Roses are red, .....

[Delphinus]

Nice catch, Brad! Definitely some jealousy happening over here...

BTA's like to attch to a hard smooth surface, but they like their pedal disk hidden from intense light. So a crevasse, cave, or overhang is usually preferred. Their tentacles will want to be out in the current and out in the light.

I'm not entirely certain I agree about placing an anemone into a low flow area. They like flow, they need flow. Definitely not a powerhead output though, it will move away from that if that's what it's getting. If it has problems attaching to a rock right away then maybe, but if that's the case, you got problems... I have never, never had a healthy anemone not immediately attach to a rock. Not saying if it doesn't attach right away that it can't recover, that's a different story. But if it's healthy, it will glue itself on pretty much right away. And if you get its placement right, it will likely never move except for shifting this way or that slightly. The only times I've noticed mine move more than a half inch have been just immediately prior to a split.
