I need help. My tank has a columnaris infection and it's going through my tank like crazy. I've lost nine fish in a week or so and I want to save the others. Over night I lost three, only one was showing signs of the infection. I've tried the Interpet anti bacteria and the anti fungus and neither have had any affect (At first I thought it was a bacterial infection as one fish just dropped with no symptoms, I dosed the tank with that first. Then I thought it was cotton mouth, hence the anti fungal). Everything I've googled has come up saying I need to use antibiotics, but under UK/EU law, the products used in the US to save their fish cannot be imported legally. I need something I can leave in my tank as the symptoms are showing up an hour or so before they die, before then the fish appear healthy and normal. No hiding, rubbing themselves on things, no weird patches on their bodies etc. So far it's only going through my female bettas (I've lost six of my nine) and my danios (I've lost three of my nine). The other fish, loaches, otos, plec, rainbow fish, shrimp and snails seem unaffected.
My tanks parameters are:
Ammonia 0
Nitrate 30
Nitrite 0
Tank is 40gal long, low tech planted tropical. I've dropped the tank temperature down to 22c. Done water changes before dosing the tank with meds. Removed the required filter media etc.
Please help. I've had my tank seven years. I've lost fish I've had for years and it's devastating to have to keep burying my little buddies every other/day.
