The native range of the Glowlight Tetra is the Essequibo River in Guyana where it inhabits the tannin-stained acidic waters that flow through thick jungle cover. This species is one of the best choices for the general community aquarium. Most aquarium livestock available is captive bred on a mass scale. Captive bred species are usually more hardy and adaptable than wild caught which, therefore, makes this an excellent choice for the newcomer to the aquarium hobby. Since the Glowlight Tetra is a shoaling species, purchase no less than a group of six. Ten or more will light up an aquarium with a magnificent show!
