Interesting you should mention that Old Yeller Tang...Dwarf angels do have a reputation for liking the taste of T. geoffroyi ...but I've had my coral beauty in with mine for well over 18 months now with absolutely no problems.
*knock on wood*
I have a question. I love my green brain, it's beautiful. It always has feeder tentacles out. Even right after it eats they are still out. Is that normal?
