My collection has 2 parts that are equally important to me:
1) My 580G and 270G show tanks that I keep about 45 plecos just to sit and watch and enjoy. They are setup so I can see them and not optimum for them.
2) About 90 other plecos in 11 tanks setup as species breeding or growout tanks. They are setup for the pleco's comfort and not my viewing. I the next couple of years I hope to give back to the community some rare pleco babies. Like most other pleco lovers we try to breed them to assure their survival and not make money.
