what would be the preferred way to treat a spiny box puffer for ich and velvet. Puffer has ich but not velvet but I would like to irradicate both. The manager at my local petco calls me when she has fish on there death before/close to it and gives them to me and I attempt to treat them and keep/resell them, I’ve gotten several purple and yellow tangs aswell as a ton of others but never a puffer and I’ve never had to treat a puffer before. he has been in a qt tub for two days now to adjust before I start treating him. I know that copper isn’t preferred for them but I have cupramine if anyone thinks it would have a success at working and if so what ppm should it be ran at and how long should I ramp it up to that ppm as I’ve read .35-.40 would be preferred for puffers with cupramine but I’ve also read there isn’t a point if it isn’t at .50, the meds I have at my disposal are cupramine,prazipro, kick ich and rally, metroplex,kanaplex,neoplex and focus. he is eating and behaving normally just has ich and is a bit skinny. Any advice helps, as I stated he has ich nothing else as of now so I did not attach pictures since I know what we are dealing with.
