Overview
What to know before you buy.
One of the few fish that reliably grazes black beard algae. Best kept in groups of four or more in a planted tank with steady flow; adults are fast, need swimming length, and are often confused with the less useful flying fox.
Care guide
Keeping Siamese Algae Eater healthy in a South African setup.
Tank setup
A minimum 120L aquarium suits Siamese Algae Eater. Provide hiding spots and stable, well-filtered water; it suits a community setup.
Water parameters
Keep pH 6–8 and 24–26°C. Stable parameters matter more than chasing perfect numbers; acclimate new arrivals slowly.
Feeding
Omnivore — algae, biofilm, prepared foods. Feed small amounts it clears in a couple of minutes, and vary the diet.
Behaviour
Peaceful, active shoaler. 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 Siamese Algae Eater 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.
