Binge
, so sorry to hear about the problems. Hope all works out.
I have had the experience of loosing almost an entire tank due to introducing two wild caught cichlids into an establish tank without first doing a quarantine. I now never assume any fish is free and clear of anything. Even when a vendor waited a week to run parasite treatment before shipping the fish out, I still treated the fish when it came in. I cant stress enough how important QT is. Ever since I have done QT treatment I have lost zero fish. For me the very first thing is doing a parasite treatment. I like to use Tetra Parasite Guard. These are the fizzy tabs and they use multiple meds. I run the full course of treatment (3 times) and then wait upward to six weeks before the fish goes in the main tank.
