Major Parasitic infection of at least half my fish. It all happened in less than a week. Most of my goramies are affected. I lost a Parasitic fish from Parasitic infection resulting in lowered immune system and he died from secondary infection . I tried all that I could I bought 40.00 dollers of fish medication just to try and save him (way more than the fish was worth, but he was my fish [his colors were crazy]), but my efforts were in vain. He broke out in red sours all over his body. After two days of medication for his sours he was looking better (wasn't all white actually had some color). I'm on my 3ed day treating with clout and my tank still isn't under control. If I lose another fish I'm planing on nuking my tank; my tank is overstocked as it is.
