Wow! Sound like quite the project, but the upside is you can have fun raising fish, and event earn an income for them! Yipee for breeding bettas! Your tank looks really cool, it looks bigger then 16 gallons to me I like how it kind of reminds me of a little swamp or something! I just realized this, but when I clicked the link to your paludarium from your signature, it linked me to edit your profile. Just wondering if you've noticed this.
