how do you guys quarantine your sucker catfish??
I made a mixtake a while ago and put 2 Gold nuggets plecs straight into my discus tank. Within a week I lost 8 discus to the so calleddiscus plague.
The best way is to imo is to put them on their own in a small tank with anti paraite control for a couple of weeks to kill and external parasites. They add carbon filther do massive water change and use a complete course of interpet no 9
beofre adding them to the main tank.
Follow the discus quarantine procedure,
Works just as well on suckers,
