One peculiarity I have noticed among many East Asian hobbyists is that they put a Tang, usually a Yellow or Regal Blue (often both), as the FIRST fish in their tanks even when the tanks are like 2 foot long. I’m not sure whether they intend to rehouse / rehome then once they get larger or give them away, but the sight of a Regal Blue in a very undersized tank for them just makes me facepalm. Deep inside I’m cringing hard and I’m like “hey do you know that thing’s gonna get to a foot long and requires ideally 7-8 foot or more of swimming space?”
I’d be totally fine with putting a Foxface as among my first fish and I do intend to put in a OSFF and a pair of Ocellaris Clowns as my first three fish. However, I would strongly prefer my tank to have more of an algae bloom before I’d put in any Tang. I know one guy who keeps a Yellow and a Regal Blue in an 80 (cm) cube. He keeps complaining that the Regal Blue gets sick with ick all the time (somehow his Yellow is ok).
Sometimes the more business-oriented LFS in China and Taiwan randomly stock their customers’ tanks because their customers usually have no idea what they’re doing when it comes to the hobby. They’re not hobbyists, they just want something that looks nice and hopefully exotic in their office or hotel lobby or whatever. Sure I mean I’d welcome their money because I have to admit it’s often these ignorant people that are some of the greatest financial benefactors to the hobby, but from the perspective of a hobbyist I can’t help but point out: “Dude, if you want a community tank, a nice reef where the fish are swimming happily and getting along, do you know what it means to put that Six-Line Wrasse in so early?” I guess 99% of them just don’t care. I wouldn’t mind them being generous with their money though, if only they’d share some of theirs with me.
When I was a kid in Vancouver, the dentist place I often went to in Parker Place had tangs (Yellow and Regal Blue) and a LIONFISH all in a nano tank that was built into a wall.
Some people, listening to the very bad advice given by shady LFS or online sellers where I am use Tangs to CYCLE a tank. First of all I’d stay away from anyone that advises using fish to cycle a tank.
Another local hobbyist put it this way: “Rich people don’t care about what they do with their fish, which fish they buy, and the quality of their fish. They just buy whatever looks good and keep replacing.” I can bet if a hotel here has a saltwater tank, the hotel manager has got absolutely no idea how to keep the fish inside.
I can bet if one of these people saw a trio of Moorish Idols in a 75-gallon they’d just go: “Oh that looks nice for the lobby / office / whatever.”
