I've had 2 clownfish in my Biocube for 2 weeks now. Three times, I've come home or woken up to seeing only 1 of the 2 fish in the tank. They keep getting themselves somehow into the chamber on the left hand side where the pump resides. Both the bigger clown and the smaller one have done it. I can get them out easy enough, by turning off the pump, pulling it out of the chamber, the chamber fills up with water and I fish them out. But this can't be a good thing for them each time.
Any suggestions how to prevent this and any idea how this is happening in the first place? The water level seems right as I've got it between the minimum and maximum level.
