As H@rry said, for coral farmers, fads are hard to stay on top of (Oregon Tort example given above). The same is not true for vendors. If chalices are selling, it is a matter of ordering more from the distributor. Those who buy what they like are still influenced by fads, as we only see what the vendors are offering for sale, and that selection is definitely affected by
market trends. Some end up buying only what survives in their tanks, which is a
market share the vendor may or may not think worth capturing.
One thought I had was that, in tougher economic times, acans might not sell as well because they are more costly. Personally, reefpets, I don't think the acan fad is over. Although they've been out a while, many don't know yet they are so hardy you can cut them to pieces and the pieces grow back. Many don't know yet they do have a lightling
and feeding requirement, with the latter contradicting what many current textbooks are saying.
The best vendor strategy I can think of is that because it is difficult to predict the next best-seller, broadening the portfolio will reduce risk (just as with financial investments).
As H@rry might say, if it stops being fun, then aim for fun.
Best of luck.:angel: p.s. It might also take some time for people to adjust to the new name.
