Name: Hyalinobatrachium fleischmanni , Fleischmann’s Glass frog or Northern Glass frog

Recommended Vivarium Size: Fleischmann’s Glass frogs are very arboreal so a male and female pair should like a 20 gallon or an 18x18x24 front opening tank. These frogs will need a lot of vegetation in their tanks to feel comfortable as they are fairly shy during the day. A water dish of clean water should be provided for these frogs at all times. Either biobedding or ABG topped with sphagnum should be provided for substrate.

Temperature: 72-78

Humidity: 50-70

Size: Males are just under 1” and females are slightly larger than 1”

Age: Fleischmann’s Glass frogs can live for about 5-8 years, but may live longer with ideal care.

Feeding: As adults Fleischmann’s Glass frogs can eat ¼” crickets and other similar sized feeder insects.

Sexing: Male Fleischmann’s Glass frogs will be slightly smaller than females and emit advertisement calls. A male’s call is a light peep but can also emit a “mew” when it’s territory is invaded by another male.

Color/Pattern: Fleischmann’s Glass frog is light green with light yellow spotting. Its underbelly is partially transparent with its internal organs covered by a white guanine sheet.

Social Behavior: Male Fleischmann’s Glass frogs are very territorial and will fight and potentially kill other males. It is advised that keepers keep only a male female pair or a group that is female heavy.

Breeding: Fleischmann’s Glass frogs will breed on leaves overhanging streams. They will lay clutches of 15-30 eggs at a time. Parents are fairly protective of their eggs and will sit on the clutch during the nighttime and males will release bladder water onto the clutch to prevent dessication.

Development: Eggs take approximately 5-12 days to hatch and tadpoles will fall into the water below.

Tadpoles: Tadpoles may need moving water to thrive as they are typically found in streams. The will readily eat a variety of fish foods including Josh’s Frogs Tree Frog tadpole food.

Natural Range: This species occurs from Guerrero and Veracruz in southern Mexico, south through Central America to Colombia (in the Pacific lowlands south to Valle del Cauca, in the Middle Magdalena Valley, and on the western slopes of the Cordillera Oriental). (IUCN red list)
