I bought a clown pleco yesterday with only doing limited research, not a mistake I usually make, so here I am. Lol. I picked up 4 salt and pepper corydoras on Friday and then went back to get more on Saturday. They had one left so I got it and a clown pleco. All of these are in my QT tank and all day yesterday the clown pleco just hid under my sponge filter which I know they are hiders. But last night after the lights had been off for awhile I went over with a light and looked in. The clown pleco was out and very active while the corydoras where just laying around on the bottom. So my question, is this gonna be an issue with him being so active at night and disturbing the corys? Also, could the clown get very aggressive about territory on the bottom of the tank?
