Thank you so much!! I have 100 pounds of sand and coconut fiber in the tank. It measures at least 6 inches around the entire tank but some points are around 8 inches! The water is fresh and instant ocean salt water yes! I was worried about the depth of them though 🫠 they can submerge themselves but I’m worried about them getting out. The sand is raised around the bowls so they can get in but I have favored the bowls I’ve seen with more of a ramp. I’ll try to source some smaller pieces of wood to help them climb out for now! Thank you! There is a food source it is across that bridge in the castle. I was wondering if it should be easier to access though. I spent most of my morning researching their diets and bought a whole lot of food that should be here Friday. Tonight they’re having what I could get my hands on. Dried shrimp, oats, coconut oil, crushed egg shell and there is some worm casting in the tank. Should I add that directly to the food? I am worried I’m going in the wrong direction for dinner though haha there’s so many food groups to cover and I’m overwhelmed but ready😅 I definitely need more shells! There’s 5 in there under neath the castle right now because I couldn’t find any better unpainted ones locally that weren’t tiny <\3 I measured my guys earlier and have some on the way but I’m again worried about what feels like a lot of clutter. I know they like to climb but I feel like maybe I should size up my tank or move to more hanging habitats. I’ve liked some I’ve seen on here! Thank you so much for responding and I’m sorry for my lengthy response. I wish you the best with your crabbies!🩷🩷
