Are there any true aquatic crabs?

I really want a small crab- Any kind!!

Preferably something that will eat algae, but if not, thats okay too. (maybe it'll keep the Guppy population under control)
Would plants (bunch plants) allowed to grow from the substrate to the surface floating be enough of a perch for them to get air?

If not, is there anything that can survive permenantly submerged?

If there aren't any, I guess I'll stick to shrimps.

I considered crawfish, but I think they all get too big for a 10gal.

there is the thai micro crab. But it is still quite expensive and only available online. I would actually be worried about your guppies trying to eat them.

Crabs need a landpart to get out on to and no just some plants won't be enough.
How about Camballus patzuarensis orange (CPOs)??? Googel their pictures or look under my aquarium log at the CPO tank; I think you may like them.
Either case they won't eat algae - I'd suggest you eliminate the reason that's causing you whatever algae you have growing there

If you do decide to get any, be aware that they LOVE to escape... I have found them out on the floor, hanging off the back on an airline, and INSIDE my filter housing! No more of 'em for me, LOL

How about some shrimp instead? They're funny, entertaining creatures.

I have a glass shrimp in the tank with the guppies, I've been playing around with the more shrimp idea before now... I'd like to breed them too...

maybe a trio each of glass, amano, and red cherry? or think I'd need more for them to breed? (in a seperate 8gal thats just getting dusty in storage)

While there's no risk of hybridization with the named shrimp; the glass shrimp will eat smaller or sick shrimp, tat said the likelihood of the hatched eggs surviving is very slim. Therefore I'd either set up a shrimp farm or excl the glass shrimp from the list.
That said your best bet for breeding (apart from the necessary water quality) is sep set ups for each and then start with groups of 6-10 shrimp each.

There are mexican dwarf crayfish that stay under 2 inches, readily available on aquabid.

Here's one next to a mystery snail.
