By the way, what happens if they can’t dig? Don’t they act more stressed?
No the 4 that are in the sid tank couldn’t be calmer to be honest, I thought when I put them in there that it would be the last time I saw them lol but they are out and about all the time and spend quite a bit of time at the front of the tank in among the small cobbles, if they do dig that is usually were they do it to as I have seen a couple of heads popping up a few times now.
They big Horsies that I have do seem very timid and stressed when they come up out of the gravel/sand but the dwarf dont seem to be that bothered.
