the marineland is for a 50 gallon is pushes quite a bit of water.. should i turn the light on the save my last clown??? the reason i got the tang was because i was going to upgrade to a 125 .. but so far this takes some time to get used to.. the all the fish last night almost looked like they were shedding.. not to sure what went wrong exactly but sure dont like losing fish
