MTS strikes again!!! mom has decided that ONE tank at home is NOT ENOUGH!!!! SOOOOOOOOOO we went out and got her a tank for her cubicle at work...and we're getting a 20 gallon aquarium for home. we picked out a GORGEOUS purple boy, whom she named Louie after my dentist. (long story

) and he loves it at work because everyone coos over him, and we've gotten one of mom's friends into it too!!! BUT i noticed that his dorsal fin is curled. just at the top. it's fine when he's swimming, but when he stops it curls up again!!! at first i thought it might be stress, but maybe it's a nutritional imbalance? any thoughts
