[Delphinus]

Seems fine to me. They need to eat but they don't need to eat a lot. If you're happy with it (and it seems to be doing well) you could just continue on. Alternatively you could probably easily get away get away without the silverside and just feed weekly. Silversides are a little bit messy, kinda oily and I've heard stories on RC of people losing, or almost losing their anemones after they suspected was "a bad silverside". Usually those were in reference to carpets though, I've never heard the same thing said about a BTA, but then BTA's are more resilient overall so it's probably not even a concern.

I tried feeding various things to anemones including mussels, clam, fish meat, mysis, shrimp/prawn .. I found with BTA's they tended to eat shrimp with the most gusto. Fish with less gusto and shellfish the least (in fact would usually get spat out the next day). It seemed to me anyhow that BTA's were preferring shrimpy food. Nowadays I pretty much just give mine mysis and/or krill.
