Honestly, if it were my fish, I'd euthanized a blind fish.
I've considered it, mostly worrying that if both me and my boyfriend are out of town for a while, who ever takes care of the fish won't bother to make sure Plinko eats and the little guy starves. Or feeling bad that he spends his whole day upset running into things or getting stuck in plants, and scared when unseen fish go after him (bn pleco is incredibly territorial).
Up until this, I'd thought he was doing much better - swimming, eating well - but now I'm not sure what went wrong.
I'll try the Maracyn Plus + Melafix + salt treatment for a while and keep my fingers crossed.
If I'm wrong on any of this, please let me know.
Thanks
