Hey guys, I'm having some minor problems with my 2 rays and was hoping you guys could help, i have a 220g tank, with one SP.Peru (6"), one motoro (8"), two 7" pbass, one 10" silver aro, one 17" fire eel, one 5" datnoid, the tank has a sump, and my ammonia is 0, nitrite 0, nitrate around 40 ppm, although a few days ago i noticed the SP. Peru had a little mark on the bottom of his disc, that kinda looked like a pimple or something, and i have no clue what it is, or how to get rid of it, but recently i noticed the front of both of their disc's, were slightly darker, not alot but darker then normal, and was rough like sand paper, and it wouldn't go away, then 2 days ago i noticed the motoro, had a black mark on the corner of her mouth, which i think is fungus but i am not sure, i didn't have enough prazi to dose the tank yesterday and the lfs was out, so i dosed with melafix, and so far (not even a full 24 hours) i don't see any difference, now today i picked up some prazi, but don't know what to do, should i dose the tank with the melafix still in there, or should i put my carbon back in and wait a day, then dose with prazi?
any suggestions are greatly appreciated
Thanks
