So I just bought 2 beautiful BN pleacos from Captain bob yesterday, http://www.captainbobsfishtales.com/, and I am not too knowledgable about their behaviors. They look healthy and great but all day today they both took over a hollowed out log and did not come out. Is it normal for plecos to just stay in a hollow log all day long? I think i saw the female once today on the glass feeding.
