Hey guys.. I want some advice.. We set up a 10 gal QT tank 6 weeks ago. Added 2 fish to it, a clown and a tomini tang. We observed for 2 weeks with no meds. Then noticed weird black spots on the tomini so I treated with Paraguard for 3 weeks. We did religious 2-3 gallon water changes every other day and tested water parameters like crazy. Everything was fine. The tomini tang ate in the morning and then died several hours later. This was on the last day of Paraguard treatment with no sign of illness before. Two days later, the clown died. I have no idea what could have caused their deaths since all water parameters were good. I had to change the salt last week bc my store was out of the usual type I buy. Could the change in salt have killed them?? After 5 weeks in QT, I thought everything would be fine. Now I'm devastated. Let me know your thoughts. Thanks everyone.
