Salty said:harpogarza, I've seen it the other way. I purchased a 9" jack dempsey once cuz I felt bad for it, the lfs had it in a ten gallon. Anyways I just purchased my 65 g. and quickly set it up. An old high school pal of mine had a 90 g. with a male jag who was about a foot long. I told him I would rather my jack went to his tank, cuz i'd rather start with a juvi jack and raise him up. Well i delivered the jack to him, they just stared at each other locked up and the jack crushed this 12" jag into the corner. The jack showed the jag what was up, then backed off. The jag would'nt give up he kept mess'n with him, and the jd did it again. honestly I like jacks they just have better color , but jags are very vicious looking, something about those eyes.

Gotta love that. I recently added a juvi Flower Horn to my 125, mainly so Jack and my RD wouldn't go at it so much. The FH and Jack seem to have struck some sort of temporary alliance against the RD. I put caves in for Jack and the FH, but they aint going out like that. They stand their ground against the RD, despite him having the size advantage. When I had my 3 Tiger O's Jack rountinely whooped up on them until they learned not to mess with him. Don't mess f#!$ with a JD, son!scottv said:I love it when you get a JD that doesn't like to hide and doesn't take crap from other fish....making use of it's capability....they have nice sets of teeth....some get a nice strong body with a narrow head like Jags too.![]()
My little guy is like that! It goes nowhere near caves and is always dark. Just like my old one I had when I was 8 years old...always swimming about. Can't wait to grow this one up too.
