Over the last couple of weeks I've noticed that large spaces have appeared underneath driftwood in my tank. These spaces are large enough for my full grown cories and BN plecos to hang out in. I have two thermometers in there , the bases are buried in the gravel, and they have been displaced too. I have small community fish and the plecos are the only ones I can think are able to do this. Does anyone know if this is typical pleco behavior?
