Kale has popeye. No swollen belly, but some of his scales look...rough? Raised? Sharp? Not a pinecone, just...individual scales are visible.
So I've had him in a 1 gal qt tank floated in the 10g, and am considering moving him to his own 3g so that him and Seiya stop bouncing stuff back and forth. At this point I'm glad I got individual 5gs for my new boys later.
Added about 2 tsps/gal of espom today...see if it helps. If not, may treat with meds.
