That depends on the puffer you get. Saps then daily. Congo I do it twice a week. I usually fast him 1 day a week too.How often should I feed snails? I have mussels, bloodworms, shrimp, other freezedried foods and pellets too.
In my 4ft tank, there are 2 bichirs, 2 ropefjsh, 1 african knife, 1 bushfish, 2 eels. One tyre track and one zig zag.
