When i was there they just told me umbee and no one mentioned dwarf to me they look like they are stunted to me and the color is really weak i thought it was a low grade fh looking hybrid of some sort at first glance. I evan asked the guy when are u getting some umbee's in he says we got a proven pair right here and i thought to myself those don't look like any umbee i have seen. Now this lfs has gotten in umbee's befor some years ago and they looked great but i could not get any because i was fully stocked but doh! So i don't know if they trying to pull a fast 1 on u or not like u said at 2 they are pretty good most of the time i don't know what to think of the so called umbee pair but they won't be coming to my tanks that's for sure.
