    Hi everyone, I'm gonna get five to ten crayfish, five blue marble and five marble crayfish. How many gallons need to be my tank and if they can live together. What u recommend for substrate nothing, sand or gravel? Is true that this crayfish can clone themselves? Thanks

    Certain species of crayfish can clone themselves.
    The thing with crayfish is that they are highly opportunistic and cannibalistic. You'd need a very large tank to keep all those crayfish out of each other's way especially when molting. Even then, your population might eventually dwindle to one or two.
    If you would like to keep crayfish together, try with dwarf species like orange dwarf crayfish. If you really want to try with bigger species then you should have tons of hiding opportunities.

    Thanks Madagascariensis, well I think I have to make a lot of hiding place because I order them and they are coming today. The aquarium I'm planning to use is a 3 ft and think is 30g. Is this okay.

    I've been doing some reading about marbled crayfish. I have a single native crayfish in a 10-gallon tank and I was curious. People raise them for fish food or fishing bait, so keeping a group together is not unheard of. I've seen multiple places recommend that you build a "crayfish apartment" out of stacked short sections of PVC pipe, and that each individual will select one pipe section and make that her home. You might look into doing that.
    300 gallon mega tank: sailfin pleco, clown loaches, silver dollars, roseline sharks, congo tetras, new world cichlids
    125 gallon office tank: Africian cichlids, synodontis catfih
    75 gallon community tank: bolivian rams, black skirt tetras, dwarf neon rainbowfish, corys, harlequin rasboras, otos, bristlenose and bulldog plecos, assassin snails, various shrimp
    60 gallon goldfish tank: fancy goldfish

    Thanks everyone, sorry for the late reply. Right now they are in a 30g aquarium. They are doing fine and I make a 3 floor apartment of pvc tube. They grow fast and I think that they have clone, not sure. If they have clone I'm thinking of making another place for them.
