Jack Dempsey Cichlid
Rocio octofasciata
Named after the legendary boxer, Jack Dempsey cichlids are large, territorial Central American cichlids with iridescent blue-green spangles across their dark body.

The electric blue Jack Dempsey variant is significantly less aggressive and more colorful.

Metynnis hypsauchen
Silver dollars are large, disc-shaped, peaceful schooling fish related to piranhas — but entirely herbivorous. Their shimmering silver body catches light beautifully in motion. They are excellent dither fish for large cichlid tanks because their calm, open-water swimming behavior helps reduce cichlid aggression. Warning: they will eat every live plant in your tank.
