50g Vivarium for Fire Belly Toads

[Mudfrog]

One of my 50's cracked on the bottom. It's just in the corner and I've siliconed it but I would rather not risk filling it with water again. The wife has wanted frogs for a while so we decided to convert it to a Vivarium. It's going to be a huge tank for Fire Belly Toads but that's ok. The dimensions are 48L x 18W x 13H (a short 75g). I'm planning on doing 18" x 18" as land and 30" x 18" x 6" as water. I'm going to use large rocks, driftwood and frog moss. What should I use under the frog moss / driftwood / rocks. I have a bag of the typical brown aquarium rocks (pea size), I also have pool filter sand. I'm assuming I would go with the smaller rocks then some kind of soft base on top like coconut fiber.. Would that work? It would take a lot of coconut fiber to fill an 18x18x6 area.

I'll use this thread for my questions as well as updates

This is what I have planned. The shelf should allow an area where they will not have to float. A lot of the pictures / vids I have seen shows the toads hanging out in shallow water.

Hi,
I used large gravel and laid window screen down on top and added a mix of coco fiber and organic dirt. I used small terra cotta pots as hides and heavily planted. I used a TetraFauna with the stream, which they totally love! Your diagram looks good. Be sure and post pictures.

So they seem to prefer a stream. I could probably fab something up to work as a stream. I have plenty of room.
