No. Research is a systematic investigation. You are simply asking others to answer your questions for you.-Shane
Wouldn't that make most research just getting answers from other people. Most research is either done on the internet or in the library. Other people wrote all the books and info on the net. Hear we just get it from people in a more direct manner. No answer can be found without a question, and no question can be raised without inspiration.
I guess it could be said that this person just came here for some inspiration.
BWT, my favorite plecos are Albino Bristle nose, Starlight Ancistrus, Peppermint Pleco, and Clown Pleco. Any of these would keep a tank pretty clean, relative to their size of course. I would also pick one that is similar in size to the other fish so they don't get picked on to much.
Also, I see plecos as a symbiotic relationship. I provide them with a friendly environment, and they keep that environment clean. The occasions that I actually see the dam things are an added bonus (holy ****, he's still alive).
