Mr Clown Loach
I had my red tailed shark and 4 rainbow shark. All of them are slowly dyeing off from some sort of illness while other fish that are in that tank like my cory cats are unaffected. I have one shark reminding and its not doing well, so is it possible that they have some sort of illness that only effected shark please reply with any input. ph 7.0 a 0 nitrite 0 nitrate 5 tank is fully cycled and all shark have no wounds from fight or etc.
