Ok I may have made a dumb mistake. I have a 150 gallon and I'm getting sick of having to scrub the algae off the glass every week. So Friday I went and got 3 really small common pleco's. While I was there they finally had sengal bichirs in so I bought one hes only about 3 or 4 inches right now. Well today I got to thinking that I had read some were that bichirs and pleco's don't go good together because the pleco could start sucking on his slim coat. So far the damn plecos haven't cleaned anything which is pissing me off. Anyways do you think I should return the plecos, I havent seen the bichir for a couple days he just stays in the cave the whole time. I checked a couple days ago and hes just chilling in the cave. Gonna check on him again tommorrow.
