Steve,
With the recent surge in interest among seasoned marine enthusiasts for smaller deepwater Basslets and Grammas, its no wonder fish like the Bicolored Heliotrope Basslet Lipogramma klayi, Threelined Basslet Lipogramma trilineatas, and the Royal Basslet Lipogramma regiaare are now being recognized more frequently. All three of these fish are incredibly beautiful, but unfortunately are rarely ever seen in the aquarium trade. If these fish do show up they fetch upwards of a thousand dollars or more.
Like all very deep dwelling fish, these Caribbean endemics are found in very deep water ranging from 200-400 feet deep. As you know, diving to these depths is very risky, and requires a very experienced team of experienced divers who utilize mixed gas rebreathers. There are only a handful of fish collectors across the world, and only a few in South Florida who occasionally dive to these depths to harvest more cryptic fish.
Like many other infrequently available species, if and when any of these fish were to become available I will surely try and obtain some.
Happy Fishkeeping!
