Thanks FD.
Best I can tell, it's a female Pearl due to it's rounded dorsal fin. The males have a more pointed fin. I guess they both can get ~4" long or so, but the male has a tiny bit more color to them.
It's a funny fish and occupies all layers of the tank and even pokes itself through a slot in the giant plastic driftwood, explores the hollows inside and pops back out where ever it can fit.
One of her feelers broke a few days after I got her. No idea why. A good part of it was dangling by fibers for a few days and eventually disappeared.
