Pleco for a 29 gallon?

Plecos are hard to sex when they're young. BN plecos can get to 5-6" so it might not be the best choice for a 29g. I have 2 Rubberlips (not Rubber) plecos that stay fairly small at around 4" and under $10 at most Petsmarts. Clown plecos also stay under 4" and about the same price as a Rubberlip. There's others but can be expensive and/or hard to find.

Spiderwood is a hardwood and will last for 5+ years with plecos, probably 10+ years. Malaysian driftwood is soft but will still last 5 years or more. All plecos will feed off the biofilm that grows on the driftwood. There are a few species that will feed on the wood itself but you won't have to worry about it.

Ok. Thanks!
