I just got a saltwater tank a few days ago.   I have 5 adorable mollies.  there is one thing that i noticed today.  one of the fish keeps getting stuck on the filter.  when i first noticed it i thought it was dead.  when i tried to get it out it swam away.  why do they get stuck?  is there something wrong with it?
