Glad to hear there's such great improvement! I think you made the right call with the M/M2. I know you'll keep watching him, but congrats. thus far!
Gourami recovered, the tank appears otherwise unaffected (thankfully). I'm still rehoming 2 of the golds though after getting to see how dirty they really are.
