So here's a question for those of you keeping urchins. Could I keep 2 pincushion urchins in my 46G? I'm more concerned about space than food which is why I'm asking. I picked one up tonight from a guy who didn't want it anymore and have fallen in love with them lol. I really like halloween urchins and would love to get one as well. So can I keep a purple pincushion urchin and a halloween urchin? Or would there not be enough room? Thanks guys
