I new to the forum and I am very happy to have found it. My wife and I purchased a fish at our local fish store that was a trade in. I don't know if it's male or female nor do we know what tha heck it is. It's about 10" long and gets along well with all the others in the tank. We have 1 large oscar(8"), a small oscar(4"), 2 arowannas(14"), a redtail cat(8") a large pleco(16"), 3 tin foil barbs(5), upside down catfish(6"). Please help us classify it.
