Hi,
I am having some problems with my fish dying in recent weeks. Over the Christmas holidays I was away for a week and a half. I had someone come in and feed my fish for a couple of days but when I got back a couple of my fish were missing. I had a rubbernose pleco and a zebra loach die. I also noticed som mouth fungus on my rainbowfish but not serious amounts of it and no fungus on the body. I did some tests and found my nitrates were quite high so over the course of a few days I did several 30-35% water changes to get it back under control and then resumed my weekly water changes. The rainbow fish started looking a bit better. My nitrates never rose above 40 and were generally in the 25 range since then. About a week and a half ago my red tail black shark died suddenly. She seemed perfectly healthy and then one morning I woke up and she was dead. I started treating the tank with a product called Fungus Clear.
Then a few days ago I found another zebra loach was dead. So I started treating my tank with Maracyn. On the second day of the Maracyn treatment I had my 3rd zebra loach die. A few hours later I had a clown loach die. All of these fish seemed perfectly healthy before their deaths so I am unsure what is causing it. The only fish showing any kind of issues are the rainbowfish with mouth fungus and one bristlenose pleco with some body fungus. All symptoms of columnaris.
I should add that I also have 2 3-spot Gourami's who in the past several weeks have been hiding a lot in a large PVC pipe I have in the tank. This is unusual behaviour and they are a bit skittish but they seem healthy otherwise (no physical symptoms).
Does anyone have any idea what is causing my fish to die? It's a mystery to me because the ones that appear perfectly healthy, active, eating well, and behaving normally are the ones that are dying.
