Thank you very much for your help!
I have a 20L tank at home that I can stick him/her in for the time being until I can set up a full adult home. Although I was hoping s/he'd be something smaller, I suppose I can handle a bullfrog.My boyfriend isn't too happy about the additional aquarium in the house but he seems to like the little frogling already. I'm actually pretty excited, since it's a new area of pet care I haven't tried yet!
