That is the scientific number it was given. Some folks call it a snowball pleco. Some sources say it gets 10 inches, others say a foot. If you want a pleco, look into the bristlenoses for your tank. I particularly like the bristlenose sometimes called medusa. Dino has some beautiful bristlenoses and breeds them. I think the l number is 107. Go to the link below to learn more about my baby, then stay on that site and go to Cat-eLog type in L107 and it should take you right to it.Isabella said:P.S. What is "LDA33" ?
