I have been thinking of trying a plastic tub habitat for my crabs, I wanna get bigger and better but I don't want more glass in my sons room. So, I was thinking of getting one of those really big plastic storage bins, drilling holes in the top for ventilation, filling it partly up with sand and using that. Anyone have any pros or cons for this? (I'll get one of the clearish ones so there is still a day/night difference in lighting for them)I think it would keep the humidity in great, I wouldn't have to worry about it breaking and it would maybe seem safer to them than being out in the "open" like in a glass tank? The only thing I'm not sure of is if a heat lamp will heat it safely and efficiently? I use this for some of my snakes, so it seems like it would be fine for the crabs, too. I am pretty sure I can't use a UTH cause it would be on plastic. Anyone have a better idea for heating? Thanks!
