I've had mine for about 4 to 5 years now. Great fish and with those scales they are unphased by other more aggressive fish. I had a JD and Nile Tilapia both in a tank with it and it just goes along on its almost never ending hunt for food. There are 4 different types of hoplo that I know of. Port (what you and I have), Black Port, Salt and Pepper/Spotted and the lighter colored Clay Hoplo. I'd keep it. I wasn't crazy about mine at first but they do have great personality and like previously stated they are damn near indestructible.
