Hey guys, i decided to go with the Pvc idea, because i can't cut Terra-cotta pots worth beans, as i have little strength, so hopefully soon we'll get a scanner and I will post pics of my Pvc pipe cave! I got a really mongo black one that is just perfect for the tank I have, and while I was at Home depot, I noticed all sorts of hamongo ones that were just so mongo, so I thought to my self, instead of a 20 gallon tank as being my next upgrade, I'm going to do a 30, because there were so many shapes and sizes, and many had lots of extra pipes attatched, and I just know that my Axolotls would have a ball just exploring and playing in them! I had so much fun just picking the one out! I really Recommend to anyone having time take up this prodject, it is just so darn fun! Thanks for the ideas Kim and Cynthia! You guys are so clever! And the really good part of it is, is that most of the pipes are really cheap, only a couple of cents or dollars, isnt that neat? I have never had more fun with an Aquarium set up, thanks again so much guys! It took me so long just to pick out the one I wanted there were so many to chose from! Home Depot has a really great selection.
