NANFA-- crayfish tank set up
Thu, 21 Jun 2001 14:39:55 EDT

The crayfish in one of my public tanks died. The library staff, being the
kind, sensitive folks they are, are concerned it was due to insufficient care
or diet. Comments on the set up appreciated.

- 10 gallon aquarium, natural ambient lighting only, undergravel filter. A
few duckweed on surface.

- Diet was canned crab, canned tuna, frozen peas and a couple times a week I
threw in some live daphnia and moina. A couple times I threw in small pieces
of dried cat food. Also had just put in some dark green lettuce. For some
reason, it did not seem to be particularly interested in dried shrimp. I
think I will also supplement its diet with an occasional earthworm in the
future. Would a little dried fish food be of any benefit? The staff seems
focused on insufficient diet as the cause.

- It had just shed its skin a couple of weeks prior and behavior seemed
normal until about 48 hours before it died. Then it became inactive and sat
on top of its tail.

- Since there was only one crayfish, I did not provide hiding places. When I
catch another, I will arrange hiding places this time. The theory being if
it gets nervous and can hide as it does in nature. If it feels comfortable,
it will come out.

It was pretty large as Indiana crayfish go and I am guessing therefore pretty

Any help appreciated.
