55 gal.

yes jd i ment, so im trying to level out the aggression and make it so know one is the true bos
 
Good stuff...I had a 55g with an FM pair and an EBJD - the male FM was the boss, but the EBJD just ignored the FM. The male FM eventually killied his mate though. Was quite good watching the EBJD lurking when there was FM fry.

With a 55g you could do:
1 JD + FM pair (or similar 5-6" sized cichlids, 2 different species or pairs)
1 Sev (SA cichlid though) + 2 mellow 5-6" cichlids
1 Sev + 1 JD
A JD pair
 
so my idea ist realy that bad
 
No, but I'd fear the JD would be the boss. Sev's are quite mellow, and can be housed with largish community fish - you couldn't do this with a JD. The FM wouldn't be the problem (although my male one turned crazy, flaring at my EBJD regularly).

Have you considered an EBJD, as opposed to a regular JD, as they're a lot more mellow? Then I could see your wishlist working better (although they are quite sensitive until larger than 3-4"). They are quite pricey too though...
 
...or a female JD. They usually top out at around 7-8". Males would be too much for a 55g (size and aggression). This is concerning standard JDs not the Electric Blues.
 
it would proly be a eb
 
i might go with a nicuraguan, or a savini insted to make lets fighting, ohh and i got the tank today
 
Females of either of those should be OK - the male nic gets a tad large, and the male sal a little boisterous
 
Male Salvinis can be down right vicious (especially when breeding)...as are the females (when breeding). A 'lone' female would work, though they can be quite shy/skittish.
IMO, Salvinis are much more interesting and colorful when kept as mating pairs; but that leaves not much room for anything else.
