Blimey, are you saying that common snails can reproduce without a companion? I recently saw a small snail in my tank. I figured since it was the only one it wont do much harm. Now I'm a bit scared since I have heard of horror stories on these forums of tanks being overrun by snails. I haven't seen the snail for quite some time. How can I rid my tank of the few that might be there? I reckon it will be easier now than laterIf you want a snail, get a single apple snail. They wont' reproduce without a companion.
Yes, the common snails can reproduce on their own. That's the main reason they are such a pest.
For loaches, all the botia species should be kept in groups. 3 absolute min, with 4-5 being much better. Botia striata aren't super common in LFS, but not rare either. It seems to depend on the fish store.
