    It dependes on what the size of the tank is. For a 10g you could hace about 3 fiddlers but only 1 RCC. You do know that they have to have access to dry land since there not fully aquatic right?

    It would be a 10gal as of now but i might be getting a bigger one. I know they need land they would be the only guys in the tank. but i would only get one male as i heard that was best. and lots of hiding spots and a tight lid.

    You would also need a heater since both like 75*-80*f temps. With fiddlers a good ratio is 1M:3FM But with RCC IME both M and FM are to aggressive to have any more than 1 in a 10g. It's usually recommended that RCCs have 10g for 1 and then 5g for every added RCC.

    ok that seems resonable. But do you know how messy they are or what kind of water changes im looking at if i get them. I relize it will very by the number but just ball park.

    Well for the fiddlers I have I have never seen any feces on the sand. And I do a 50% wc every week but that's because I only have 5g of water in my 30g and I have an in tank filter. If your not gonna do a filter and theres only gonna be a couple of gals then I would do a 100% wc. It was about the same with RCCs.

    ok cool. i do plan on putting in a filter though but regular large water changes is what it sounds like.
