What Fits In A 10g Other Than Fish? Crab?

Hello! Our old betta, who lived with 2 nerite snails in a 10g, has died. My son has been wanting crabs for forever since that is his favorite animal. I have been researching Halloween crabs, hermit crabs and red clawed crabs. All seem to need a 20g+ tank and I don’t have room for one that big (I already have a 55 gallon community).

Are there any other variety of crab that could fit in a 10 gallon that is easy to buy? Or anything else besides fish and shrimp? I want the best for the crab/animal, so I want to make sure it has the best. Thanks.

 

Tia micro crabs. Drawf crayfish.

 

You can house small lizards and newts in a 10 gallon.

I looked them up, and those look way to close to a spider for my liking. Haha

 

Fire bellied toads, Pacman frog, or eastern newts.

 

Freshwater pom pom crab. Super cute

 

Vampire crab.

 

Pom Poms for freshwater.

You could also get fiddlers but they are low brackish and need access to out of the water. Your merited could acclimate to brackish too

I have both and they are both great
