Before you choose from this collection

Every catfish and pleco on this page is a live fish held in our own system before dispatch — not a stock photo. We stock corydoras, bristlenose and fancy L-number plecos, synodontis, and other catfish, with new imports landing most weeks.

Catfish ship in oxygen-charged bags inside an insulated box, dispatched Wednesday for Thursday delivery with a licensed live-animal courier so your fish never sits over a weekend. Every order carries our live arrival guarantee: email clear photos and your order number the same day; an unboxing video is optional. Approved claims are refunded or replaced under the guarantee.

Catfish and plecos are the workers of the aquarium — bottom-dwellers that forage, graze algae and add real character. Sizes range from 3 cm dwarf corys to plecos that need a very large tank, so read the individual care guides linked below and match the adult size to your setup before ordering.

Frequently asked questions

Partly. Bristlenose plecos and otocinclus genuinely graze algae, and corydoras hoover up leftover food from the substrate — but none of them are a substitute for water changes and filtration. They also need their own food; a 'clean-up crew' still has to be fed sinking wafers, algae tabs or vegetables.
Common corydoras and bristlenose plecos start at about £2-£6, mid-range fancy plecos and synodontis run £15-£40, and rare L-number plecos reach well into the hundreds for sought-after imports. Prices on this page are live: what you see is what's in stock today.
It depends entirely on the species. Bristlenose plecos stay around 15 cm and suit most tanks, but a common pleco can reach 40-60 cm and needs a very large aquarium. Always check the species before buying that cute 5 cm juvenile — this is the single most common pleco mistake.
Corydoras are the classic community catfish — peaceful, small, shoaling and active by day. Bristlenose plecos are the best pleco for a normal-sized tank. Otocinclus are superb algae grazers for planted tanks but need a mature setup. Avoid large or predatory catfish in a community of small fish.
Many do. Bristlenose and several other plecos rasp on wood to aid digestion and graze the biofilm it grows, and keepers often find them healthier with bogwood present. It is not universal — check the species — but for the common home-aquarium plecos, a piece of driftwood is strongly recommended.
Yes. Catfish and plecos are hardy shippers: each is bagged in oxygen-charged water inside a polystyrene-insulated box, sent midweek by a licensed live-animal courier so it never sits over a weekend. Every order is covered by our live arrival guarantee. To claim, email your order number and clear photos on the day your order arrives. An unboxing video is optional.

Watch: Catfish & Plecos in 60 seconds

Short clips from our own channel — the things keepers most often get wrong, answered in a minute.

You bought it to clean your tank. It's the messiest fish you ownA common pleco eats less algae than a snail, grows to around 60 cm and produces more waste than the rest of the tank combined.
The catfish you can see straight throughA glass catfish is transparent enough to read its anatomy from outside — the spine, the ribs and the silvered organ sac behind the gills.
The only fish that never raises its own youngThe cuckoo catfish of Lake Tanganyika lays its eggs among a mouthbrooding cichlid's clutch — the only obligate brood parasite among fish.
