I went in today and they had some gorgeous new chocolate orandas in. Oh I wish I had space! *sigh* they may be dirty but I still love them 
It would seem like the more sensible way of doing it. Maybe you should talk to the manager/owner about your concern
I would love to...what would I say? I will think about it and try find a sensible way to do it. I doubt they will listen though. They probably think I don't know as much as I do as they have had no input into my goldfish education (that's all because of AC...thanks!) so they still think I'm an idiot who will put six into a 10G. They are actually all fishkeepers themselves (I've seen their tanks, which are all beautiful) - it's just fish that they don't care about that they are happy to mistreat.
Lupin, it's pond types, fancies, everything coldwater in this one. They also have something I've never seen before called Tench which are in the same condition. It's so wrong.
If they're truly dedicated as fish keepers/ store owners, they will take the time out to hear what you have to say. Your experience in the fish keeping world shouldn't matter to them. If you are concerned, just approach them and ask why the tanks are overcrowded. If they don't listen or don't care, stop going there. If they don't respect you, they will probably never respect the poor fish.
