Bristlenose Pleco tank mates
Bristlenose tank mates are mostly about leaving the wood and the vegetables alone. These plecos stay small enough for a planted community, graze biofilm honestly, and ignore midwater fish that ignore them. The failures are predictable: common plecos sold as the same fish, large territorial cichlids that pin them at feeding time, and bare tanks with no driftwood so they starve on algae myths. Pair with peaceful schoolers and other calm bottom staff. Skip anything that treats a 12 cm armoured catfish as competition for caves.
Common mistakeSkipping driftwood is the mistake that defines poor bristlenose ownership. Without wood to rasp, fish lose condition and face higher bloat risk even if wafers are offered. Add real wood before you add the fish, and keep a cave the male can claim. Algae alone will not carry them.
