Spotted Copella

Geographic Origin and Biotope: Upper Amazon basin and Guyana. Found in zero-flow, heavily shaded forest streams ('Igarapés'), hovering among floating vegetation and submerged leaves waiting for insect fall.

Taxonomy and Morphology: Copella genus (close relative to the Splashing Tetra). Very elongated, torpedo-like body (4-5 cm) with a sharp, severely upturned terminal mouth purely adapted for surface-dwelling life.

Social Behavior: Peaceful, loose schooler. Very stationary. Spends hours perfectly motionless millimeters below the water surface (often frightening beginners who think the fish is dead or dying). When feeding, it executes blindingly fast, ballistic jumps out of the water to catch flying insects.

Coloration and Sexual Dimorphism: Pale gold/beige base. A distinct black horizontal stripe runs through the eye to the tail, bordered above by a pale red/pink line. Males are slightly larger, significantly slimmer, feature brighter red colors, and possess much longer, trailing dorsal and anal fins compared to the females.

Tank Setup: Minimum 60-80 cm long tank. TIGHT-FITTING LID IS MANDATORY. They will find even a 1 cm gap and jump out. The surface flow must be incredibly slow to stagnant. Dense floating plants (Frogbit, Red Root Floater) are essential to provide shade and hunting cover. Bright lights over an open surface will deeply stress them.

Feeding: Strict surface insectivore. Completely ignores food that sinks. Will accept slow-sinking flakes, but MUST have live/frozen surface insects to thrive: flightless fruit flies (Drosophila), springtails, or freeze-dried bloodworms fed with a feeding ring.

Water Quality: Classic Amazonian parameters: soft, acidic water (pH 5.5-7.0, low GH). Temp 23-27°C (73-81°F). Highly intolerant of ammonia or poor water hygiene.

Compatibility: Perfect dither/surface fish for Dwarf Cichlids or peaceful bottom-dwellers (Corydoras, Plecos). DO NOT keep with frantic surface feeders (Zebra Danios, active tetras) who will outcompete them for food and shatter their peaceful surface existence. Keep in groups of 6-8+.

Reproduction: Unlike the Splashing Tetra (which jumps to lay eggs on aerial leaves), the Spotted Copella lays eggs SUBMERGED, but very close to the surface on the underside of broad floating leaves. The male actively guards and fans the leaf until the fry hatch.

Risks: 1. Death by jumping out of the tank (guaranteed without a tight lid). 2. Starvation in busy community tanks. 3. Thermal/light stress if trapped just beneath hot LED lights.
