nolemite said:This may be the case in your tanks, but I think in general there are differences to be found in behaviour even within the same species. So while your Dovii is pretty sedate and your umbee a terror, I think it's entirely possible for someone else to have a dovii that's a terror and an umbee that's gentle. Ask arapaimag about the behaviour difference between his two dovii.
Moral of the story, I don't think anyone can conclusively say that a dovii is badder than an umbee or vice versa. In terms of looks, well that's subjective. One man's junk is another man's treasure as they say.
I have both Dovi and Umbie's and really enjoy them both.
I have a 8" Dovi and a 20+"Dovi. They are both males. They have completely different personalities.
I found that all Dovi's are more aggressive the SMALLER the tank they are kept in.
My large Dovi I got as a 2 year old and have owned him more than 10 years. He generally is very peaceful and believe it or not a very good community tank fish. He is in my 15k.
My smaller Dovi was given to me a few months ago by DJ's Tropics because he killed every fish he was housed with. I put him in a 180 with a baby red tail (SA) about 14". The red tail was bought in May at 2". The Dovi almost killed the RT in a matter of minutes.
I moved the Dovi quickly into a 90 with a 22"lungfish. In less than an hour the Dovi had ripped the lungfish to a point close to death.
I moved him into a 50 by himself for a few weeks.
Because I was removing several small tanks I decided to put him in my 50k+. Nolemite put him in the tank. The Dovi within seconds attacked and bit the alpha male Oscar in the tank. Within One week he killed all four sub dominant Oscars in the tank. All of which were 10 inches or more.
The personalities of each fish even within the same species differ just as they do in humans.
personality and on top of this, they kill anything they can bite into (obliterate
). But for you to truly understand why anyone would go to great extreme (money in your case
