I bought a BTA almost three months ago. It was three times bigger than it is now and it was more colourful. It refuses to eat anything. I have another BTA and that one is doing great. It eats everything I give it. I have been target feeding both of them brine shrimp, mysis shrimp and now I am feeding them sliversides. My elegance coral and the health anemone eat them but the smaller one doesn't. I don't know what else I can do to bring it back to health. I also have frogspawn, torch and an acan coral. They are all doing great.

It isn't sticky.... I can' find the sticky on how to treat nems, I read on another post that it is at the top but I can't seem to find it.

I would boost up the SG to 1.024-1.026. Anemones do better with a little higher SG. How old are the bulbs in your fixture? May be time to change them. You don't need to feed it, it's most likely catching particles from when you feed the tank. Also, there have been numerous cautions on feeding silversides.

I'll boost the SG. The bulbs are only 3 months old.
