alrighty i will tell you my personal experience with these fish.
yes, cories, cons and JB parrots can go together. th tank size has a big part of this though. the personality of each fish goes into play as well. i have 3 reticulated cories (grow about 3" or so), a pair of breeding JBs (thought they both were female until i found eggs one day), and a pair of brreding convicts (only 1" big at this time) and they all do fine together. the cories are never attacked and the pairs never fight.
part of this i feel is that when all my fish are young (about an inch or less) i purposely put them in a tank with a larger fish to kinda scare them a bit. dont think its cruel people its a sailfin pleco lol not a bigger threat. but the fish naturally are scared of the bigger fish, and the pleco is peaceful so no damage ot the fish. so in the tank they are in i keep this pleco and all is well. they stay peaceful a bit more. but just because this works for me doesnt mean it'll work for everyone.
persoanlly i wouldnt go with angels for a couple of reasons. first off i dont like them lol. second i dont know much about them, but i think they would get harassed to death by convicts and JBs. the only thing that would be bad is if you're angels paired off, they would get incredibly aggressive.
i also have a bunch of snails in the tank ranging from all types and sizes. from apple, to ramshorn to malaysian trumpet snails. only one of the fish eat the snails on me. this is my smallest JB. she was doing the typical moving of the gravel one day when she pulled the shell of a malaysian trumpet snail (MTS) she turned it around thinking it was a rock and sucked the snail up (right out of the shell). well she developed a taste for them and eats them on me. the mts are the only ones she touches though.
as for breeding. JBs and cons an interbreed. cons can virtually breed with anyhting there is out there lol. but whether you fell JBs are jsut shortbodied cons or BP x con they still are at least part convict so they will be able to breed.
hmm... did i miss anything?
oh yea, the shrimp, unless you want ot treat the cichlids to a snack i wouldnt get them. about 6 months ago i kept buying ghost shrimp for my tank and found out that between the JB and the male betta in my tank, the shrimp were becoming meals once the malted and became vulnerable.
well that is my experience, if you want any further details, please feel free to PM me and i will tell you more
