Out of the choices that you have provided that I have experience with, I would say dovii. However, I don't know about umbie, and beani as well as istlanum are supposed to be some mean SOB's.
lol we had a convict pair that were like ures male was 6" female 4" then they thought they could own the rd... he owned them in seconds.bucyouup68;2142194; said:I have a breeding pair of convicts that would own just about any fish on that list.

but irregardless, the one with the worst rep is the dovii of course, but i have a feeling it is because of the size and power, not aggression.
very true, we used to have the aggro gold saum he was about 8-9" really aggressive just loved to terrorise tank mates all day long. then we got the RD and first of all as we put the RD in the tank he was biting it a couple of times and removing a couple of scales.. then the RD had enough and well... that was the end of the Gold saum..Dmaan.;2142623; said:yeah well i find your post kinda stupid
green terrors aren't consistantly aggressive like dovii, red devils or umbie's.
and yes you're right, every once in a while you will come across an
aggressive g.terror or oscar or something but i bet any money put it against
a dovii or red devil and it will be punished for standing up against either.
