The Singapore is probably commercially-raised fish, it is a large industry in SE Asia, they have the warm climate and can raise fish in outdoor ponds cheaply. Many SA fish are bred in SE Asia. Many fish are also bred in Europe, and you in the UK would have better access to those than we in NA.
Many species are still only wild-caught. Personally I will always acquire wild fish if at all possible, for a couple of reasons. They are usually better colour and condition, and they are often (usually) hardier and thus less likely to come down with various health problems. Of course, with my ideal soft acidic water, I am in the enviable position of being able to do this with no water issues. In fact, it is commercially-raised fish that are somewhat adapted to slightly harder water than give me more trouble.
Most SA countries now have fairly strict laws governing collection and exportation of fish. They can be caught only at certain times (after the spawning/fry season). The IUCN (International Union for Conservation of Nature has a red list of species at risk, etc. Most SA countries comply. Asia is a bit different story I gather. But as noted in the prior post, changes to the landscape (damming of rivers, etc) has done far more damage to fish stocks than aquarium collectors.
