Hi everyone - is anyone still here?

I've recently started keeping freshwater fish. It would be great if we could get together a community here when we can swap/ sell fish, fry, plants and accessories. The shops won't take in unwanted fish, so we need to help each other out. If I buy a fish who turns out to be aggressive towards my others and the shops won't take it back, and I have no space for another tank to keep the fish in isolation, what am I supposed to do?

I'm having trouble finding a good place to buy fish on the Island, I have had bad experiences with most of the shops. Which shop do you recommend? Is there any company which would courier fish to the Isle of Man?
