I noticed Cinder's bubblenests kept getting smaller and smaller this past week and I was baffled as to why until just now I noticed he's got a tiny hole in his dorsal fin. I am wondering if he might have poked it through on one of his fake plants, but I dunno... what should I do?
I've never had to all-out treat finrot or torn fins before. Help?
He's otherwise swimming normally and eating okay.... he 'sleeps' a lot more than usual, though in his other silk plant.
If it's a tear from a plant, I just need to know the best remedy to encourage fin growth (and I'll take care of the offending plant; I think I know which one it is).
If it's finrot, I need the best solution quickly!
In the meantime, should I do a 100% water change just to be on the safe side?
