We have some black and brown "shelless" snails in our tank. They work hard, but they are increasing their population. This a.m. I watched one of them - seriously - smoking [?] and he kept ejecting small smoke rings for a while [talented too]. So, at what point are these things a problem to be dealt with as opposed to an oddity. Right now I can count about 5 or 6 of them, but wonder if we should be trying to wrestle them out or.....just not sure.
I am concerned that what I saw was spawning so I thought I would like to know what others have experienced with these.
