after my cycle is finished - Im afraid to add any other fish to my tank. Still, I dont want to return them to the fls to suffer the same fate again. Maybe this is a good excuse for another tank...
