tiger botia (multiple)
I've introduced two tiger botia into the smaller fishtank in hopes that they will devour the burgeoning hordes of Malaysian trumpet snails - a nuisance species. I counted about 30 of them on the surface the other night. [They're sort of nocturnal- they get active when it is dark. Counting them is one of those things you do after they've had several hours of prolonged darkness.] That was 30 that were sizable - there are vastly more of them in the tank, but they're either deeply buried or too tiny to easily see.
Botia-variety fish are basically loaches. They get big. These two are about the size of a triple-A battery. If they get too big, I guess they'll have to go back to some pet store or another...
