I have 4 clowns split into 3 different tanks. A pair in one tank, and 2 in two tanks each. The pair sleeps at the corner of the tank where some of the pumps are. Its a little cozy even for me I can totally understand why they would pick that spot. One clown in the sps dominated tank, would find any where with the lowest flow to sleep, most of the time next to a leptastrea. The final clown who is the newest, immediately took a liking to my torch and my xenia. She would alternate her hosts depending on the lights. Lights on, it’s the dragon soul. Lights off, it’s the xenia. I guess she figured, why limit yourself.
