I just added some other cichlids to my 90 with my Jack and the first day he chased them around but has since settled down and is just like one of the fish.
Tankmates for Jack Dempsey

I have two JDs. Well 4 if you count my blue juvis. The two adults used to be in different tanks with similar setups/stock. One was vicious and tore apart anything it could. The other was a peaceful community type. Now they are together with silver dollars and tinfoil barbs. They do well, but the one can still get cranky. I guess the point is to try them out, but be ready to move them. Space is key. If the tank is large you will have fewer problems obv.
severums are very good dithers, calm and keep serenity, unless you have some wacked one.. all terquoise severums ive had, are great, held thier own, never picked fights, and my first sevs were a mated pair

I have never kept Severums before, but I am definitely considering it for this.
All your ideas are good. Pike cichlids are generally aggressive to conspecifics or other bottom dwellers, you could definitely get a belly crawler pike. Severums are great. Bichirs would be good. You just want to make sure anything you put in can put up with a JD, especially be mindful if you put in similarly sized and shaped cichlids. Other than that, you won't really know until you try, as noted.

Yeah, the Belly Crawler was the one I had in mind as I always hear that they are one of the smaller Crenicichla and because they are the main ones I actually see locally -- how big do they normally get? I looked them up but can't find as much info, probably because I don't have a scientific name for them.
Actually, now after doing a little research I think the ones I see locally are more likely Crenicichla Sveni and not BellyCrawlers, so I'm not sure if I can even find any locally -- but there is always a chance if I go to some different shops.
Severum make very good tankmates for medium level aggression cichlids like jacks. They are very mellow and usually take the submissive role to more dominant fish. You should defiantly get one that is the same size as your jack, even though they are only semi aggressive if they are the bigger fish in the tank they may chase you jack around.
As far as Jacks being aggressive or peaceful it all depends on demeanor of each individual fish.
