I would have thought there would be plenty of pages on these guys. Anyhow i don't know how big that tank is but i wouldn't keep them in anything smaller than 3' long, they grow large for a tetra and are very active swimmers, plus like other tetras need to be kept in a school. Also wouldn't keep them with much smaller timid tetras such as neons which might get bullied or nipped. Otherwise they are quite hardy and beautiful when mature.
