TAXONOMY
Kingdom: Animalia
Phylum: Chordata
Class: Actinopterygii (ray-finned fishes)
Order: Perciformes (Perch-likes)
Suborder: Anabantoidei, (accessory breathing organ known as the labyrinth organ).
Family: Osphronemidae (Gouramies)

Genus/Species: Macropodus opercularis

Paradisefish IMG_7999

GENERAL CHARACTERISTICS: Common length : 5.5 cm (2 inches). Can reach 10 cm (4 inches). Conspicuous dark brown opercular spot with whitish posterior margin (margin red in life); body with 7-11 bold, dark bars on a light background. Caudal fin forked, both lobes elongate with filamentous extension in each lobe

DISTRIBUTION/HABITAT: Native to East Asia from Korea to Northern Viet Nam. Introduced elsewhere. Air breather preferring, slow-moving or still habitats, ranging from irrigation ditches, rice paddies, streams and stagnant ponds to marshes and the backwaters of major rivers.

DIET IN THE WILD: Omnivore consuming planktonic invertebrates and smaller fish. 

REPRODUCTION: The males build bubble nests . After courtship, the male wraps himself around the female in a nuptial embrace during which he fertilizes eggs released by the female. He then gathers up the eggs in his mouth and blows them into the nest. . The male then tends the eggs until they hatch about 36 hours later.

CONSERVATION: IUCN Red List; Least concern.  M. opercularis has a large distribution area and there are no known widespread threats to this species.

REMARKS: Used as predators of mosquito larvae and to control Dengue Fever.

These fish are thought to be one of the first fish introduced to Europe as an ornamental fish, in the mid 1800s.

Males must be kept separate from each other in tanks to prevent fighting,

TAXONOMY

Kingdom: Animalia
Phylum: Chordata
Class: Actinopterygii (ray-finned fishes)
Order: Perciformes (Perch-likes)
Family: Osphronemidae (Gouramies)

Genus/species: Trichogaster trichopterus


GENERAL CHARACTERISTICS: Usually silvery blue in color but their colors can change significantly with their moods, as well as during spawning, when they obtain a much deeper blue hue.The three-spot gourami displays only two spots, one in the center of the body and a second on the caudal peduncle. The eye is actually the third “spot”. T. trichopterus has many different colour forms and varieties, all of which have been selectively bred for the aquarium trade. These are seen much more often than the natural form, which is the blue-grey three spotted fish. They include gold, opaline, cosby, marbled and silver forms. Length to 15 cm (6 inches).

DISTRIBUTION/HABITAT: Southeast Asia: Mekong River basin in Laos, Yunnan, Thailand, Cambodia, and Viet Nam. Preference is thickly vegetated fresh water in ditches, canals, ponds, swamps, rivers or lakes.

DIET IN THE WILD: Omnivore. Eats insects, crustaceans, and zooplankton.

REPRODUCTION and DEVELOPMENT: Typical of gouramis, male builds bubble nest, usually under a large leaf, after which he displays to female. Their courtship ends with her releasing eggs, which the male fertilizes and then collects in his mouth and “spits” into the bubble nest, where he guards them until they hatch in 2–3 days.

CONSERVATION: IUCN Red List; Least Concern (LC) Abundant to common in suitable habitats throughout its range.

REMARKS: Like all labyrinth fish, the moonlight gourami has a special lung-like organ that allows it to breathe air directly from above the water line. This allows gouramis to survive in pools with a low oxygen.

TAXONOMY
Kingdom: Animalia
Phylum: Chordata
Class: Actinoptergii
Order: Pecifomes
Family: Osphronemidae (Gouramis)

Genus/species: Trichogaster microlepis

GENERAL CHARACTERISTICS: It has a greenish hue similar to moonlight glow, hence its name, and a distinctive concave head. Males can be identified by the orange to red color of the pelvic fins and the long, pointed dorsal fins. The female’s pelvic fins are colorless to yellow, while the dorsal fins are shorter and rounder. Length: 12–15 cm  (4.66 – 6 inches)

DISTRIBUTION/HABITAT: Thailand and Cambodia. Found in ponds, lakes and swamps with shallow, sluggish or standing water and abundant vegetation.

DIET IN THE WILD: Omnivorous. Eats insects, crustaceans, and zooplankton.

REPRODUCTION: Oviparous; a bubble nest builder. The bubble nest does not contain much plant matter so the bubbles float around freely. The male performs a courtship dance beneath the nest, culminating with the male wrapping itself around the female and turning her on her back as she releases her eggs. Up to 2000 eggs may be laid during the spawning. The male fertilizes the eggs as they float up to the prepared bubble nest. Eggs incubate in the nest for 2–3 days before hatching.

CONSERVATION: IUCN: Least Concern (LC)  No major threats to this species have been reported, however, pollution in wetlands, infrastructure and draining water may impact the species.

REMARKS: Like all labyrinth fish, T. microlepis has a special lung-like organ that allows it to breathe air directly from above the water line. This allows gouramis to survive in pools with a low oxygen.
