I agree with starting them out in a qt tank. I currently have 5 of them in my 40 qt tank. Received them direct wholesale. They started eating frozen brine first by the second day. Now I think they like mysis best so far. I originally started with 6 but one didnt survive the first week. I love these little guys, they are now swimming up to where I stand and beg for food. I run hypo for qt and have read where lower salinity increases their appetite so that might be also helping out.
