cool tank, but you have an issue with snails. loaches are the best to resolve that. clown loaches are good, but you have to keep them in groups and they get about a foot a piece. skunk botia loaches are perfect. they only get about 2 or 3 inches and they are pretty aggressive too.........i have 6 in my tank now with 2 peacocks, 2 haplochromis, and a 10 inch ropefish.
