I would like to have a pygmy angel. Right now my only saltwater tank is a 14 gallon biocube reef. Can I happily house a pygmy angel in my tank? Or should I just wait until I eventually set up another (bigger) tank? I don't want to be like the person I saw on youtube that had 2 yellow tangs in a 3 gallon and was completely unaware of what was wrong with that, so I thought I'd ask for opinions before I went out and got one.
