i saw that ad somewhere too and i did think the same, i was a bit like huh?? although community can mean lots a different communities some people won't read into it and prob just whack them in with their neons hehe
In some situations pictured in this post jaguar cichlids an other fish can work. I have tried in a 6ft and a 8ft and the male beat the hell out of the tinfoils and central american cichlids. I found the fry aggressive at 2" the attack bigger convicts.
By the way thats a nice trimac you have got there... in that pic... and your jag is stunning.
I also thought the price was a bit high.. my lfs sells them for 3-4 quid at that siz.
Jags are not that aggressive, or what iv seen of them
i have had jags in with other fish with out any probs (apart from my breeding female)
in this 4x2x2 tank i had a male jag of 9inches living with -
4x pictus cats
1x m.pim same size as the pictus
2x small cons (whitch you can see at the front of the tank)
and some plecs
