Thankfully there is only 3 petstores that sell fish and 2 of them are the mom and pop shops.They keep there tanks clean all the time aswell as when a fish is sick they treat the tank and refuse to sell them.The people who work at these store actualy keep fish and have for many years so they will always give you advise even when it not something you want to hear.The other petsore though is the exact opposite know absoluty nothing about any animals in general.I rufuse to go in there now.A few months back I went in and they had a big bull bristenose pleco(6in).So I asked if i could get that pleco and she had know idea what I was talking about.So I said "the big black one with the sucker mouth and the and the little bristles on his nose"So while I was waiting the 10min to catch the fish I went to go look around.Then I came back on she had a little panda cory in the bag.So I just laughed in her face and I ended up catching the fish myself.Then someone brought a senagal bichir in but the guy who brought it in didnt know what it was.So they had about 3 employees standing around trying to figure it out then I took one look and told them what it was but they refuse to listen to me. So after a bunch of arguing they decided that it was a tiretrack eel I called them all fools and havent been back since.
