There is another thread going right now about starting a snail tank, and it is relatively easy to do, except it took me a while to get a crop going. If you want snails, they won't lay eggs, and if you don't want them, you can't get them to stop!
I think the fact that the puffers' eyes are facing forward and are not laterally placed makes them seem to have mammalian faces, or something, because I cannot resist them looking at me. I saw some real tiny baby dwarf puffers today at the new LFS
) so I might be adding to my small pack, if they'll tolerate new members. Maybe after quarrantine they will be big enough to hold their own, I hope.
