a couple of months ago, i purchased 4 dwarf gouramis, 3 female, 1 male, after about a month the male developed what looked like WOUNDS on his body, like he had been thrown against something, or was attacked by something. then he died. this happened to two of the females one by one all with the same reult. the final dwarf has no wounds and looks fine. but i would love to know what this was. sorry i could not get a picture. the inhabitants of the tank are in my sig in the 20 gallon high. any ideas? and yes the tank has been established for over a yr now, and yes i checked the water stats they were and are fine
