I feed mine chopped squid but if you have an established aquarium, you do not really need to feed them. I feed my fish 2 or 3 times a day and the anemones get some from that also. What they really need to survive is light.
You can try the ghost shrimp or the crayfish as long as the pieces are pretty small. If they do not like it they will just spit it out.
Very nice!!
You may want to check your phosphates. Looks like you have a good crop of hair algae started and if left unchecked it can become a problem.
the hair algae start growing after I change to led (onyx rapid led) last week. Also the live rock began to show more colors, I really don't expect it to be this fast.
You can get rid of hair algae by lowering your nutrient level via water changes.
Some of mine will grab the pellets and some of them won't.
A scrubber should help. I just bought 2 myself.
I feed my Inferno BTA krill. The krill comes in a small pack in the freezer section of the LFS. I have had the Inferno for several years. I have had multiple natural splits. I feed it every other day. Some might say it's too much but it has worked for me. I have two Rose BTA's and they also eat krill. They will accept other varieties of food including Fauna pellets. I wouldn't try and feed food that is not from the sea or designed for salt water inhabitants.. +1 on water quality. BTA's need good, stable water quality....
