Feeding A BTA

[RicePaddy]

I have a BTA which is about five inches in diameter. I have been feeding it some frozen (Thawed) brine shrimp once a week. The tentials are stringy and do not seem to be taking the bubble shape. Also it seems to shrink at night until the clown fish works it back open.

Is brine shrimp the proper food to be feeding my BTA and is once a week enough?

Looking for any and all suggestions/advise.
