I would like to see some captive bred inverts like urchins and snails if they arent already available. In terms of fish, maybe a Fox Face Rabbitfish would be nice.
I am making it a mission to only purchase tank bred fish for my aquarium. I have 2 tanks, one is an African Cichlid tank, well nearly everything is tank bred there, the other a reef. It is still quite hard to get tank bred fish for my reef aquarium, so I have a handful of fish that I could get tank bred, but will likely concentrate on the corals until more fish become available.
I was trying to get a pair of Yellow, and a pair of Regal tangs to go in together, but all the shops have sold out of yellows which are getting so expensive now anyway that it is getting unaffordable, although purple tangs would do as a substitute, and the Regals are all wild caught, so an increase in supply would be handy.
I want to reduce the impact of my aquarium on the reefs, and encourage the breeders, so only tank bred fish, and aqua cultured corals will be purchased. I just have to trust the shop that they are, cant see any way of proving it.
