That is the problem with most high end corals, eventually the market gets flooded. I was told by a coral farmer once that just your regular/staples corals will make more money because their are not allot of people willing to shell out the big bucks. What happens here on reef2reef is not what happens in a majority of the hobby. Some people will order one high end but but several 30 or 40 dollar corals.
What is weird is the Colorado sunburst have stayed pretty high priced so far compared to most. I think anemones are harder than corals though.
Like most things in this hobby, interest and demand soar and wane.
You're right, the CSB has stayed high, and slowly creeping higher. They do have decent mortality rates though, so a lot of people kill them. Perhaps that affects the supply side of that equation.
Truly aquacultured anemones are in high demand right now. The wilds have subsided a bit with the Indonesian halt on exports which is not a terrible thing as a lot of wilds tend to morph colors under our tank lights. Basically, it was a good way to sell straight from export and odds are they don't keep their colors but by then, the vendor has made their money already.
I fully support buying aquacultured strains and farming them. Less pressure on wild colonies and they have already been acclimated to tank life. My farming has easily paid for the hobby... heck, it buys me groceries too.
The hardest thing to do is find legitimate, lineaged strains. Everyone is selling Inferno this or Sunburst that, when it's not the original. Make sure your source is legit so you can make sure you are selling legit splits to other reefers. We all owe it to each other to do that.
Locally, I agree with the statement that bread and butter sells all day and makes more money. Nationally though, when you can ship and willing to, high end wins out all day. Why waste my space in my frag tank growing rainbows for $50/anemone when I can expend the same energy and resources to grow $1200 CSBs? Do I sell them locally? Not too much, not enough BTA lovers that would pay that price for it locally... but I can sell them all day long nationally.
