That helped a lot

i got rid of a lot of stress! however i dont really want tetras. i want a cichlid that doesnt grow big, isnt small enough to be bossed around by the pike, pretty and that is fairly easy to spawn. The fish i most want is probably some kind of small geophagus i love them. i will try to find a home for the fishes. Is the oscar ok to let go or is it domesticated??? i know that you cant let most fish go but oscars are native to brazil. thanks a lot a teleocichla would be neat but finding it in a store would be 1 chance in a hundred. looking for more options thanks.
