Could I put anything in a .5 or 1 gallon tank? My sister has some extra tanks that she’s offering to give me for some snails but I feel like my snails deserve something a bit bigger.

I’m not really sure, honestly… I’m not well versed in micro tanks or what sizes qualify, and how the heating and filtering works on such small tanks.

Suggestions, anyone?

Tiny snails like pond snails may do OK, but, by and large, no. You could try an aquatic insect or something like a daphina culture, but even that has the potential to ‘crash’ in such a tiny water volume. 

Personally, the only things I’d keep in tanks like those are plants. Maybe small terrestrial insects. They can work really well as terrariums and vivariums as long as you select inhabitants accordingly, but they’re really just too small for any aquatic animals.
