Alright,
1) What would be some nice common species for a substitute? Do they have to be Central Americans?
jack Dempsey female, convict, I guess would be some common species. Not too many CA species that are common and aren't centerpiece fish.
2) Could i do a rope/reed fish?
I don't have experience with these fish. I know bichirs work well, so probably?
3) Could i do Boesemani Rainbowfish as dithers?
don't see why not
4)Would a Jaguar cichlid work or no?
No, a jaguar would be a bad choice. too large and aggressive, likely kill stuff.
5) Would a Jardini Arowanna work?
same deal as jag
6) Would the fire eel be fine?
I don't have experience with them but have seen people keep them with large cichlids
7) Could i do some type of larger pleco?
Yes but keep bioload in mind, plecos are poop machines especially big ones. And your tank will already be full of lots of fish. I'd say cut back a bichir or on dithers if you want to add pleco
Sorry for all the questions
No worries good on you for asking
