sound like a good thing to try but my bp hasnt even been in his hides yet.i was going to buy a bigger one for 25 bucks but i got some moss instead and put it in the hides so im going to see what happens i might take the top off one hide and see if he lays there then maybe cover it when he starts using it more.hes about 22inches long and about inch wide maybe wider.i have had him since sunday so almost a week.he ate with no problem so i think hes pretty adjusted to his tank but he wont hide inside his caves just behind them
