Ok ... So I have several clownfish in my 150 gal. (5 total) a Ocellarus, a Black & White Ocellarus, 2 Picasso's and a Tomato clown !! Everyone gets along fine and there is no fighting among them .. However My Tomato clown has started to fan out large sections of my sand bed in random places in my tank and it completely clouds out the tank .. The Tomato hosts in a large bubble nem and seems very happy !! What the heck is going on here ?? Do I need to add a second tomato to make a pair to make this sand storm stop ?? Or am I doomed ?? What do you guys/girls think ??
