Thank you all! & thanks sirminion for cleaning up the picture, that's much better! The tank is 55 gal, I have 7 clown loaches, 4 corys (2 albino 2 spotted), 4 kuhli loaches, 2 golden cae's, 1 cherry barb who are permanent residents. Also 2 bala sharks (these came from a pet store's "return tank", they were housed in a tank with oscars among others) they were beaten up pretty badly so I brought them home and plan on finding them a bigger home soon. There are also 2 bumblee gobies (which I just got last weekend because they were so adorable), after reading some stuff here I know I will need to find them a new home also!
