I am trying to understand this question about alpha. Everybody here is telling you that you shouldn't house two beardies together so your question about alpha doesn't make sense. My question is though why have a second beardie if you can't even afford all the other stuff for the tank??? Are you going to be able to afford all the crickets/dubias and other food that this beardie is goig to eat? Sorry to the OP and I don't mean to be rude or ugly so please excuse me if it sounds that way. No disrespect intended here at all. I would have made sure I could afford a second beardie and I had everything in place first before buying the beardie. Even if you rescued it or someone gave it to you. As everyone knows here keeping one beardie let lone two can be and is expensive. I also know that beardies pull at our heartstrings and we just jump in sometimes without thinking first.
I've done it myself, not with beardies though. Just my humble opinion though!!
