I have a "regular" firefish and he spends most of the time near his bolthole, but is not shy. Always the last to emerge from his bolthole, and first to retire at night, but he's out and about most of the day. Peaceful tankmates are the key. I've never seen him attempt to jump, but I have 0.25" mesh screening over the top of my tank. He's surprisingly one of the least skittish fish in my tank, but it's probably because the rest of the fish don't really pay attention to him. Only significant interaction he gets from the other fish is my Blue Flasher flashing at him from time to time.
