Overview
What to know before you buy.
A tiny, sociable loach that spends its time bustling in mid-water rather than hiding. Males flush a warm rose when settled in a group of eight or more.
Care guide
Keeping Rosy Loach healthy in a South African setup.
Tank setup
A minimum 45L aquarium suits Rosy Loach. Provide hiding spots and stable, well-filtered water; it suits a community setup.
Water parameters
Keep pH 6.5–7.5 and 22–26°C. Stable parameters matter more than chasing perfect numbers; acclimate new arrivals slowly.
Feeding
Omnivore — micro foods, frozen. Feed small amounts it clears in a couple of minutes, and vary the diet.
Behaviour
Peaceful, sociable nano loach. Watch it at feeding time and at lights-out to see its real temperament in your tank.
Tankmates
Choose tankmates of similar size and temperament with the same water needs. Avoid fin-nippers and anything large enough to eat it.
Breeding
Breeding success with Rosy Loach depends on the line and water chemistry; ask your shop about proven pairs.
Settling this fish in?
Condition the tap water, seed the filter, test through the first weeks — most early losses trace back to one of those.
