Dwarf / Pea Puffers are great!
I highly recommend the dwarf puffers for all your tanks. I have at least one in every tank (except my crystal red shrimp breeding tank) and they keep the snails in check. In fact, they seem so self-sufficient that I rarely supplement their food source. When I do feed them it's generally LIVE brine shrimp as they are definitely finicky eaters and will only eat live food (from my experiences). They really chase those live brine shrimp, and it's fun to watch. Also, they WILL go after larger snails, so if you find one take a close look at it if it's crawling on the glass because you will probably see "chunks" eaten out of it's body. It's kind of morbid in a way, since they can't eat the whole thing at once (sometimes the snails they go after are bigger than their entire body) they take a bite out when they can. Eventually you will find just the snail shell somewhere in the tank as they finally got to it.
Anyway, they are great, but keep in mind that they will sometimes bother other fish so you need to pay close attention to that in a smaller tank (like a nano). The people at Aqua Forest in San Francisco are pretty good about recommending fish compatibility with these guys, and they sell them for $5 each. They are also VERY cute and fun to watch, and they seem to want to watch what you are doing if you are in the same room with them.
I also have them in tanks with Amano and cherry red shrimp and they don't seem to bother them.
