Extra five gallon tank options I'm planning. Don't know what my store will have. I'm hoping they have fancy guppies but never know. Anyways I need to know if either of them require a hiding spot like betta do. I only have a cave for my betta and I'm making a list of what I need for whatever I end up putting in the my other tank. My last option is another betta but I'm really hoping for guppies. So yeah. Should I add like a hiding decoration onto my list for any of those?
