i have a log cave il going to use and several pieces of driftwood...also should i put a piece of glass in it to make a water area of should i just use a large container?
I'd change it every couple of days or as soon as your Tiger Sal gets it all dirty. It's always important to keep the water very clean when dealing with sensitive skinned amphibians. The only amphibian I have at the moment is a Pyxie Frog and I change his water every day.
