Do algae eaters completely remove algae?

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.

Which algae eaters should I avoid?

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.

How much do algae eaters cost in the UK?

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.

Do algae eaters need extra food?

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.

Is it safe to buy algae eaters online?

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.
