im yet to see a dovii that could do my devil in a fight. he is the best fighter ive seen.
he used to share a tank with a breeding pair of adult managuense, the managuense bred one time, the male was 12", the female was 10", the devil was 11", he took on both the managuense, and won the fight.
he left the tank (5x2.5x2.5) half full of blood from 1 hit on the male managuense, blood was coming out of his gills.
i then divided the tank while i was rehoming the managuense. he broke the divider and killed the male and nearly the female. luckily i got there before the female was killed aswell.
