Crab and crab in the same aquarium?
I currently own a 110l aquarium and have a pair of CPO crabs in it, with lots of Neocaridinia's and very peaceful copper tetras.
But since I'm a big fan of invertebrates, I'd also like to get some ghost dwarf crabs (Potamocypoda pugil), as they don't grow much bigger than the CPO itself.
I know that keeping two different species of crabs isn't a good idea, as they're very territorial. I'm just wondering if that's the case with crabs, too. Could that possibly work? Or is it 90% guaranteed to be a massacre?
Generally bad idea. Animals that are not well established would always keep in the art pool. Just for hygiene reasons.
You should not do this.
