Before you choose from this collection
This page collects the fish and invertebrates that genuinely help control algae — grazers that earn their place in a maintenance routine. Everything listed is live stock held in our own system, dispatched with a licensed live-animal courier under our live arrival guarantee.
Real algae grazers include bristlenose plecos, otocinclus, Siamese algae eaters, nerite snails and Amano shrimp. Each targets slightly different algae, and none is a magic fix — they supplement good tank management rather than replace it.
Read the notes linked below before ordering. The classic mistake is buying a 'common pleco' or Chinese algae eater that grows large or stops eating algae as an adult; the species on this page are chosen because they stay useful and appropriately sized.

Frequently asked questions
It depends on the algae and tank size. Bristlenose plecos are the best all-round algae-eating fish for most tanks; otocinclus are superb on soft green algae in mature planted tanks; nerite snails clean glass and hard surfaces without breeding; Amano shrimp tackle hair algae. Often a small mixed clean-up crew beats any single species.
No — and any that claims to is overselling. Algae eaters reduce and manage algae, but they can't fix the underlying causes: excess light, excess nutrients and infrequent maintenance. Treat them as helpers alongside sensible lighting periods, water changes and not overfeeding, not as a substitute for them.
The common pleco (grows to 40-60 cm and produces huge waste) and the Chinese algae eater (becomes aggressive and stops eating algae as it matures). Both are sold small and cause problems later. Stick to bristlenose plecos, otocinclus, nerites and Amano shrimp, which stay useful and suitably sized.
Nerite snails and otocinclus start at about £2-£4, bristlenose plecos and Amano shrimp £4-£8, and fancy pleco strains more. A small mixed clean-up crew of a few species usually works better than one of any single grazer. Prices on this page are live: what you see is what's in stock today.
Usually yes. A well-maintained tank doesn't grow enough algae to sustain a grazer full-time, so supplement with algae wafers, blanched vegetables (courgette, cucumber) and, for plecos, driftwood to rasp on. A starving algae eater is a common and avoidable problem — feed them properly even in a clean tank.
Yes. Fish and invertebrates alike ship in oxygen-charged bags inside a polystyrene-insulated box with a heat pack in winter, handed to a licensed live-animal courier, dispatched Wednesday for Thursday delivery so they never sit over a weekend. Every delivery is covered by our photo-proof live arrival guarantee.
