Albino Rainbow Shark
Epalzeorhynchos frenatum
Animalia›Chordata›Actinopterygii
Variety of Rainbow Shark · albino
📍 Southeast Asia
The Albino Rainbow Shark has a pale white or pinkish body with the characteristic red-orange fins of the species. It is equally territorial as the standard form and should be kept one per tank in a well-decorated aquarium with plenty of hiding spots.
Care Guide
Diet
Albino Rainbow Sharks are omnivorous and should be fed high-quality sinking pellets as a staple, supplemented with frozen foods like bloodworms and brine shrimp 2-3 times weekly. They will also consume algae wafers and vegetable matter such as blanched zucchini. Feed once daily in amounts they can consume within 2-3 minutes.
Behavior
Highly territorial and aggressive, especially toward other bottom-dwellers and similar-looking fish, requiring one shark per tank. They are nocturnal and most active during dawn, dusk, and nighttime hours, spending much of the day hiding in caves or dense vegetation. They are generally solitary and do not tolerate conspecifics or other sharks.
Breeding
Breeding in captivity is extremely rare and difficult, with very few documented successful spawns in the aquarium hobby. They require very large tanks (200+ gallons), specific water conditions, and compatible pairs are difficult to establish due to their aggressive nature. Most specimens in the hobby are wild-caught or tank-bred in commercial facilities under specialized conditions.
Tank Mates
Small, peaceful algae eaters that occupy different tank zones and are unlikely to trigger territorial aggression
Fast-moving mid-water schoolers that avoid bottom areas where the shark hunts, reducing conflict
Nocturnal bottom-dweller; may compete for space and food, requires careful monitoring and ample hiding spots
Peaceful schooling fish that stay in mid-water columns and are too quick to be easily targeted
Slow-moving invertebrate that occupies different ecological niche and is generally ignored by the shark
Common Diseases
Ich (Ichthyophthirius multifiliis)
White spots on body and fins, rapid breathing, flashing against decorations, lethargy
Raise water temperature to 28-30°C, perform daily 25% water changes, use ich medication (malachite green or formalin-based treatments) following label directions for 7-10 days
Fin Rot
Frayed or deteriorating fins, discoloration at fin edges, fin shortening
Improve water quality with frequent partial water changes, maintain optimal temperature, use antibacterial medication if severe, remove sharp decorations that may cause injury
Bacterial Infection
Open sores, ulcers on body, cloudy eyes, loss of appetite, color fading
Perform 50% water change immediately, treat with broad-spectrum antibiotic medication, maintain pristine water conditions, isolate if possible to prevent spread
Parasitic Infection
Excessive scratching, visible parasites, weight loss, clamped fins, lethargy
Use anti-parasitic medication appropriate for freshwater fish, perform daily water changes during treatment, quarantine affected fish, treat for 7-14 days depending on medication
