I have 1 tank in my daycare (the kids LOVE looking for them ) and 1 tank in my son's room. We're finishing the basement in a month or so so that will give me more space for frogs My husband will hate me (although I think he secretly likes them because I always catch him looking for them in the tanks )...lol. I have a few that I want to get over the next year or so. There's ALWAYS room for frogs
