I have an LFS that does similar, likes to buy things because they are “cool” but then I think to myself how many are actually going to buy that also because it’s “cool” and not have the proper experience or setup to responsibly care for it. I find it irresponsible. Aggravating to me because it’s such a great shop and they have so many great beautiful saltwater fish and freshwater, as well as corals and plants for the hobbyists, they have no need to buy those “cool” fish, other than for them to say “look at how cool this is!”. I’m not a fan of that type of thing personally.
In my opinion, if someone truly wants that different, not typically stocked “cool” fish, that customer will ask for it and ask them to order it for them and them only. They don’t need to just buy it to keep in their store for any random joe off the street with an inadequate setup to care for it to come in and buy.
They’ve done the blue ring octopus before and the stonefish, although I will say that with those, I guess they have gone about it the right way if there is a right way. They have at least only sold those to those who will sign a release form acknowledging they know what they are and the risks being taken to own one.
