BIG snails
i bought many golf ball+ sized pond snails, in the foolish hope that they might be enough of a pain to eat, and there might be enough of them, that they might last long enough to reproduce. The bottom of the tank looks like I intentionally used snail shells as a substrate. I got lots of live plants too, and they have made a mess of those as well, but they won't be getting pellets for awhile. I think I may have to start a little tank just for a few plants and snails. They were big snails! I don't know how they did it. The curve of the shell was big enough that I didn't think they could get their mouths open far enough for a good chomp, but they showed me!
