Good day folks, bout to begin my first frog habitat and I have a couple questions. What’s the better medium for the background? A painted/sealed pond expanding foam, coconut husk over silicone, or hygrolon covered foam. I think short term the painted foam background would look better, but perhaps the hygrolon would grow moss better and ultimately look better in the long run. Could I grow a moss or plant background just as successfully without the hygrolon? I’m struggling between the 2: hygrolon or non hygrolon? What y’all experts reckon?
