OK, here's the (long) story: > (SNIP) > > Now, I took Axelrod's Mini Atlas out of the library, and looked up Rummy-nose > tetra (Hemigrammus rhodostomus). The picture there was not similar to the > actual fish I saw or to the other book's picture.
One of our friends, Margarita (you will hear more about her and her tank in a future update) had acquired a school of Hemigrammus rhodostomus which were a really nice addition to her planted tank.
Even though a kribensis (Pelvicachromis pulcher) is larger than a rummy-nose tetra (Hemigrammus rhodostomus), the rummy-nose tetra compensates with its constant activity, which requires quite a bit of oxygen to fuel its metabolism.
Recognizing that this fish was physiologically distinct from Hemigrammus rhodostomus, Gery & Boutiere erected the genus Petitella [from the French petit meaning small, diminutive] for this species, which is still the sole species in the genus.
They are particularly striking against a background of light green plants.
Two similar species are often sold under the same common names - Hemigrammus rhodostomus and Petitella georgiae (False Rummy-Nose tetra).
