I agree with Toddrtrex....
"When ever I feed the anemones, I just give a little bit to the shrimp first, that keeps them busy"
I do the same - I have 2 GBTA's, 2 cleaners, and a fire shrimp all in the same tank....... Twice a week, on anenome days, I will feed the fish, and then 10-15 min later I am ready to feed the 'nems.......
I currently have no clowns in the tank to protect them - and 5 months ago or so my BTA split, so both are baseball/softball size... I feed the GBTA's a piece of shrimp or squid, plain m&m size - tenderized/beaten up - and I will also give each shrimp a chunk of the meat - small raisin size - untenderized - to keep 'em busy..... The shrimp are used to all this and quickly come to my hand to take the food. They are also greedy and will be too occupied with their own chunks and breaking it down - to worry about much of anything else.
Within 10-15 min, my 'nems have completely ingested the food and their mouths are closed back up..... also, the cleaners and fire are too full at that point to care.
It took me a while to figure this all out..... a much better "cure" than playing underwater polo with them.
