plads are a bit harder to take care of.. i would recommend a dart frog tank.. andyou can breed them and sell the babies.. but a 75 gallon could hold a couple pairs. www.blackjungle.com crazy site and the DIY tank is awsome too ... and the cheapest dart frogs are about 45 dollars around the web.. but you can breed the babies and resell for a bit more being that it is local :]
