I found a HOB filter made for NANO's up to 3G, so we put it on the 1G and put gravel in it, and filled, put the snail in, and in minutes he was all around the thing. considering that he is always in his shell because the honey's picked on him. I think that would work great for a little while. and its got a 3G filter on it!!
Later, we want to put a few shrimp in it with some java moss...
BTW, how is the purple snails growing? ready to ship? Do you have any Apple snails?
