No im just worried about getting a dwarf zebra lion and then going out of town the next day. I have heard feeding these guys can be difficult.

get an ARCer to tank sit for you!

I've got one... He's great. What you need to do is get a bunch of ghost shrimp to keep him full while you're gone. That'll keep him going for a few days, then when you get back try taunting him with frozen foods. He'll be pretty hungry he might just go for some tantalizing mysis!
