XM- I guess you have yet to see L173, L236 or the, perhaps non-existent, L250. All three of these fish sell for more than zebras and, imo, outshine the L260s or any of the other B&W Hypans.
I have 173b from Aquarium Glasser (the b designation indicates it is from 173 parents but is unusually patterned- they are supposed to throw mostly normal looking 173s).
I have a pending deal to trade zebras and cash for some 236s.
Finding anything that even remotely resembles the L250 would involve lottery luck. First just to find one is akin to winning the lottery and then if you did, paying for it would probably require that you have already won the lottery
Poke around on PlanetCatfish or here for some neat pics
