Hi there, I'm hoping for some advice on treatment of my fish. I have a golden severum, fit and healthy, had him for months. He is in with two fish which have not been in good condition from when I was first given them. A green severum (fin rot), and a snakeskin gourami (white patch on side).
I have the three fish in a 160 litre tank for treatment. I have dosed as per instructions as best as I am able.
Day One - Three capsules in tank
Day Two - Three capsules in tank - gourami developed some pits on his head.
Day Three - green severum looking very sad, sitting on bottom of tank, gasping. 50% water change, rather than 25% change - she looked much better
Day Four - Three capsules in tank
Day Five - Gourami sitting on bottom, labouring to get to top of tank for a breath. Lowered water level so less effort for him, to approx 2/3 of previous. Two capsules added. Gourami's patch on the side of body looks like its peeling. Green severum looks well.
So what's happening here guys? Is the treatment making my fish sick? Am i doing something wrong with the dose? Is the patch on the side looking worse because it is getting better?
I will be tempted to do the second water change at the 12 hour mark this evening rather than the 24 hour mark tomorrow as its almost like the fish can't handle the second dose. And then do I treat a second round?
Your advice please,
Sam
