I would say yeah but once it gets bigger, then you will start to have aggression issues. That umbee will start challenging the pecking order. Even though your Midas is not aggressive, he might start to show his aggression once the umbee starts challenging him. Umbee's are an impressive fish to add to any collection. They need and do very well in large aquaria. Its an awesome sight seeing a 16in + umbee swimming around in a large tank.
