Clown Pleco

Panaqolus maccus

Also known as L104, Ringlet Pleco

Edited by Ivan F. · Reviewed

Beginner verdict

A small, wood-eating pleco with bold stripes that stays far smaller than the common pleco. It spends its days tucked into driftwood and comes out at dusk. Without real wood in the tank it cannot thrive, so treat driftwood as part of its diet, not decoration.

Common tank-mate questions

Clown Pleco feeding and care

How to feed

  • Keep several pieces of driftwood in the tank at all times.
  • Add blanched zucchini or squash, and sinking wafers after dark.
  • Feed small portions you can see finished within a couple of minutes, because overfeeding fouls the water fast.

Telling males from females

Males often have bristly odontodes along the rear body and fins. Females are smoother and rounder when viewed from above.

Clown Pleco care mistakes to avoid

  1. Plan on one as the centerpiece of the tank, and read the tank-mate lists before adding others.
  2. Add real driftwood. It rasps wood as part of its diet and will decline without it.
  3. Expect lots of fine waste, because wood-eating fish produce plenty of it.
  4. Give multiple fish their own caves, since they may guard territories.
  5. Check your tank before you buy. Our sourced minimum is 20 US gallons.

Where to buy Clown Pleco

We have not found a store that sells Clown Pleco under its scientific name yet. We add stores as we confirm them.

Live animals and plants travel by courier. Check the store's live-arrival guarantee, and only buy once your tank has cycled (see how to cycle a fish tank).

Some US states restrict certain species. Check our US state aquarium rules table and your state's own rules before you buy.

Clown Pleco FAQ

What size tank do Clown Plecos need?

Our sourced minimum is 20 US gallons (76 liters). A bigger tank is always easier to keep stable.

How many Clown Plecos should I keep?

One is fine in a tank this size. Add more only with plenty of extra room and cover.

What can live with Clown Plecos?

Good matches on our list include Neon Tetra, Cardinal Tetra and Black Neon Tetra. Avoid White Cloud Mountain Minnow and Endler's Livebearer.

How long do Clown Plecos live?

Care guides report about 10–12 years. Stable water and a good diet make the biggest difference.

Does a clown pleco eat algae?

Only a little. It mostly eats wood and the biofilm on it, so it should not be bought as an algae cleaner.
