Hi there I'm looking at building my beardy a new tank as the one I adopted him in isn't suitable I was just wondering if anyone can offer me any tips as it's the first time I've tried anything like this and I'm new to dragons so what I'm really tring to decide is what wood to use to build the tank I want something light but sturdy nothing overly expensive in case I make a mistake or dose anyone recommend any cheap wood for a trial run first ? Also what can I use to make a substrate I heard about shelf liner with sand and rubble but how do I get the sand and rubble to stick and also do I need to keep changing this or can I just wash it ? Any other tips advise would be much appreciated thanks in advance also I live in the uk
