Behaviour and habits

The clown pleco is a small, striped suckermouth catfish that stays manageable, unlike the giant common pleco that outgrows most tanks. It is peaceful and nocturnal, claiming a cave or a piece of driftwood as its own and rarely bothering tankmates, emerging at night to rasp at wood and graze the surfaces. It is not a schooling fish, so a single specimen is normal, and it is happiest in a quiet, planted tank with plenty of wood.

What to feed, and how often

A wood-rasping herbivore, it needs driftwood to graze on for digestion, plus sinking algae wafers and blanched courgette. Feed in the evening so it can work through the night, and do not expect it to live on leftovers alone — a piece of wood and regular vegetables keep it healthy.

Water changes and maintenance

Change about 25% weekly with a gentle vacuum. Although smaller than a common pleco, it still produces a fair amount of waste, so keep the water clean and nitrate low, and leave the driftwood in permanently.

Care and how easy it is

Hardy and smaller than most plecos, but it still needs wood, a cave and a tank sized for its adult length of around 10 cm.

Common health problems

Robust; problems come from a poor diet (a thin, sunken belly) or from dirty water.

If it gets sick

Feed wood and vegetables, keep the water clean, and act early if the fish thins or hides more than usual.
