So one of my female GBRs has been displaying very low energy for a few days, and I'm getting concerned at this point. She's been eating sparingly, and just generally spending most of her time in very low-current areas. My immediate guess is that it might be a swim-bladder related issue, given that she's developed the habit of resting at an angle. Sometimes she's sorta leaning to the side, sometimes tipped forward about 45 degrees, etc. Nothing too major. Until about 5 minutes ago. After a couple otos went dashing past her and nudged her out of her spot, she did swim perfectly upright (no leaning or anything), but only to get to another low-movement spot on the bottom, by some driftwood: Peas are definitely on the menu tonight, I think. Any other thoughts? I first noticed the low energy a little under a week ago, so whatever it is certainly isn't terribly fast acting.
