BTA - white stuff on tentacles

Sorry hit post before typing the question- this BTA was healthy for more than a month. This happened after it ate some shrimp. Since then, it has expelled its poop a few times. It has also been moving all around and once tried to get to the wavemaker. It is now releasing these white stringy stuff from its tentacles. I checked water parameters at the LFS every week and they said nothing is out of whack. The tank is about 4 months old and has a couple clownfish, inverts, a hammer, frogspawn and a zoa frag. There is an RFA and that is looking healthy. I am just not sure what is wrong with this one. It has not expanded fully ever since it ate that shrimp. It is either balled up or walking around with its feet all balooned up. Anyone care to guess what is going on? Thanks in advance!
