Hey everyone, n00b here. Been browsing the site for a few days. My girlfriend and I would love to start a viv or a paludarium. I want darts, she wants a turtle. Lol

I built an 80 gallon glass tank, 34" long, 24 wide and 24 high. I want to be able to walk all the way around it, so im not going to have a background. I was kind of thinking 2 small ponds, on opposite corners, fed by their own waterfalls. Then I was thinking a fake volcano in the middle with the humidifier plumbed into it so it looks like its smoking. Im not sure what kind of frogs I want, but im loving the looks of these. Dendrobates auratus 'Nicaraguan Green & Black' | Josh's Frogs

If I get those, how many do you think I should go with? Im sure ill have lots more questions. Thanks in advance!
