bristlenose plecos love fresh, shortly micro'd zuchini/cucumbers. they also love algae wafers. make sure you're feeding them something everyday.
hon, there is a whole board here about plecos. there are other boards as well. before buying any kind of fish, sit down here, search the name and learn. then decide whether or not you want to get them.
plecos in general need more than just wafers to keep them healthy. a variety of foods are necessary ranging from meaty to fresh vegetables. this does vary from pleco species to pleco species. there is a sticky about this in the plecos forum. there is also planetcatfish.com that can offer you a good guide to species, sizes and care based on a specific type of pleco.
the point isnt to just take what other people suggest and get it. its on you as a fish keeper to thoroughly find out what is necessary to care for them. if you get confused, then its a good idea to jump on the board and ask a question. i dont care what anyone says, there is no such thing as a stupid question. it can be kind of repetitive, but if you research first, then ask you will be able to articulate a good question AND you will understand more what people are talking about when they respond
