About the Cover

Known collectively as Cuban topminnows, the diminutive livebearing fishes of the genus Girardinus are found in the streams, small rivers, and ditches of their native Cuba. This issue’s cover features a metallic topminnow (G. metallicus), a color form known as the blackchin or blackbelly topminnow, which, as Mike Hellweg explains this month, is thought to have been derived from a population from a river in Cuba where the males of the species are almost entirely black.

Tip of the Month:

Plug your filter and heater into a power strip separate from your lights. Then, when you go to drain the tank to change water, you can shut off the filter and heater, preventing damage due to low water, but still have the lights to see to properly vacuum the gravel.
