Hey Tom, long time no talk!!!I want you to be aware of a few things. Just trying to arm you with knowledge.
- Spraying the coco coir does very little. That will evaporate in minutes. You need to pour water into the substrate to keep it damp. How much and how often varies a lot. Temperature and ambient humidity have a big influence on how quickly the substrate dries out.
- I think you'll find that coco coir is too messy for little sulcatas. I prefer fine grade orchid bark.
- FL is a great place for a baby to grow up. AZ is not. Kidney damage from dryness can literally happen in one day. If this baby is 40 grams, it is more than a day old. Even just a coupe of weeks of dryness is enough to doom them. She is not too young to have been ruined, I am sorry to say.
- I have found a generality over time and it relates to many subjects. People with website and marketing skills are often not the best at producing a quality product. The converse is that the people who are most skilled at producing a quality product are often not very skillful at marketing or making a good website. Just a point to ponder.
- Grass hay is good for older larger sulcatas. Its too large, rough and coarse for babies.
- Go easy with spinach. High in oxalates. A small amount once in a while is okay, just not much and not frequently.
- Hibiscus leaves are great tortoise food, but the grocery store produce isn't. Read this for food suggestions: https://tortoiseforum.org/threads/for-those-who-have-a-young-sulcata.76744/
- Your baby needs to be soaked every day. In the wild they hatch into the hot, rainy, humid, monsoon season. There are puddles, marshes and green growing food everywhere. Hydration is key to their survival. Most websites, breeders, vets, and "experts" are not aware of this and will tell people the opposite. Some people are starting to get the message that water isn't the enemy and we are seeing advice that runs the spectrum from "they get all their water from food" to "soak once a week" to "every other day" to "daily". Daily is the right answer, but not everyone has caught on to this yet.
I sincerely hope your baby is one of the survivors and was well cared for by whoever you bought it from, but I've seen so many out of AZ that aren't. Here is more explanation on what goes wrong: https://tortoiseforum.org/threads/hatchling-failure-syndrome.23493/
Forgive me for being pushy, but I see new keepers making the same mistakes and having the same misunderstandings over and over. I'm just trying to lend some experience based insight. Knowledge is power. I'm happy to answer questions, but I don't intend to comment anymore unless you request more explanation.
Dianne purchased her hatchling from me and has been given the correct info and a baby that has been soaked daily since it popped out of the shell.
