Love the Tessalata in your avatar - by far and away one of my favorite eels. I have two Fimbriated eels in my 265 gallon tank in the living room, which are mildly similar in appearance, but nowhere near that manner of disposition. I'm planning on putting a tessie in my big shark tank. But that's going off on a tangent. And yes, I'm new to sharks.
You all make valid points in regards to supply/demand for our favorite pets. It is a shame that there are so many disreputable LFS out there that will sell whatever to whomever. After quite a search, I've been VERY fortunate to find a very well regarded store near me - I knew I was in the right place when I inquired after the two blacktips for sale, and their first question was, "Do you have at least a 2000 gallon tank right now? And do you have plans for an even larger tank? If not, don't even bother asking further - we won't sell them to you." And once I pointed out that I had both, they've been wonerful. They're selection is amazing, and the fish all look healthy. Likewise, there are two LFS that have various types of sharks who are more than happy to sell smoothhounds and claim they'll be happy in 150 gallon tanks for their lives.
Unfortunately, people will continue to purchase exotic pets, and there will always be a supplier for any desire. The best solution is that of education - it's our responsibility to help novice keepers, and not admonish even foolish keepers. There are inevitably going to be people who desperately want to keep a shark in a small tank. Odds are good that they've been fed tripe by their LFS, and it's much easier (and rightly so, generally) to believe a person with whom you can talk in person, rather than a faceless opinion behind a keyboard. As such, we can't immediately call a keeper an idiot or a "noob" (I abhor that term, it's so condescending) when they question information found here.
Lastly, well worded responses featuring legible spelling and grammar are always a huge help, and a definite sign of intelligent replies. No matter the character of a reply, if I have to take out an internet to english dictionary to understand what's being said, I don't take it seriously.
T-3 weeks til my tank is ready.
