Hey guys, I just bought another 20 gallon long tank, and I have yet to set it up. It's going to be home to some peacock gudgeons and I think male guppies, but I have no idea how I want to decorate it. I know I'll need lots of caves and hiding places for the gudgeons, but I'm not sure how to incorporate that in a way that looks natural. Any suggestions or pictures of your own tanks would be greatly appreciated. Thanks in advance!!!
