I would get some black worms and pack them full of food until you get the fungus treated first.. when they put on some weight and seem to be a bit more stable, then treat for parasites.. rays can live with parasites for quite a while especially if you are 'free-feeding' live foods like worms. Its better to let them be stable healthy eaters and have good water parameters and no other underlying issues, then you will be less likely to have issues when doing a parasite dose..
I hear its also good to 'fast' during parasite treatments (ive seen this with reptile treatments?) as you want to clear the intestines of any food sources for the parasite and allow the medications to complete clear and eradicate.. I would feed up until the day of treatment and then dose with a 4x dose of Prazi and not feed for 3 days.. then repeat the cycle as many times as I felt was necessary..
