🐟 Rainbow Shark (Epalzeorhynchos frenatum)
A Velvety Dark Body With Blazing Red Fins • A Sleek Mini-Shark Shape • A Bold, Active Thai Native
📋 The Rainbow Shark, also known as the Ruby Shark or Red-Finned Shark, carries a sleek, velvety blue-black body set off by blazing red-orange fins, giving it a dramatic contrast that stands out in any tank. Its torpedo-shaped body and tall dorsal fin give it the look of a miniature shark.
It comes from Southeast Asia, from the Mekong and Chao Phraya river basins of Thailand, Laos and Cambodia. Every Rainbow Shark we ship is feeding well.
This is a bold, active fish that patrols the lower levels of the tank, grazing algae from rocks and driftwood and adding constant movement. It's a confident character that claims its own patch of the tank, so it's best kept as a single shark with lively mid-to-upper level tankmates. It's plant-safe and grows up to 15cm, so a 200L tank suits it well.
