Finaly I have my precious pleco's at home

They are L134, L66 and L333. They are all breeding groups and are lent to me to learn about breeding these beautiful fish.
I have only got experience with corydoras and have much to learn about keeping pleco's.
For now my biggest question is how to feed them correctly. I read they are all carnivors, except maybe the L134, he will eat greens as well. I would like to give them home made food but I can't find any recepies. Could some one tell me how to prepare my own food or tell me were I can find recepies? Please

And I would like to know what is the best dried pellets to give them. I now have OSI shrimp pellets wich I use for my cory's. Is this also good for my pleco's?
Thanks!
