I am starting a 135 gallon discus tank and want to pair them with some Geophagus Sveni. Of all the Geos, these apparently stay a little smaller (7 inches?) and have really nice colors and fins. Ideally, I would find a group of 5 juveniles around 2 inches or so. Has anybody had experience with these and does anyone know where to find them? I have looked online and other than one ebay seller, I can't seem to find any. Thanks.
