Sorry, last thing... I noticed their Betta display had the water outlets running at full pelt, resulting in the fish sitting clamped at the bottom of their tanks. I had a nice chat with the manageress and two minutes later the fish had a mere drip-drip into their tanks and a full dose of blackwater extract circulating amongst them. 10 mins later, all the fish were merrily prancing around and looking very much happier with themselves. Nice to find a LFS happy to listen to advice and take it on board! They've promised to never let the taps go on 'fast' again and to make sure they get regular black-water or Betta Spa top ups.
