Small All-invert Tanks

[Malkavian]

Not in a position where I can "do" larger tanks just yet, but I've toyed with the idea of taking one of my small tanks (previously inhabited by reptiles or terrestrial inverts) and turning it into a small planted invert habitat, maybe shrimp, or crabs, crayfish...however it seems like it might be tricky to get a variety of critters in a tank that size for worry about unauthorized snacking when they go to molt, or outright predation.

I was thinking a few shrimp of different species, and maybe a snail. An alternate setup of one or two of a predatory species might be interesting as well, again given that they'll coexist in the small container. I'm sure there are possibilities that I haven't considered.

Am I crazy for considering this?

Definitely not crazy, there's a number of people who do this I believe.

Crabs wouldn't do well in such a small space, except small saltwater ones. Most predatory species would require bigger space as well.

But smaller shrimp (the commonly traded caridina and neocaridina shrimps and ghost shrimp) would all do well, as well as the smaller snails.
