My two new clowns sleep at the very corner of my tank (and stays around that area for most of the day as well). The last few days I've noticed one of the clowns (i'm assuming the female because its the bigger of the two) going bonkers swimming against the glass on the side opposite where they sleep. Same spot every night and always when only the blue lights are on. At first I thought it was due to the recent heatwave and maybe the fish was uneasy with the tank temp, but it kept happening despite the cool down recently. After doing a little googling, some folks think it's attacking it's own reflection and that it should stop eventually. Totally makes sense. Others say that clowns really need somewhere to host where they can feel safe, otherwise they'll act all crazy.. also makes sense. I just got an RBTA last week but the clowns are more afraid of it and the dumb anemone can't make up it's mind and is at the back of the rockwork at the moment. I'm about ready to go to homedepot and buy a flower pot for them to host. It's going to look awkward in the tank but maybe i'll just cover it with GSP lol. So from those who've owned clowns (which is pretty much everyone here i think), how important is it for this fish to have something to host?
