Are these guys healthy?

Thanks for the info, I'll check for chloramine and treat if necessary. I guess Stress Coat would do the job? The 'tap safe' I talk about is a product I use for my aquarium water, let me check the box... ok, that was pointless. "takes harmful chemicals out of tap water" is the most detailled information in there! Very specific :happy:

With regards to shell grit, is it simply a matter of adding it to the tank, getting the pH right, and then leaving it be? Water changes can then be done with normal dechlorinated water and the grit will maintain the levels? I had hoped to use a sand substrate anyway so perhaps coral sand would be the choice.
