Helfrich's firefish

[Ruth]

Does anyone have one or more of these fish or have you kept them in the past? I am getting a couple and have researched them and can't really see where they are that much different from the purple and orange firefish that are commonly seen. Like all firefish they have a tendency to go carpet surfing and don't seem to tolerate warm water that well as they are a deeper water fish.
Any one else have some advise they can offer from first hand experience?
