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

Do they treat freshwater crustaceans and snails with copper? Wouldn't it kill them with high enough levels?

We've had big discussions before on these forums about crawfish and whether feeding only freshwater food will harm your octopus. The conclusion was that you could feed crawfish, but more as a treat and feed saltwater food such as crabs as the main food.

Crawfish are essentially freshwater lobsters, so they have a lot in common with the saltwater crustaceans we feed our octopuses.

Interesting that your aculeatus survived so long on only freshwater food, forever27. Were there amphipods and other things he could eat in the tank?

I also mentioned at the time that some of the crawfish are as large as small lobsters (at least they are in Texas!). Choose females and smaller crawfish so your octopus doesn't risk damage from the claws.

This "conclusion" still seems odd to me considering the number of ceph hatchlings raised on PE Mysis.

Actually, come to think of it, that's a real possibility. When he was in the tank I never saw amphipods, but now that Lennon's in the tank I see them. I still think that crayfish aren't a bad staple diet. The downside with them is that they die quickly in saltwater, so if your octo isn't already eating aggressively and its waiting until the night to eat...they may not be worth it. And with the males, I just pulled off the claws before I fed them to him.

More interesting, perhaps is checking the signs carefully on the fresh raw shrimp available at your grocery. At Public's in Gainesville, I can get either Aquacultured or pink wild caught. The butcher said the pink wild caught were raw and I bought a couple to examine them. I have NEVER seen an opaque raw shrimp and believe these are partially cooked as the meat is not at all like raw shrimp. The Aquacultured are fresh water.

There have been a couple of attempts to locate the fatty contents of fresh vs saltwater crustateans but no one has come up with numbers and a translation to what the numbers mean for a saltwater animal's diet.

Wow, thanks guys this is all valuable information.....keep going my brain is soaking it up......oh just to tell you guys I caught a chromi (with my bare HANDS!) from the sump and put it in a glass jar and put it in right next to the octopus, he was so excited to see some real game his head was bobbing up and down like mad. He didn’t wait a second to get inside and liquefy his juicy flesh, mean while the whole school is witnessing a brutal killing, something they thought was something that national Geographic’s couldn’t beat. The fish put up a noble fight, but in the end, the brissle worms had the last laugh. Gladly he ate the whole fish, except some sink, considering the fish was the size of his mantle. Then for some very strange reason right after eating he completly slaugtered a turbo snail. He never bothered them before. He ripped his guts out and proudly showed them off by jetting around with them. Then he discared it to brissle worms, not even taking one bite. Killing to please? Killing for pide? For fun? We will never know, except you guy jessgifnerrgah ah ahgah!

Just wanted to shared that with some octo freaks
