Did some cleaning in the tank today, scrapped all the algae off the glass and wow, does it look good. While I'm doing this, my daughter says, oh, the sailfin was nipping at your brain coral earlier today. Nah, couldn't be, but sure enough, I watched him and he's going to town on it. I really didn't want to move the brain to the other tank as the 180 doesn't have a lot for corals and this one was doing awesome. But he won't stop, so rearranged things in the 55 and moved the coral over. Bad bad bad fish
. Does this mean I'm going to have problems with him going forward??
