We are an amalgamation of many different hobbyists here. There are dwarf shrimp, planted tanks, cichlid, goldfish/koi, pleco, catfish, betta, oddball, community, marine (FOWLR), and reef enthusiasts to name a few.
For Africans i would contact sholtztom on this forum. He breed africans and I believe is still a sponsor at africancichlids.ca. Good luck on the hunt.
Animal House will be your most complete petstore for stuff. Oly's Pets on Yale rd has the cheapest fish food. As well, Fraser Valley Tropicals (Kirk) is a sponsor here and he is based out of Cultus Lake. Check out his profile and website in the sponsor forum
