Yep, avoid Fish People for anything living - it's ok for food and supplies and some of the staff are very nice, but fish wise, they're utter crap. I lost £75 worth of fish from them within a week of getting them - my tanks are perfect stat wise, and the only fish that died were the ones from them. Must say - they did replace two of the plecs (value £40 ish max), but they just have crap suppliers. Avoid, avoid, avoid, I dont know how many times I can say it lol.
Edited to add - I also know of someone who bought some angels from them who were badly diseased with columnaris, and when they rang to warn the shop - they were told yes they knew, and they were being removed from sale - when she either rang in again or went in (cant remember) to update and get her refund (which I dont think she got either), and then on another occasion she found out they'd sold on the whole tank of fish knowing they had columnaris and were fluffy and sick.
That's why I wont buy fish from them again. I wish my hubby would listen, he still gets some now and again for his tank, but they cant even tempt me with the L nos they're now stocking. Honestly, I think the manager is a decent bloke, but some of his staff are nothing less than village idiots, and his wife - although I've personally not met her so dont know how true this is - is supposed to drive a hard bargain when it comes to deserved refunds.
