How do you breed plecos and how do you sex them?

Answer 1

Males have longer pectoral and interopercular odontodes. They also have plate odontodes at the base of the caudal peduncle. Females are more rounder in the ventral region and tend to stay a bit smaller. Due to the adult size of these catfish, most successful breedings have occured in ponds with steep clay or mud banks. They dig tunnels close to the water level and the males guard the eggs until they hatch

Answer 2

Sexing plecos can be difficult, but it's not that hard. It depends on the type. Bristle-nose plecos, for example, are easy. The males will have LOTS of bushies on their nose, females will have very few. Others are close to impossible, like commons.

Anyway, you will have to provide an adequately sized tank. For the smaller types, 4-6 inches long, 60 gallons is good. For the bigger types, 12-18", you'll need at least 150 gallons. Provide overturned ceramic pots for them to spawn in, and do a large water change, like 75%. November is the best time of year, but you may be succesful at other times. The plecos will think it is the rainy season (spawning time) and the female will enter the male's territory, and they will spawn.

Edit: What Austin said is not true. I have a bunch of baby plecos running around my tank right now.
