I finally got my pair of collardes on sat and the are so cool,
but i have just finshed building there permanent tank and have built a fake wall on the back and sides with morter and i think it looks pretty cool. The only problem is that i have a felling the morter will crumble when they jump about, any ideas as to what to coat the morter with to make it more hardy and solid so it womt crumble or fall to bits?
