Tim, I was just picking up on what BigJay had mentioned in his post when he said "Some people will pay and pay dearly to have a one of a kind. I really want that black angler they have there but the wife would kill me." So, I am not "completely wrong" in what I was saying. There are species that are being captured that are truely "rare". I agree with you on the points you make, however, there are other issues that come from this. First, to use your words,
...They are extremely hard to catch, i.e very deep water. Which is the case for Boylei, Sunset Wrasse, and many others. Not many, if maybe a dozen people in the world have the skill to dive to 300' plus to collect these fish properly and then bring them up correctly. Also many fish that are expensive and so called "rare" are found in mostly protected areas where collecting is prohibted.
That is part of my point on this, they come from very deep waters where they are in an environment we cannot duplicate in our relatively small tanks. And also, as many skilled divers that are able to correctly capture them, there are 10 more that are collecting with questionable means and also violate the protected areas creating a blackmarket for them because they know they can get some great money from it.
I started in this hobby in the Mid 80's after I got out of the Air Force. I had served in Japan and Okinawa where I learned to SCUBA dive. I fell in love right then and there with ocean life. During that time, there were advances being made in the aquatic industry that allowed us to keep more delicate species, but there wasn't a whole lot of knowledge about how to keep them alive. Many LFS's were carrying species such as sharks, octopus, eels, Moorish Idols, etc. that nobody was able to sustain and would die within a couple weeks. All this because we didn't have the knowledge of what they needed. In 1986, an LFS owner that I became friends with, got in a rare fish known as Monocentris japonica (Japanese Pineapple Fish). He brought in 12 of these and they were larger adults about 6". He offered one to me for $125.00. I had 4 tanks at that time and had the "perfect home" for it and I grabbed it up. Two weeks later, he was dead. I talked with him about this and found out that the four he had left had died as well, as did all the other one's he sold. Our knowledge at the time was so limited, we did not know the first thing about keeping them other than the fact that they looked really cool!
Granted, today our knowledge and technology has vastly improved, but yet, there are only a few people that have had success in keeping Moorish Idols. They are cheap to buy as they are common on the reefs, but does that mean we should all go out and get one? No. They have very specific needs that no one has been able to successfully replicate. Yet, too many newbies to the hobby jump in and buy them and throw them into tanks they think are mature after only one week! This is my point. There are several people on Reef Sanctuary that have the experience and patience and knowledge to be successful in keeping these fish, but there are many, many individuals out in the marketplace that don't and ultimately kill everything they put in their tanks because they didn't take the time to find out what their needs are. Same is true for these "rare" fish that come from deep waters, we just cannot replicate their natural environment and in turn, shorten their lives considerably. More experienced reefers may have better success with them than inexperienced ones. That is why I just feel that perhaps it is best to just leave these fish where they are, where we can go SCUBA diving and view them in their natural surroundings.
