I picked up a red foot about 3 days ago and have noticed a few things and just had a few quick questions. 1st i noticed he seems to almost pump his arms and head in diff variances. Sometimes only his arms sometimes just his head and usually the most common is both. Also, he stays in his hideout all day, if i pull him out he will eat and then go back to his hideout. Is this normal? I have a 50 gallon tank for him with a screen top. The humidity will not stabalize and I was curious if I were to add more substrate could this solve my issue. Humidity stays around 45 or so, I was shooting for like 70 if poss. Temps are perfect however. I also notice some pyramiding in his back central shell, How do I make sure it stops and doesnt get any worse because other then that he is very smooth i would like to keep him this way. Thanks! -Matthew
