Chinese Perch “Red Stripes” (Siniperca chuatsi) 8-15 cm

A robust, elongated freshwater fish known for its shimmery brownish-yellow body adorned with dark blotches and pronounced stripes running through the eye and along the lateral line. Some selective captive-bred variants show intensified red or orange fin accents—hence “red stripes.” Its large mouth and rows of sharp teeth mark it as an effective ambush predator.

Tank Setup:

• Very large tank required—think 400 L+ for even small specimens to ensure comfort and natural behavior.

• Include dense planting, heavy driftwood, and rock structures for hiding.

• Ensure excellent filtration and aeration; strong water movement isn't necessary, but oxygen-rich conditions are critical.

• Secure, sturdy lid to prevent escape.

Water Conditions:

• Temperature: can stay inactive near 1–5 °C but feeding starts above 15 °C; breeding occurs above ~21 °C—optimum growth between 20–24 °C.  pH: neutral to slightly acidic or alkaline (approx. 6.5–7.5)

• Water clarity and quality are paramount—prefer clean, well-oxygenated, and structured water columns.

Diet:

• Strict carnivore: feeds on moving live prey—small fish, shrimp, and other live aquatic animals. Bass-shape or fry are typical targets.

• Does not accept static or dead food unless conditioned; live feeding is standard in both farming and aquarium settings.

• Behavioral note: in high-density farm settings, they can become cannibalistic if not well-fed.  

Behavior & Tankmates:

• Demersal ambush predator—quiet, lurking, with sudden bursts to catch prey.

• Aggressive and territorial; best kept alone or with much larger, robust tankmates in very large systems. Not suitable for community tanks.

Breeding & Lifecycle:

• Breeding begins once water exceeds approx. 21 °C—the wild fish spawn in flowing water at night during warmer months.

• Females mature at ~2 years (≥21 cm), males at ~1 year. They produce tens of thousands of eggs, which are semi-pelagic in current.
