My clowns have been "fanning" or digging a pit in their corner of the tank, and chilling out there all the time.
O.k.......what the heck, as I'm typing this they are both suspended in the water with their heads facing up and tails down and start to vibrate...then swim a bit then stop and vibrate....what the heck is that about?
Oh and the little clown (they were bought at the same time and same size but one is large and one is tiny, figured male and female). but yeah the little one is protective, bites the heck out of me everytime I'm messing in the tank with my hand.
