Species Profiles
Rummy Nose Tetra
Hemigrammus rhodostomus
Rummy nose tetras are considered the ultimate schooling fish in the freshwater hobby. Their tight, synchronized formations are unmatched by any other tetra species. The vivid red nose serves as a health indicator — bright red means healthy, pale red means stressed. They prefer soft, acidic water and are slightly more demanding than neon tetras.

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.
