Can two different types of plecostomus breed?

have a regular plec about 7 inches long and was given a female albino.....albino dissapeared for about 2 weeks,thought she had been eaten as i have 4 angels.3 weeks later albino started to appear on a regular basis and approx 4 weeks after getting it i have a baby plec which has somehow survived the angels...did put it in a breeder but it escaped so i have decided to let it take itschances under the rock it hides under....dont know if there are any more or more to come but guess thje answer to your question is yes
