Fresh Water Fish Breeds.
This catfish is usually bluish-black or reddish- brown, with some speckling. Thorocatum Catfish are easy to sex when in breeding condition, since the rays of the male’s pectoral fins turn orange, while the underparts suffuse with a bluish-violet coloration. Spawning is very vigorous, with the male often pursuing the female aggressively. The eggs are deposited in a bubble-nest at the surface among vegetation, and will be guarded until they hatch.
This fish often has a threadlike extension at the back of the dorsal fin. The front of the body is white, but the rear part is yellow, including the caudal fin. There are false eye-spots on the dorsal fin, while the real eyes are hidden by a black band. Butterflyfish have not yet been bred successfully in aquariums. In the wild, they spawn toward dusk near the surface, and their young feed on plankton.
Mature males display with their elaborate fins during the courtship ritual, holding them erect and then flicking them up and down. An aquarium planted with fine-leaved vegetation is essential for spawning; females lay over the course of several days. The eggs can take a week or longer to hatch, and the fry can be reared on tiny rotifers. Adult fish prefer to eat small livefoods, but will take flake powdered onto the water’s surface.
Contrary to their name, the spotted patterning of Three-Spot Gouramis is variable, as is their coloration. These fish can be sexed by the dorsal fin, which has a more elongated tip in males. Three-Spots are easy to keep, because they are hardy and unfussy eaters. The male creates a bubble-nest up to 10 in (25 cm) across at the surface among floating plants. After spawning, remove the female to protect her from the
male. The fry should initially
A variable but vibrant body patterning, including a large black mark on the dorsal fin, characterizes these corydoras. Females are generally slightly paler in color than males, with a smaller patch on the dorsal fin. The “three stripes” in the common name of this species refer to the central stripe running along the side of the body, and the lighter lines above and below.
These sticklebacks show a distinct difference in coloration between the sexes during the spawning period, when male fish become red and blue. The male builds a nest out of plant matter and lures a succession of females inside so that they can lay their eggs, which he fertilizes. In total, the nest may contain as many as 50 eggs from different females. The male guards the eggs, and also watches over the newly hatched fry.
The males are more colorful and possess black markings on the dorsal fin,which are missing in the females.Keep this fish in cool water for a time and then gradually raise the temperature to trigger spawning.Placing two males with a single female is favourable.
The banding of these barbs vary between individuals.The red areas on the body are brighter in males than in females.They are best kept in large groups with adequate open swimming area as they are active by nature.
A delicate patterning of white stripes on a black background distinguishes the Tiger Clown Pleco. These markings are highly variable, allowing individuals to be recognized easily. Females lack the spines on the pectoral and dorsal fins, and have a broader body shape. Tiger Clown Plecos are most active after dark, and eat a wide variety of foods. Shelled peas, either fresh or thawed, are a valuable source of vegetable matter, as are cucumber slice
The spotted patterning that characterizes young Scats alters as they mature with the background color becoming silvery rather than golden. Being vegetarian, these fish will damage or destroy living plants in their aquarium. Java Fern (Microsorum pteropus) must not be incorporated, since it may be toxic to Scats if they eat it. Scats are active fish by nature, and a group will require a large, spacious aquarium.
