Feeding an Open Brain Coral

I bought a green open brain coral (Trachyphyllia geoffroyi) this week and was told by my LFS salesperson to feed it mysis shrimp or krill. Problem is, I have a cleaner shrimp who loves taking food from corals. So, she recommended I put a tupperware container with holes drilled through it to allow the brain to eat and "breathe" in peace and not let the cleaner shrimp steal the food. However, tupperware floats and I can't drill holes through a glass container.

Any suggestions?

I was also told that shrimp and krill is only 10-15% of the coral's diet and not a big deal if I don't feed it. I'd rather feed the coral and make it happy but is this statistic true?

 

Cut a 2 liter soda bottle in half, and use the top half. Its not nearly as dense and will not float. If its small enough of a frag, you can do the same thing with a normal water bottle.

 

Agreed -- I have to feed my plate and open brain corals in a cut 2-liter soda bottle. While the food loss to fish and invertebrates is significant, I wasn't too concerned until the green spotted puffer tried to bite food on the plate coral and actually bit the plate coral itself, leaving damage.

 

Or you could not feed it at all. I dont feed mine anything and it doesnt seem to mind. Pics?

 

I second the not feeding at all. You're more likely to add extra nutrients in your tank and you'll be feeding the algae in the long run.
