    inverts in fish tank

    are there any edible invertbrates (crustaceans, shellfish) that will live in with cold water fish (in relative harmony) or perhaps downstream (in a seperate tank before biofilters).
    Do they have different demands?
    Cheers

    P. clarkii AKA Red Swamp Crayfish can be kept in the same water, but must be spearated from the fish. It is not economically viable unless you are raising them for pets where they bring $5-$10 each as to 20-30 cents as food.

    I'm just guessing here but fresh water clams seem like they could work in aquaponics. In a fish tank they are hard to keep due to lack of food for a filter feeder.

    Also check out the self cloning crayfish (Procambarus Marmorkrebs), Not sure if you can eat them but I had to pay 25 bucks for mine and they pop out 20 to 200 clones based on age every 20 to 40 days.

    They didn't do well with the nitrate levels needed for tilapia. I'm now working with cherax quads (red claws). They seem to be a better fit.

    I've got an 8" male Red Claw living by hiself in the biofilter of my 75 gal freshwater Angel fish tank. I feed him a little extra pellets every 2 or 3 days and he is doing fine. The female is in a 20 gal tank with trash guppies. Hopefully this year I can play match maker and crank out some little ones

    Anyone using grass (also known as ghost or glass) shrimp in their raft tanks to clean up detritus and add more nutrients?

    I have worms and fresh water snails in my grow bed. Every drain cycle the fish will crowd around the water coming out and pick at the poor souls that got washed out to sea...

    They don't do well with most fish that simply gobble them up. The zoes (larvae) get picked off or trapped in the grow beds. They really need a separate system. They are well suited for ponds, but not so good for aquaponics.

    Would the bottom of say a floating raft system, with slow trickling water be good for them? That way they have a separate tank, access to the same water, and hopefully not too much water flow to bother them?

    A raft system water flow should be considerably more than a trickle in order to eliminate dead zones of oxygen and nutrients around the root of the plants in addition to preventing sediment from settling on the roots and causing root rot.
