Advice: leave it alone.

I have had a BTA after one of my splits, that looked limp and wilted. But 3 months later it's still with me and looks better now.

Questions: Does the clown still swim in it? Has it moved at all?

Even though mine looked like it was on it's deathbed several times, my clownfish still hid in it occasionally (went back and forth between it and the other one) and it never moved.

If it doesn't move it's likely just going through a "phase" much like some corals do where they just don't open up for couple days. It could also be preparing to split? Just keep attempting to feed it every week or so. Unless it goes white (expells all its photosynthetic algae) it is probably fine.

Also be sure to check your water parameters, as a high nitrate, nitrite, ammonia, or low pH, or Alk reading could be causing it?
