The peppermint catfish is an Ancistrus species that is a bit different from all the regular brown bristlenoses. It has a jet blck body pricked with tiny bright white dots. The edge of the tail fin is also white in color.

Like other ancistrus the fish can grow bristles from above it's mouth. Males tend to get more while females will sometimes have none at all.

The peppermint is known to be more aggressive than many bristlenose catfish. They will regulaly fight amongst themselves and with other fish. These scrapes are rarely fatal but can result in fin damage. These tars will generally heal quickly in well cared for fish.

Feed these catfish on algae wafers and occasional frozen foods. Vegetables are also eaten. Pumpkin and green produce are good additions to their diet. Remember to provide some wood to chew as this is essential for their digestion.
