L201 digging - I'm concerned

[Complecs]

I hope I've posted this in the right section.

I've got a baby L201 and a baby L204 sharing a tank at the moment; 90l, sand/gravel/laterire mix substrate, live plants, two large pieces of bogwood, tank temp: 25*C, they are the only fish in this tank

Both Pl*cs seem to get on very well and often share the same piece of bogwood, it's just I've noticed at night Spot the L201 seems to be digging holes in the corners of the tank, the holes are quite large too. The sand and laterite outweigh the gravel in the substrate mix, so it is quite light so I'd hope no damage is being caused to him by doing this, thing is I just wondered why he's doing it

Though the pl*cs get on, I do make sure territories are clear with regard feeding and they are able to establish their own territories within the tank too. I refer to Spot as 'he' but I dont actually know the sexing of either fish

digging is natural behavior for most of the Loricariids

nothing to worry about!

You may want to try adding more of a rock cave/structure for the

Hypancistrus contradens

(L201) as it may have a preference for rock over wood to make it feel more secure.
