That should be enough lighting, but still on the low side for a BTA...That being said, I've kept them under lower lighting and did fine. Make sure(even if the ph's come with intake guards) that your anem has no chance of being sucked in. Right now someone is talking in the Anem&clown forum about their BTA getting sucked in and is now stuck inside their powerhead...it is a fate I wish upon no anem and noone's tank with an anem in it...
Might want a little more rock unless it is very porous.
I feed a whole bunch of different foods to my anem. Personally, I think that boneless foods(non-vertabrate, non-fish) are best as the bones can get stuck and choke/tear the anem internally. I like inverts, mostly ones bought at a grocery store(squid, scallops, oysters, clams, shrimp, etc) and mysis soaked in selcon and garlic to gain nutrition for the food. The most logical way I have seen to get it to the right size(wilkerson talks of this in her book) is to freeze the food whole, grate it with an unused cheese grater, refreeze that, and repeat...I like grating twice to get good sizes that my nems, clowns, and just about any LPS corals can eat. After grating, additives can be added(selcon, coral vibrance, garlic, spirulina, etc). Then just form it into a nice thin sheet and freeze. When you need food, just break it off the sheet. Or you can do the small ice cube tray method of freezing(not really ice cube tray, but to that same effect), so that the pieces are chunk size already...I personally like the flat sheets.
Voila!!! $50 of fish store bought food for about a quarter the cost.
