Feeding live freshwater crayfish, bad, good? Really bad?

Greetings oh respected scholars of Teuthology,

I come before you humbly today to ask thee of a question.

I know this probably a big no no, but just for sure I wanted to know. Can I feed the octopus a crayfish that I caught from a local river? And how about crayfish from the L.F.S.? I would also like to hear your opinion on salt water crabs, for example, emerald crabs, wild caught small seashore crabs. (to tell you the truth I sort of want to see some action, and the other students are pressuring me to do so, but I still stand true to the fact that the octo's health and well being comes fist and foremost) I used the very convenient search, but could not find anything.

Thank you very much

the "standard response" is that freshwater animals are like candy: the octo will enjoy them, but they don't have the proper nutrition for a long-term healthy diet.

Standard response #2: Freshwater fish from a fish store may have been medicated with copper, which is fatal to an octopus.

That would be their standard diet. There's nothing wrong about enjoying watching natural feeding behaviors- especially when you go to the trouble to feed them a natural diet!

I fed my aculeatus live freshwater crayfish every 3 days and he lived (with me) for 9 or 10 months. It's the only thing I fed him. I work at the LFS around here, and I know we don't put copper in our freshwater tanks...so I guess that knowledge is to my advantage. Ask if your LFS uses copper with the feeder tanks.

I heard if you really want to see some action, try some salt water shrimp. Some octos will eat them and some wont, but they are fast and there pretty cool to watch if your octo will catch them in the daylight.

Freshwater crustaceans seem to be fine while freshwater fish are not. Its got to do with the fatty acid content. There is a link to a study in the last thread this was discussed.

The problem with LFS fish, mostly feeders, is not that the LFS treats them with copper (some do, some don't) its that they are treated with copper/other bad things for cephs at the breeder/wholesaler almost universally.

Of your list of choices, by all means feed the local crabs and suggest to your over enthusiastic classmates that if they bring in a few live crabs, they can feed one to the octo :sagrin:

If fiddler crabs are in good supply, they are probably the most universally accepted, most dietary suitable and most action for the money food you can provide.
