Nothing elaborate. Just don't have any other tanks. So it's in a decent sized tupperware with a pvc elbow in there which he kinda cuddles against. Change out some water every couple of days. Will see how the shrimp goes.Sounds like it’s stressed, or about to molt. Some won’t eat for a week prior to a molt. How are you housing it?
Turn out the lights, don’t do big water changes an give it somewhere it feels like it’s safe and hiding, usually for a smasher a small PVC pipe, not super big for a small guy like that.
