Hi Laomedon, yes I do live on the East Coast of Africa in the city of Durban which is right next to the Indian Ocean. Some of the more popular dive spots are places like Protea Banks where Aliwal shoal is situated. Famous for diving with Ragged Tooth Sharks. Slightly further North is Sodwana which also has some awesome reefs. Some of the fish indeginous to our Coastline are, Powder Blue Tangs, Convict Tangs, Pajama Tangs, Chocklate Tangs, Variety of wrasse, Angels and Butterflies. Anthias (The psuedoanthias squampinis in my tank are locally caught). Every couple of seasons the guy's get really lucky and have caught the infamous Zebrosoma Gemmatum of our shores.
A permit allows you to collect specimans for your own tank BUT the collection of inverts is prohibited.
It's pretty much grey area as far as what classifies as an "Invert" and one of those blanket legislations put in place to protect against the plundering of abalone, crayfish, mussel etc. However things like hermit crabs, urchins, brittle stars etc are readlily picked up in rock pools and along beaches.
Guy's have also been known to collect corals from shallow rock pools and man made reefs. Not that there's too much wildly exciting. We not quite in the tropical zone so the water temps average around 22-24 Deg Celcius in summer and in the 18's in winter. Further North towards Mozambique On our northern coastal border) it starts to get really cool and particularly in the Bazzaruto Archipelgo there are some awesome reefs but again here strict legislation prevents the collection of coral.
