Whether spots or stripes the red markings are usually at least partially edged with black.Our eastern newts are members of the genus Notophthalmus. Those seen in the pet trade are the four subspecies of the red-spotted newt, N. viridescens. Of these, two subspecies, the red-spotted and the broken-striped newts are, respectively, attractively adorned with a row of black edged vermillion spots or intermittent stripes along both sides of their dorsa. The remaining two subspecies, the pleasantly colored central, and the particularly drab peninsula newts usually lack most, or all, traces of red.

The eastern newts are rather small creatures. The largest race, the red-spotted form, tops out at a mere 5 1/2" in total length. All four subspecies of the eastern newt have quite complex life cycles. Eggs are deposited in water, and hatch into prominently gilled larvae. After a period of time, if conditions are right, the larvae resorb their gills and transform into rough-skinned, often brightly colored, terrestrial dwelling subadults. At this stage of their lives, the creatures are often referred to as "efts." In the northeast, central, and some areas of the south, red or red-orange are the common colors of the efts. Efts in the deep south are often only little, if any, brighter than the adults. This stage exists, conditions allowing, for from one to several years. After completing the eft stage (which is foregone entirely in some newt populations or if terrestrial conditions are unfavorable) eastern newts return to the water, fade in coloration from red to olive-green (with black spotted yellow bellies) and, there, complete their lives.

Adult eastern newts are often sold as "oddities" for aquaria. Slow moving, they are compatible with most "community tank" fish, but will prey upon fish eggs or freshly dead baby livebearers. Adult washed brine shrimp, blood and whiteworms, and chopped earthworms are relished by newts. Some prepared fishfoods are also consumed. Their skin secretions usually protect newts from the occasional aggressive tankmates.
