Don't know if this is the right place to post this but here goes.....I have been keeping my Theraphosa Blondi on potting soil is this ok? I was thinking of adding pete moss but the only kind I can find has miracle grow added to it. I don't know if this would be bad for me T. Blondi but I'm guessing yes so I didn't add it. Am I correct? Also the soil I used is organic. I assume thats better. I figure they are naturally found in soil environment/rainforrest so I did not add sand or any wood products. I also cut a plastic plant pot and laid in she can hide in there. Plus few plastic plants its 20 gallon long tank. Thanks for any advice or suggestions.
