It's at 50 par. Is this a too low par problem or something else? I've got three around the tank at similar par, and they all look like this. They were flat and normal looking orange ricordias when I put them in a few months ago.
I have had considerable success with ricordia... some are good at 50 par however most I've had (especially orange) are better at 100-250 par. Yes 250 if they are allowed to migrate up to it on a rock slope.
If you can ricordia do really well mounted on the side of a rock. That way they move up or down accordingly.
In 20yrs this has officially been my favorite system. Hopefully in several more it will officially be my longest successfully running reef display. www.Slide-Loc.com
