I know that this has taken me way longer than I expected, but I'm nearly ready to add water and start cycling it - just in time for the school year to end - but it will be easier to care for the critters over the summer if they are in a bigger tank. (I'm going to add the gold fish back to the tank, along with the feeders so that I can have one less tank to worry about over the summer.)
On another note, the male crab has now molted and seems to be doing well. Not sure if the female was bread duriong her last molt, will have to wait and see.
Here is a picture of the little progress that I've made.
