For the jacks, 1. Probably no other fish. You might get buy with somethign to clean up but idk. You also might get buy with a breading pair but if you did there would be next to no chance of anything else being in there. I haven't kept them myself though. Also i hear Electric Blue Jack Dempseys tend to be more peaceful, but they also aren't near as hardy as the normal Jack Dempsey
A breeding pair would be nice, though Id have to clean out the eggs since I dont want to deal with fry. I like regular Jacks more than the blues so I wouldnt bother with the electric blues ^^
Not sure what could live with them though, even as a clean up crew o.o
If you want something different maybe try African clawed frogs!! Or perhaps or turtle! Or I was thinking maybe tanganyikan biotope there always cool. ;) like so e shell dwellers and few calvus! Maybe you can Get a salvini cichlid? Or a pair of sajicas?
I'm just putting ideas out there :)
Ive looked at turtles and stuff like that, but I want a fish tank so something that can live underwater all the time. No frogs since I swore them off after having a pacman frog XD
Ill look into the cichlids ^^
African cichlids look awesome, I hate that they fight though. If you do buy the flat rocks at a hardware store, still expensive but not that expensive. Oh and one thing about cichilds, make sure the ones you get are from the same lake because some have different needs. Peacocks and electric yellows are my favorite.
The lakes always confused me x.x
I'll find something I like though and then base other inhabitants off that so Ill make sure everything is compatible c:
Cichlids are gorgeous fish. We breed them in my first period (Tampa being the fish producing capital of the US), we have a class called Biotech. We basically breed pet store fish like mollies, oscars, cichlids, gouramis, all sorts of tetras, guppies, & I'm working on setting up betta breeding soon if my teacher lets me. :D They work great with cray fish too.
Oh that sounds like a neat class! Wish we had something like that in california :o
Crayfish go along with cichlids? That would be an awesome thing to have in a tank :D
