I have other acans in the tank and this acts differently. I've shown a few other people this and acan was never mentioned. Any other possibilities?[attachment=65552:name]
The entire frag is about 3" x3" so I would guess about 1" per polyp. It stays closed all day until I target feed at night and it opens electric green tenticals. I won it in a frag pack at reef ed and cannot remember from who or what he said it was. Thanks for the help
Based on polyp size of 1" im ruling out micromussa, its gotta be an acan. Mine tend to like low light, you might try moving it to a low light area and see if it opens more during the day
