The original fish was sold for much less than that, and carried the deal that babies would be sold back.
Those babies sold for lots of money on Ebay. First pair went for $16k
Sea and reef bought one of them. Paired it up with a spawning female from PNG that they had waiting. Shortly after they had spawns, which resulted in hundreds of lightnings.
The lightnings available now do not look like the original. This is because the stripes recede with age, and the older they get, the better the pattern becomes. In 3-5 years, the babies you see now will look very much like the original lightning. Older lightning offspring that have developed the same pattern as the original will likely sell for a lot more than what was paid for them.
