Bubble tip concern

[RTD]

This BTA has been in my tank for about 4 months now and always looked really healthy…Hosted by a clown. A few weeks ago it moved to the back, bottom corner and has progressively declined. Haven’t changed anything as far as flow patterns or rock locations. Water parameters are consistent and in good quality. I feed it a piece of silverside every week. What’s this things problem? The pictures posted are from about about 2 months ago and what it’s now become.

Id stop feeding it for a while and let it be for a few weeks see if it improves at all, it should able to survive on just the lights on your tank. Some of the people on here should be able to help you treat it if it ends up needing treatment.
