    hey guys, so i found a offer online for 10 self cloning crayfish online for a great price, i have a 30 gallon tank and its a peaceful species so im not worried about space, what im worried about is reproduction. i know these are known to reproduce like crazy, and that they dont eat their young so chances of young thriving is pretty high. i dont want my tank to be overpopulated by these crayfish so im curious as to how i can control there population.

    i will also speak with my lfs to see if they would be interested in buying them from me but that is doubtful.

    any advise will be gratefully accepted. if there is no way then i just wouldnt get them.

    thanks

    If you can find someone who has cichlids large enough to eat the babies, that would be best.

    i wonder if the cichlids would eat the adults as well? if not maybe i should just get some of them to control my in tank population?

    They would when the cray molts, but the cray could eat them while they sleep.

    I'm sure they will cannibalize each other once the population gets out of hand.

    they are a lot less likely to cannibalize than other crayfish species unfortunantly. they only grow to a max of 2.5 inches so its highly unlikely that they can take down a fish the size of an average cichlid. i think most omniverous fish would be interested in baby crayfish as a meal would they not?

    That will depend on how much you feed them :)

    I think lots of fish would be happy to eat baby crayfish - the babier the better ;)
