How much do snails contribute to the bioload?
I Hear stories of people with hundreds of MTS. I also hear people with lots of ramshorns. Do the snails contribute heavily to the bioload of the tank in those numbers? Compared to fish, how do they contribute to the bioload? With snails that are larger like mystery, nerite, and white rabbit snails, how do they contribute to the bioload? Would a large population of small snails or a large group of larger snails compete for available oxygen with the fish?
A little more specific. Say you had a balanced bioload for any given filtration system. Could a decent amount of snails be added without an adverse effect where an "equal" number of fish would?
