Myxocyprinus asiaticus - Tropical Fish for Sale UK

Overview

The chinese high fin banded shark (Myxocyprinus asiaticus) is a striking, peaceful cold-water giant from the Yangtze River basin in China. Available for sale UK through Tropical Fish Co, this unique sucker fish starts tiny but grows into a massive, long-lived show fish reaching over 1 metre in length. Only suitable for very large aquariums or ponds, this species rewards experienced keepers with decades of companionship and an unmistakable aquatic presence.

Appearance

Myxocyprinus asiaticus reaches up to 130 cm in length and displays a distinctive high dorsal fin and bold banding pattern in juveniles. Young specimens (4–5 cm) are pale with dark vertical bands and a dramatic sail-like dorsal fin. As the fish matures, banding fades and the body becomes more uniform grey-brown. The ventral sucker mouth is adapted for grazing algae and biofilm from surfaces.

Natural Habitat

This species is native to the Yangtze River basin in China, where it inhabits large, fast-flowing rivers with rocky substrates, cool water, and high oxygen saturation. In the wild, M. asiaticus feeds on algae, biofilm, detritus, and organic matter, migrating seasonally and living for many decades. These environments are characterized by cool temperatures, strong current, and abundant grazing surfaces.

Aquarium Setup

This species grows extremely large and is only suitable for very large, well-filtered, cool-water aquariums (3,000+ litres) or ponds. Juveniles are often sold small but outgrow standard aquariums quickly. Provide strong filtration, high oxygenation, smooth rocks, and ample swimming space. Cool-water conditions are essential—tropical temperatures will stress and shorten the fish's lifespan.

Water Parameters

Maintain cool, clean, well-oxygenated water between 10–24°C with a pH of 6.5–8.0. Excellent filtration and frequent large partial water changes (50% or more weekly) are essential to keep water pristine. This species is sensitive to poor water quality and warm temperatures, requiring consistent maintenance. Monitor parameters closely and prioritize oxygen saturation.

Feeding

Myxocyprinus asiaticus is primarily herbivorous with omnivorous tendencies. Offer a varied diet of algae wafers, sinking herbivore pellets, blanched vegetables (spinach, courgette, peas), plus occasional frozen or live foods (bloodworms, brine shrimp). Feed generously to support growth, and remove uneaten food promptly to maintain water quality.

Behaviour

This species is peaceful, calm, and entirely harmless, spending its time grazing algae and biofilm from surfaces or swimming gracefully through open water. Juveniles are active and curious; adults become more sedate but remain gentle and non-aggressive. They are solitary and do not form social bonds, though multiple individuals can coexist if space permits.

Tank Mates

Ideal companions include large, peaceful cool-water fish of similar size, other non-aggressive species that can tolerate strong current and ample space, and robust fish that will not be outcompeted at feeding time. Avoid small fish that may be outcompeted or eaten, aggressive or fin-nipping species, warm-water tropical fish, and very small invertebrates. This species does best in spacious, calm setups.

Breeding

Breeding is uncommon in home aquaria and typically requires very large systems, seasonal temperature changes, and strong current. Little reliable captive-breeding information is available. This species is not suited to breeding by hobbyists, and most specimens are wild-caught or bred in commercial facilities.
