Around me, and even on this board, folks saw the super high prices during/after COVID and many decided to become basement reefers. By the time that they all got set up and had things to sell, demand for named corals has waned a bit, more competition has arrived and other prices have fallen.
A few of the basement reefers around me bring in fish wholesale since these prices are more stable. The basement folks can undercut a LFS fish sales with their super low overhead.
This all happened after the nemo/biocube generation jump started the hobby... stores, home sellers, etc popped up everywhere and the next downturn took many of them out. The oversupply that some of us are talking about is a warning sign. The stores and basement hobbyists that make it through the downturn with stock to sell on the other side will come out well because it takes time for new entrepreneurs to set up, grow and be able to sell.
