id take out the humus (they need a 75) and get a coral hogfish. they are a great fish, full of color, very active, and never skip a meal. it would also be a perfect fit for that size tank. puffer will also back me up on how great these fish are. just curious, but what kind of substrate are you using? a hog, dwarf lion, and snowflake would be great in that size tank. you could maybe squeak by with one humu in there, but it would be pushing your bio load. what are the dimensions of your tank? sounds like a great setup. im assuming you have a good filtering system with those fish. bo
