im not so much into frogs. but i have seen some really nice vivariums. the tank with the black background is actually automotive window tint. this is the second tank ive done it too. i think it looks great. i have a thread in DIY about it as well as pics of my other tank.
This configuration is my favorite layout of the ones that you have pictured.
Is it just river stones and a weathered tree branch on black sand? It looks great, and I've been thinking about doing something similar but didn't know where to start.
Yup. thats it. its really simple just be creative. im possibly adding plants to it today but only live ones. its a manzanita branch. if you live anywhere you can find them in nature as well as online. i think manzanita is some of the best aquarium wood. i would have loved if it still had its red bark but ohwell maybe next time.
