My new Dovii male has some anger problems. He's only 3.5" maybe 4" but takes on my 20" Pleco who dwarfs him. He tries to pull the pleco away from the cave that he now calls home. It's hilarious, a tiny Dovii beating on a giant. The Pleco is fine though he doesn't really mind but once and a while he will chase the Dovii around. This is my first Dovii and let me tell you VERY impressed with aggression. My ballistic Midas may have a competitor but thats a long shot... I don't think any fish will come close to his (midas) aggression.
