Whiptail Catfish

Quick Answer

Whiptail Catfish (Rineloricaria spp.) is a unique, elongated catfish from South America. It requires a minimum 30 Gallons aquarium with a pH of 6.5 - 7.5 and temperature range of 22-26°C. This omnivore occupies the bottom zone and makes an excellent addition to community setups.

Intro

Whiptail Catfish (Rineloricaria spp.) is a unique, elongated catfish from South America. Its long, thin body and filamentous tail give it a distinctive appearance.

Setup

A 30-gallon or larger tank with smooth sand substrate, driftwood, and caves. Moderate water flow. They are sensitive to poor water quality, so regular changes are a must.

Feeding

Omnivorous; eats algae, biofilm, sinking pellets, algae wafers, frozen bloodworms, and blanched vegetables.

Compatibility

Peaceful and shy. Keep in groups of 3+. Ideal for community tanks with small tetras, rasboras, Corydoras, and dwarf cichlids.

Frequently Asked Questions

How many Whiptail Catfish should be kept together?
Maintain a group of 3 to 5 individuals in a tank of at least 30 gallons (113 liters) with a footprint of 36x12 inches (90x30 cm). Whiptail catfish (Rineloricaria spp.) have long, slender bodies and are exceptionally peaceful, gentle bottom dwellers that do well with nano fish. Groups under 3 cause stress. Provide smooth sand or fine gravel substrate to prevent damage to their bodies. Add driftwood and flat rocks. Avoid aggressive cichlids and large plecos.
What are the exact water parameters for Whiptail Catfish?
Target pH 6.5 - 7.5, General Hardness 3 - 10 dGH, Carbonate Hardness 2 - 8 dKH, Total Dissolved Solids 80 - 200 ppm, Electrical Conductivity 160 - 400 μS/cm, and temperature 72°F - 78°F (22°C - 26°C). They require clean, well-oxygenated water with low nitrates (<10 ppm). Maintain weekly 25% water changes. Use a sponge or canister filter with gentle flow. Sand substrate (1-2 inches depth) is mandatory; gravel damages their snout and barbels. Add driftwood.
What is the dietary and medication protocol for Whiptail Catfish?
They are omnivorous scavengers requiring 40% protein, 10% fat, 50% plant matter. Feed sinking wafers, catfish pellets, spirulina tabs, frozen daphnia, and bloodworms daily. Offer blanched zucchini and cucumber. They graze on driftwood biofilm. Medication alert: Extremely sensitive to copper (0.05 mg/L lethal) and formalin. Scaleless; use malachite green at quarter dose (0.025 mg/L). Praziquantel is safe. Avoid salt (tolerance <2 ppt). Quarantine with metronidazole at half-strength.
How to breed Whiptail Catfish in captivity?
Condition a group of 4-6 with live blackworms and bloodworms for 3 weeks. Simulate rainy season: Perform 40% water change with cool (68°F/20°C) soft water over 2 hours, increase aeration. Provide a spawning cave or PVC pipe (1.5-inch diameter). Male selects cave; female lays 50-150 large adhesive eggs inside. Male guards eggs for 7-10 days at 75°F (24°C). Eggs hatch; fry are 0.3 inches (8 mm) and accept baby brine shrimp and crushed algae wafers immediately. Remove male after hatch. Grow-out requires sand substrate.
