Feeding anemone shrimp? Sodium tripolyphosphate

I'm trying to test a hypothesis of mine.

Are any of you feeding your anemones table shrimp? If so, where are you getting them from? Are they fresh (live), frozen, or defrosted at the meat counter of your grocery store?

If you're feeding frozen or defrosted, the likelihood that it contains sodium trypolyphoshate ("STPP" for short) is high. Apparently its used to give fish and shrimp a better texture after its defrosted.

I have a hypothesis that anemones -- small ones -- may be affected by STPP. I have a pair of gigantea sharing a tank. One is 5" and the other is about 2.5" and I recently fed them small pieces of shrimp which I later learned had STPP. Both deflated a bit, but the smaller gig remained deflated and even partially detached. Both appear to be fine now, but nothing in the tank changed. I also have a magnifica in a separate tank, but connected to a central sump, that also ate the same shrimp, but is larger -- approximately 9" -- and showed no affects.

I usually feed the anemones salmon, and they never deflate after eating. I also run a lot of carbon on the system -- in the sump where the water is forced through it to get to the return section -- so I don't think it's allelopathy that's causing it.

Thoughts?
 
I have been feeding shrimp and scallops for a while. I have never seen any ill effects.

Mine is normally still frozen, from the meat counter (seafood, but same dept/spot)

Mine really like scallops more than shrimp.

Both my mag and gig don't like frozen shrimp and always ended up spitting them out. I feed strictly salmon and have never had them spit it out. I only feed them about once every couple of weeks. They both deflated pretty drastically after the frozen shrimp. Never any ill effects with salmon.
 
I feed my mag fresh shrimp, but I thoroughly rinse them in cold fresh water for a minute or two before cutting them into smaller pieces. The nem is about 8-9 inches, and I have not noted any ill effects.

I would note that I have just started feeding it however, and have no long-term results.
 
I feed my BTA mysis and LRS reef frenzy. Seems to love both.

Although, after reading PaulB's thread on feeding his tank inhabitants fresh (frozen and cut up at home) clams, I do believe I'll be doing some clam hunting at the local health food stores.
 
Although I haven't heard of any negative experiences. I am always sure to buy shrimp for my nems that do not have any added chemicals. Why risk it when there are alternatives available?

Most of the shrimp we eat have STPP. I'm actually having a hard time find any without it. However I do have access to live shrimp, but I think I'll just go back to feeding salmon.
