I have 2 ornates, 1 eastern, and 2 Russian torts all sharing a 100gl tank. I will attach a photo. Our vet says they are okay to be living together, but my concern is their bedding. They currently have organic potting soil as their bedding. We have tried Eco earth dirt which I like, coconut husk, and multiple soils. They looove to burrow and I would like to stay with something they can burrow in. My concern is each soil I use, I get bugs they multiple by dozens in he soil with them and I am afraid they will get parasites and die. I have had an ornate pass away in the past a few years ago due to parasites from bugs in my dirt. Any suggestions on bedding I can use? Vet suggests reptile carpet and moss on one end for them to burrow in. My "kids" hate reptile carpet. We've tried it before and they seem stressed because they can't burrow. I have seen Google suggestions for alfalfa pellets. My concern is they won't get much traction when walking and pellets may get lodged in their rear legs where they tuck their knees away. I need bedding that will help keep moisture well. Any Suggestions? I haven't done anything yet but want what's safest for them and something preferably where they can burrow. Mind you the photo I am posting, I have added appropriate UVB and UVA lighting since. Also was suggested that I cover the tank to keep moisture and temperature insulated.
