Hi everyone! After doing some research, I realized my 3 medium crabs in a 20 gallon high wasn't going to work... So I've upgraded them!
The substrate (6in deep, 7in on sides) is eco earth with a bit of sand mixed in. I know there could be a higher ratio of sand, but my crabs don't seem to like the sandier soil very much..
I'm still saving up for a good hood heating lamp, so for right now they have a regular 20gal aquarium light and two heater pads (one on either side of the tank). There are deep freshwater and a saltwater pools with grips for them to get in an out of, a sphangum moss pit, a sand pit, and the netting/show caddies for them to climb in. I want to eventually put some fake foliage around the back wall and a bridge from the shower caddies to the middle net hammock. Is there anything I'm missing? Food dish isn't in the picture but I promise I have one
