{"product_id":"koi-angelfish-medium","title":"Koi Angelfish (Pterophyllum scalare)","description":"\u003cp\u003eKoi Angelfish take their name from an obvious comparison: the orange, black, and white patterning that makes koi distinctive in a pond shows up here in the flattened, sail-finned body of \u003cem\u003ePterophyllum scalare\u003c\/em\u003e. The pattern comes from marbling genetics, which means the coloring is more variable than a solid strain — the ratio of orange to white to black shifts as the fish grows and the marbling gene continues doing its thing. A juvenile that's mostly white and orange may develop significant black by adult size, and vice versa.\u003c\/p\u003e\u003cp\u003eIn a planted tank with a light substrate, koi angels bring a visual warmth that darker and standard silver strains don't — they read as colorful without competing with the flora the way a neon or rainbow species might. A small group of three to five in a 55+ gallon planted setup tends to establish loose schooling behavior in their first few months before pairing off, which gives you a window into both their schooling and their cichlid sides.\u003c\/p\u003e\u003cp\u003eLike all angelfish, a bonded pair will claim territory and defend it seriously. Other angelfish in too small a space will be driven away — adequate tank size and visual structure (tall plants, driftwood) lets multiple pairs coexist without constant conflict.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eScientific name:\u003c\/strong\u003e Pterophyllum scalare (koi\/orange marble strain)\u003cbr\u003e\u003cstrong\u003eOrigin:\u003c\/strong\u003e Amazon River basin, South America\u003cbr\u003e\u003cstrong\u003eWater parameters:\u003c\/strong\u003e Temp 76–86°F · pH 6.0–7.5 · Soft to moderately hard water\u003cbr\u003e\u003cstrong\u003eTank requirements:\u003c\/strong\u003e 30 gal minimum; tall tank preferred\u003cbr\u003e\u003cstrong\u003eDiet:\u003c\/strong\u003e Omnivore — flake, pellet, frozen bloodworms and brine shrimp\u003cbr\u003e\u003cstrong\u003eCompatibility:\u003c\/strong\u003e Peaceful community when young; semi-territorial once paired\u003cbr\u003e\u003cstrong\u003eHusbandry note:\u003c\/strong\u003e The koi pattern tends to shift and intensify over the first year as the fish matures.
