Okay, I got this thing at my local pet store and was told that it was an upside down catfish but it doesn't look like the pictures I found of one. It is also agressive toward my swordtails. It is 2.5 inches long and it is completely black with 3 tiny pinhead sized white dots along the sides. It looks like a catfish with the whiskers and body type. I looked through the photos on many sites and I can't find a match. I'll try to get a pic on after dinner. I was wondering if it was a black catfish (trachycorystes trachycorystes)? Does anyone know anything about these?
