Been around discus for a long while, kept them for years, and am a member of simplydiscus.com, where many of the experts are members.
That forum (where they are sponsors) has a good number of very reputable, experienced, long-term suppliers of high quality, healthy, well-shaped discus, but I can't recall ever hearing anybody recommend 'somethingsfishy' as a source for good discus.
They seem to have a lot of very small discus for reasonable prices but if you're just getting started with discus, you shouldn't be buying 2" fish - they're just babies and require a great deal of care and attention to grow them out properly in a BB tank.
And Axcid, you're right, if you can't see the discus you'd be getting, you shouldn't be buying them.
If you're located mid-west to east coast, the place to get discus is Hans' discus in Baltimore, Maryland, a top-notch importer of high quality discus.
If you're nearer to the west coast, the best source of superb quality discus is Kenny's discus (Kenny Cheung) of Daly City, Ca. Both of these suppliers are sponsors on simply discus, and many, many discus people get their fish from them, and are more than satisfied.
Kenny has 'Forrest' of Malaysia discus, one of the top breeders/exporters in the world. I buy nothing but Forrrest discus here in Canada, now supplied by Canadian Aqua Farm in Vancouver, B.C.
Those are my suggestions, but depending on where you're located, I may be able to direct you to good, nearer sources.
