[Ebook] The New Guide to Aquarium Fish – Characins – Splash Tetras
The splash tetras belong to the same family as the pencilfishes. Unfortunately the majority are rarely deliberately imported for the aquarium trade but do turn up occasionally in shipments of other fishes. The only one seen on a fairly regular basis is Copella arnoldi (Splash tetra, Jumping characin), the fish that gives the group its common name. A fairly unassuming fish to look at, males are larger, growing to 8 cm (3 1/4 in), and have more colour in their finnage than females, 6 cm.
