Overview
The clown pleco is a small armored catfish from the rivers of Venezuela and Colombia in South America. Unlike the giant common pleco, this little fish stays around three to four inches long, which makes it perfect for smaller tanks. Its body is covered in wavy cream and dark brown stripes, a bit like a tiger crossed with a zebra.
One of the coolest things about the clown pleco is its diet. It is a true wood-eater, and it needs pieces of driftwood in its tank to rasp on with its special mouth. Chewing the wood helps its digestion and keeps its belly full. During the day it hides, then comes out at night to graze quietly along the bottom.

Water and tank
A single clown pleco is happy in a tank of about 20 gallons. The water should be warm and clean, with gentle to moderate flow. These catfish are hardy and forgiving, which makes them a good choice for keepers who are still learning.
Aquascape and setup
Driftwood is not optional for a clown pleco, it is a must. Add at least one or two chunky pieces for the fish to graze on and hide under. Caves, rocks, and shady plants give it the dark daytime hideouts it loves, since it is mostly active after the lights go out.
Diet
In the wild it eats wood fiber and the tiny bits of algae and food trapped in the grain. In a tank, offer algae wafers, sinking pellets, and blanched vegetables like cucumber and zucchini, but always keep driftwood available for it to chew.
Tankmates and temperament
The clown pleco is peaceful and minds its own business. It makes a great tankmate for tetras, rasboras, dwarf cichlids, and other calm community fish. It can be a little territorial with other bottom-dwellers, so give it its own cave to call home.
A shy night grazer
Do not worry if you rarely see your clown pleco during the day. It is naturally shy and nocturnal, spending daylight tucked into wood and shade. Turn the lights down in the evening and you may catch it out scraping happily along a log.

Frequently asked questions
Does a clown pleco really need driftwood?
Yes. Clown plecos rasp on and digest wood as part of their natural diet, so a tank without driftwood is not a good home for them. Always include at least one solid piece.
Will a clown pleco keep my tank clean of algae?
It will nibble some algae, but it is not a strong algae eater. Think of it as a driftwood grazer that needs its own food, not a cleanup machine for a dirty tank.
How big do clown plecos get?
Only about 3 to 4 inches, which is small for a pleco. That makes them a good fit for tanks around 20 gallons, unlike the common pleco that grows over a foot long.
Why do I never see my clown pleco?
They are shy and mostly active at night. Provide caves and driftwood, and watch after dark or during dim evening light to spot them grazing.
