Lightly planted 45g tank intended for fish (primarily interest), currently cycling. A couple of Ramshorn snails snuck in on plants (I assume), in fact eventually 3 showed up. Today I noticed a large number of egg deposits (about 6-7) all along one corner of the tank, and at least one on a sword. So... I like the idea of a few snails cleaning up continually, adding a bit of interest. Ignoring the idea of "what is an aesthetically pleasing number", is there some guidance as to what is a good, healthy number of snails in such a tank? That balances their cleaning propensities against their bioload? And any idea how many of these eggs are likely to survive, I have 5 tetras and a raphael catfish in the tank -- if they all survive it's going to be a LOT of snails, so considering getting rid of some of the eggs (knowing that even if I got rid of all I can find, there are probably quite a few more also). So... assuming I can manage to control the population at all... what's a good number for a planted fish tank?
