Hey guys, my gold nugget pleco has white patches on him which I IDed as probably a fungal infection which I've been treating with primafix for two days. He hasn't eaten in a while so his belly is a little caved in. What I need to know is if it's okay for me to do a big water change mid treatment? My brother threw 10 algae wafers in the tank over night and now it's cloudy. Will changing the water over stress him? He just hangs out behind the filter all day so I'm a little concerned right now.
