They seem to like sps light. And they will hide under a rock or move if it’s too bright…where an acro will just get fried!Have you ever measured your PAR in any of the tanks? I'm curious, because everything I've read says BTAs need "SPS level" light, but most people I ask have them in 150-ish PAR or less.
When I did my initial light setup, I used a PAR meter and saved "schedules" (AI app) for my tank at 100, 125, 150, 175 and 200 PAR (measured right in the middle of the cube). It's a 10g cube, so there's not much room for them to move closer to, or get away from the light.
Now that I'm ready to add my first anemone, I'm wondering where to start.
