well i got a new ray in this afternoon and he has mainly stayed in the same place not moving around too much. well finally he came up to the front of the tank and around his anus and feet it is very red kinda blood shot looking. lights have been off since he arrived i did a water change last night and another today. i added salt and prazi also temp is at about 82 i also removed half the substrate so that half the tank is barebottom is there anything else i can do for this little guy? he is very small and dont want to lose him. if he ever comes up the front side again i will snap some pics, but he mainly stays put also he is not breathing hard or showing any sign of any stress or anything else. i love the kiss method so i dont want to add any crazy chems but if you have any idea of what causes this or how to treat let me know. thanks
