I have had 2 clowns in my tank for awhile now good year atleast and the past few weeks they both have been hiding inside my rocks never see them come out untill lights go out.Then they come out and just swim around the lil cave they hide in.Tonight the smaller one was twitching around in the water while the bigger of the two stayed by this rock both never really leaving the rock they hide behind during the day.I have wondered if they were trying to mate or something but have never had this happen.Any ideas? Only fish are the 2 clowns,few snails, and 1 hermit.:fun2:
