First time poster here found you guys while looking around for what could be causing my issues.
I set my tank up while looking for fish and cycled it and after adding fish 2 months ago it started a 2nd cycle and this is where it’s going crazy on me. In addition to what is posted on my signature about my tank I had 2 butterfly koi in the tank as well and they began to get patched of what looked like mucus on there bodies.
The cycle of the tank finished and cleared up good reading from the water testing kit in about 3 days and the fish were still sick. At the recommendation of the pet store I got some anti fungal meds and the fish died 24 hours later. Everything seemed fine till 2 days ago and my current yellow and orange ogon began flicking at rocks.
It now looks like the orange one is suffering from a rapid/aggressive case of fin rot and the yellow one would rather want to live on land then in the tank at this point(hes jumping at of the top of the tank so often and with such force he now has an open wound on the top of his head). I’m using aquarium salt and a medication called QuICK Cure. That is supposed to help with all of the above symptoms and it’s going on day 2 of the treatment without any visual results anything anyone can think of that could help me out?
The fish are all at or near 3 inches waiting till they get about 5-6 before I place them in the pond. API fresh water master kit is showing everything is good ph is a hair base but other then that perfect water is crystal clear.
