What's going on with my RBTA, it's been like this for a couple weeks now. If I hold a piece food over it, it will bubble around it and seems to be eating it. That's the most I've seen it open in the past few days, a little bigger than a 50 cent piece.
Tank parameters all look good,
SG 1.025
ALK 9.5
CA 395
Mag 1200
Po4 .04
Temp 78
Looked like this a before this started.
