i currently have a paraya, yellow-tail barracuda, needle nose gar, ornate bichir, common pleco, and a stiped rafael cat all within 7-10 inches housed in a 75 gallon. i want them to have enough room to be healthy so i'v decided to upgrade to a 180 gallon. im thinking about getting one last fish and i was really interested in the peacock bass simply because its beautiful and it comes from the Amazon basin like most of my other fish. i want some opinions on if i should do this or maybe get a partner for one of my other fish like the gar or paraya. if you have a suggestion on another type of fish from the amazon please feel free.
