Adelaide Aquariums used to be a very well respected fish supplier in Australia, and perhaps, will be that way again. However, when I went to find the link for you, I found that the company appears to be going through some reorganization. Perhaps you might want to send them an email to get on their mailing list and find out when they will back to normal.
In the meanwhile, we do have a good number of Australian members, so I would suggest you post your question in the Tropical Chit Chat section. Members who specialize in other kinds of fish might see it there and post links to sites that also stock corys.
Another way to get new fish, and have a good time too, is to join a local aquarium society. Members auction and trade fish they have raised and have knowledge of all the nearby resources.
Good luck with the search for new corys. That's a big part of the fun of keeping them!
thanks for that, i used to kep heaps of fish but got out of it, i actually was a member on here a while back but i forgot my username, all i know it was rainbow fish sometihng lol but yea, i decied to get a couple of corys so now i want MORE
Adelaide Aquariums is changing, and it doesnt have a store front anymore. It wont be open for business to the general public to the best of my knowledge. He said he would be back though, so he isnt getting out, just changing a few things, doing something else so ive heard.
It depends on which state your in as to whether I can really help you that much. If your in SA, give us a PM or reply here!!
The best chance I get of getting rare fish, is becoming known around the LFS's, and letting them know your after something. Either give them your number and what your after, or order them in!
