Do snails and shrimp go by the 1 in. rule thanks.

most shrimp dont count as anything on the bioload. snails are heavy waste producers, so yes they get added i belive

That is the same as I have heard....shrip contribute almost nothing to the bioload. Most snails will quickly overpopulate a tank, best to avoid them unless you are really in love with them. There are two kinds, I believe, that DO NOT reproduce asexually. I think these are the mystery snails, but I could be wrong. I know that I have a single blue mystery snail in my tank and it has stayed that way for over 6 months.

Shrimp are pretty low on the bioload so you'd mainly look at if the fish would feel hungry looking at them. Snails are tremendous waste producers so you'll want to allow a lot of tank capacity for them, depending on which species you get.
