Whatever you do though dont go to (do go to see how bad it is) the Pond shop just down the road from walskoken aquatics
Lol,It's not just me that thinks that then!
My other half went the other day as I'd bust the heater for my Betta tank and didn't think Walsoken was open on Sunday.
He had a browse round the fish section as you do,and they had several tanks with whitespot and/or corpses in,and a tank with what he thought were pink kissing gouramies all flopped on the bottom of the tank dying or already dead.He took a pic on his phone he was so shocked,but it wasn't very clear.I bet there were at least 8 or 9 in there though.
I don't go there anymore.It's too upsetting.
I know I should say something but they aren't the friendliest people either...maybe an anonymous letter to an animal welfare organisation is in order.
