Hi all, I was wondering if any of you ray keepers have ever dealt with ich in a ray tank or pond. A customer has 1 small P. Hystrix in a tank with several cichlids and a catfish. She says the catfish has developed some small white spots on his body so I thought Ich. I feel that I cannot reccomend any treatment for the Ich as I do not know which is safe for the P. Hystrix she has? Are there any Ich treatments that you ray keepers have used safely with your stingrays?
