plz help me i got this stingray for almost a year,sudntly i found that he ave strange white bubbels on top of him (the temputure is 27c and he is still eating as usuall )
Looks like a fungal infection. I would do a 50% WC, add salt (not adding the crystals directly to the tank) and hope for the best. Looks as if the disc is curling which is very bad. If it is eating that is good.
