Tank-Raised Rummynose Tetra (Hemigrammus bleheri)

Same red-nose color-fade indicator and same tightly synchronized shoaling behavior as a wild rummynose, but bred out over captive generations, which means an easier adjustment to tap-adjacent water and less handling stress coming into a new tank. It's a meaningful upgrade for anyone who wants the classic rummynose precision-schooling display without the wild-catch supply chain. Give it a real group and the same block-like synchronized movement shows up.

Care level: Easy · Temperament: Peaceful, shoaling · Max size: ~2" · Min tank: 20 gal · Diet: Omnivore, flake/micro-pellet
