Just want some advice regarding my clown loaches. I've been medicating them for ICH and using aquria-sol and so far everything is going good with only a few spots left on 1 or 2 loaches, but I've noticed on of my clown loach looking really weird, mouth is open all the time and the eyes seems huge and looks really weak and lazy. I've seen this before and lost 1 clown loach with the same symptom and it died a few days after. Also I have small ones that look really skinny and haven't gain any weight inspite of them eating like pigs..Can anybody tell me what to do, I don't wanna lose this one cause he's the biggest one I have about 2.5 inches...My water parameters are good: Ammonia 0, Nitrites 0, Nitrates below 20 ppm, temp 86 degrees, ph 7.6....any advice would be great...thanks....
