Would Someone Mind Checking My Stocking?

[Fintastic!]

Thanks guys. I do take everything on board and appreciaty your comments. I do feel bad about the fish being not as suited to the environment as I'd like, the only thing is if I return them they'll only end up in a similar situation in another home. I enquired about them being sub-tropical in the 4 petshops in my city (as lucky for me they're all reachable) and they all keep them at a higher temp and see no problem.
My point is I understand my conditions aren't ideal but they obviously don't see it as an issue so sadly they'll sell them on regardless.
As Soybean said, I wouldn't now buy the same stock give or take a few as I've learned so much here and I wouldn't buy anything without seeking advice but I'll do my best to see my fish thrive.
