Len,
the sunbursts hassled him a bit, but not anymore. As for temp, I'm probably way too warm, at around 80*. That being said, I'm pretty convinced this was caught in shallower water, as I've not seen this fish ever offered from Bali before, and it came from a standard supplier.
Seems to prefer larger foods, ignores cyclopeeze, but happily eats arctipods, and especially hikari mysis. He's definitely found his spot, hanging sideways or upside down.
If anyone's interested I'd be happy to post progress.
