They are EXTREMELY intolerant of most tropical fish parasite treatments on the market. You probably will not even get away with a 50% dosage as with some scaleless and sensitive fish species.
They are not very salt tolerant either, but it is my understanding that there is only one parasite that they carry that can tolerate tropical fish temperature ranges. I am by no means an expert, but until someone more knowledgeable chimes in, I would think that your best bet is to quaranteen them in 78 - 82 degree F water for a week or so. Good luck!
