Bandit Corydoras – Hoplisoma metae
The Bandit Corydoras, Hoplisoma metae, is a peaceful South American cory-type catfish with a pale body, dark dorsal saddle and distinctive black “mask” running through the eye. Also known as the Masked Cory, Meta Cory or Bandit Cory, this sociable bottom-dweller is a superb choice for mature community aquariums with soft sand, clean water and calm tank mates. It is best kept in a group, where its natural foraging behaviour, gentle shoaling activity and attractive markings can be properly appreciated.

Lucas Henderson –
Bought a group of Bandit Corydoras for my 30-gallon community tank. They’re very active and peaceful, always near the bottom. The black mask is striking and they seem to enjoy the soft sand substrate. Easy to care for and blend well with my tetras and rasboras.
Jane Harris –
These fish are charming and social. I kept them in a group of six and they form a nice shoal. They don’t stir much and stay calm. Only issue is they need slightly soft water and stable temperature.

Great addition to my aquarium. The markings are unique and they’re not aggressive at all. I feed them a mix of sinking pellets and algae wafers. They thrive in a well-maintained tank with soft sand.
