I have no idea if ANGFA WA is still running. You can google it and see if anything turns up. There is ANGFA National, which is based over east but there was an ANGFA branch in each state. The last I heard was meetings were being held every second month and the alternate months were normal Aquarium Society of WA meetings. I think the meetings were held at the Sandgate Street community hall in South Perth.
Just did some googling then and it looks like the Sandgate St community hall has been removed and a new building set up further up the road. However, the ANGFA website says the ANGFA WA meetings are now being held at the Manning Community Centre, 2 Conochie Crescent, Manning. Details at the following link.

You don't have to be an adult to join ANGFA, kids can join if they want to. I did write some articles for ANGFA. You don't want to keep rainbowfish unless you can get wild caught fish or fish that are free of Fish TB.

Back in the 80s and 90s everyone in the pet industry knew everyone else in the pet industry. At one of the shops where I worked, we didn't carry many African Rift Lake cichlids so when we had customers come in looking for them, we would send them to Vebas where Chris and Harry had a lot of Rift Lake cichlids. In return they used to send marine customers to us because they didn't carry marine fish at that time and we did. We did this with other shops too. If someone needed something or a particular fish, one of the staff would know who had what and if we didn't know, we would call around and see who has what and send the customer there. It was nice and most of the shop workers would visit each other at their shops on a regular basis and a lot of us went to the different fish club meetings and interacted there too.
When I was in ANGFA WA I used to visit a few shops every month before the meetings and make a list of the native fishes being sold at those shops. I didn't put down the prices, just a list of the species that were available at that particular time. I put the list in the ANGFA WA newsletter so members could see what was available. A lot of the shops liked this because they were getting free advertising and many used to donate items to the raffle table, which was also advertising for them. I don't know if this still occurs but when covid19 hit, people didn't go out much and they stopped having fish club meetings for a while. The shops might still donate items, I don't know because I haven't been to a meeting for years. I can't remember why I stopped going to fish club meetings, I think it was around the time I lost my fish to TB.
