Crab only tank?

[Be4u]

I have a friend who wants a crab only tank. Can this be done? All he'd really need is a regular filter and live rock huh?

Would different ones get along?I guess if enough food is their?

What kind of crabs?

I used to go to a bar we called the crab tank. Crabs are opportunistic so you could lose a smaller one now and again. But as long as food was available they should be OK. If you kept wolves overfed enough you could probably house them with sheep.

Arrow, Porcelain, Lightfoots, emeralds, dwarf Blue hermits, Sand sifters.

He has a freshwater that housed oscars till today. He gave the fish away earlier today. He wants to use his freshwater filter, bubbler. Basically a freshwater setup with saltwater to hold the crabs.

I do know that the porcelain crab is very territorial so that will be the one to watch. everything else should be fine, but in all honesty every fish is different in your case crab. So it's going to be a trial and error type of thing. Good luck
