Sorry I haven't responded, it's been a busy month. First, I have the plants all over the tank. Some are in glass containers suction cupped to the sides, up above the water. Others are in planters around the tank. One is on a second level, one is on a platform over the water, and some are positioned just above the substrate. I think putting rocks or shells over the soil might be a good solution. The ones that have live moss on top are disturbed last. I hate to limit their access to all the goodies deep down, but....
Also, as far as succulents go, I went with the theory that if they're ok for other inverts, amphibians and pets, they're most likely fine for the crabs. I used an aloe plant, which isn't toxic to anything, but I planted it in the sand and it eventually rotted from the dampness of the sand. I don't know the names of the other succulents. The store usually doesn't say what they are. They've never tried to eat the succulents, they just dug them up to have the bowl to themselves.
The 1st pic is the fern I originally planted. You can see how popular it was. I thought they liked hiding in the leaves, but instead it was an all-you-can-eat buffet. The next is live moss, which I find on the bottom of the tank about twice a week. On the left of the 3rd, imagine 2 Crotons, because they ate the fern and the dracena. The last one is a pic of the empty bromelied planter.
I guess I should just be happy they seem to enjoy themselves, stop by the nursery on my way home, and call it a day!
