L397 – Alenquer Tiger Pleco (Panaqolus sp. “L397”) 

---

Species Overview

• Scientific Name: Panaqolus sp. L397 (commonly known as Alenquer Tiger Pleco, Red‑striped Alenquer Pleco) 
• Origin: Native to the Lower Amazon near Alenquer, Brazil 
• Size: Typically grows to about 4–5 inches (10–12 cm) SL 

---

Appearance & Sexual Dimorphism

• Bold orange to red stripes alternating with black, sometimes separated by transparent bands 
• Juveniles may display more distinct fin striping; adults retain fin vibrancy even if body color fades slightly 
• Males develop odontodes (bristle-like projections) on the caudal peduncle and along pectorals; females appear broader when gravid

Water Parameters & Habitat

• Temperature: 75–86 °F (24–30 °C), ideally 78–82 °F
• pH: Optimal range 6.4–7.5 (tolerates 5.5–7.7)
• Hardness: KH 2–10°, some sources note tolerance up to KH 20° 
• Prefers well-oxygenated, moderate current environments typical of its native driftwood‑filled streams 

---

Diet & Feeding

• A natural wood‑eater (xylophage): requires driftwood in the tank to rasp for fiber and biofilm 
• Supplement with:
  • Algae wafers, sinking pellets (vegetable-based) 
  • Blanched vegetables (zucchini, cucumber, sweet potato, yams, Brussels sprouts) 
  • Occasional meaty treats (blackworms, clams, shrimp) 1–3 times weekly 

---

Tank Setup & Compatibility

• Minimum tank size: 30 gallons is recommended for a single adult, with adequate space for driftwood and caves 
• Substrate: Fine sand or smooth gravel
• Decor: Multiple pieces of driftwood, caves, rockwork; floating plants optional but helpful for shaded retreats 
• Filtration: Strong filtration with moderate current and high oxygenation 
• Behavior: Generally peaceful; may show territory over caves with conspecifics 
• Tankmates: Compatible with tetras, corydoras, community cichlids; avoid delicate shrimps and plants that may be rasped

Breeding & Lifespan

• Spawning:
  • Breeds in caves, often bamboo or ceramic; males guard eggs (~25–40 per spawn) 
  • Water specs during breeding: 24–30 °C, conductivity 200–700 µS/cm 
  • Fry dependent on wood and high-protein/vegetable diet; reach sexual maturity ~1 year 
• Lifespan: Typically 8–10 years in well-maintained conditions

Common Challenges & Care Tips

• Not efficient algae eaters—primarily wood grazers; algae growth should be managed separately 
• Requires plenty of driftwood to prevent malnutrition and maintain digestive health 
• High water quality and regular maintenance are key, as wood breakdown can elevate waste levels 
• Prone to territorial disputes only in inadequate cave setups—provide multiple hiding spots for multiple plecos
