ooh, good thread, as I am still getting my 20g community up and running. I got a dwarf gouramie on sunday, and today (Thurs) he has a patch of somthing on his side behind his gill. he is eating and mostly acting ok. To me it doesn't look like fungus, it looks more like whitish/peach colored flesh, and there is a red spot underneath it as well(it's very small). I don't have a hospital tank. All the water tests have been good all week, so I don't know. Any suggestions?
