What types of fish or snail anything really would be good to stir up my sand in my 55 gallon. I had Sulfur dioxide form under that tank earlier this year and I took it all apart scrubbed everything and I’m looking to get it up and running again. I will rake the sand every week but I really want something else to make sure this doesn’t happen again. I think the problem was I left some sand in there from when I had chiclid and I capped it with 3 inches of gravel and that really caused me issues. This scape is an island scape in the middle with plants on the island and the surrounding area is just sand . I think I’m gonna stock some neons in there but any ideas to keep that sand clean?
