As for the T moss and Frog Moss, well the frog moss is sold in clumps and is in a dormant form. Once it is moistened it will begin to grow again basically re-animating the moss, but if dug up and broke apart and the frog accidentally eats a chunk the frog WILL become impacted due to them not being able to break down plant matter. The same goes for the long strands of Sphagnum moss sold as Terrarium Moss. The long strands will tangle together inside the frog's intestines along with the fecal matter causing a blockage. They can't claim that its 100% safe because its NOT. Its not fun having to extract a long strand of moss from your frog's Cloaca believe me. Luckily it wasn't a very long piece I removed. Ill never use it again.
Coconut Fiber is one of the safest substrates and I use it for all of my frogs. Mind you that it is also not 100% safe. I've found some debris within the substrate that would make you worry about using it. Eco Earth Coco Fiber is more natural than other substrates in terms of natural/safety. If eaten accidentally it almost always passes through the frog harmlessly and easily UNLESS one of those debris was missed while you sift through the soil. I've found stones larger than a quarter as well as plastic tarp strands, chunks of plastic, various sized stones, long leaves of grass, various plant seeds, Easter grass, bark, wood chips, etc.
There is no 100% safe substrate. All have some potential hazard that could occur. It is up to us to prevent these occurrences by say diligently sifting through the Eco Earth before using it for your frogs,
