So, I went to get some Neon Tetras for my betta today at Pet Valu. (Yes, at my pet valu they have pets, I don't know why but they do). When I went to get some, a guy who worked there told me some serious misinformation. This was worse than total bs this guy sounded absolutely clueless. Here some of the things that he said:
"Betta fish will instantly kill any other fish that comes in their tank including Neon Tetras. You cannot put any other fish in a betta tank."
"Neon Tetras need to be heated to 75-80 degrees, and that is terrible for your Betta fish."
"Even if you get some plants for Neon Tetras to hide in, that will do nothing. The betta fish will still swim in and eat the fish."
Obviously, I bought the fish anyway. The guy said that it was animal cruelty if I was just going to buy fish so other fish could kill them, and gave me a dirty look as I left the store. I told him "No offense, but I think you should research betta fish some more." He told me that he was a 'fish expert' and that he knew what he was talking about.
I feel sad for all the fish under his care.
