So I have read that pet stores/fish stores feed fish at night because transport on full bellies can cause extra stress. No more than two days later I'm at a local big box and an employee is blasting bloodworms into a saltwater tank to catch some fish (pretty white and black stripped ones). My fiancé asks him why he is feeding them, he replies that it is the only way to catch them. The tank did appear to have an awkward hood/entry point and there were a lot of hiding places in the rock in the tank. Still unsure how I feel about the whole situation, idk if he was just not willing to catch them with skill or if the store really just set Him up for failure with a bad setup or false info maybe.....
I can't recall the source of this comment. I just remember reading it. I can see how a nicely fed fish would be happy. But also I could see transport on a full belly being stressful, I don't like to do much when I'm full
The online vendors who ship fish wont feed them before shipping so the chance of the fish pooping is reduced. Poop=ammonia. Ammonia in a small bag with no filtration adds more stress to an already stressed fish. Not quite the same as you picking up a fish at your lfs, and driving it home.
Yeah... Crediting him for the fish you sold him is totally reasonable, but all his fish that you didn't sell him? Nice try.
It's totally common for fish to be carriers where they carry a parasite and are immune to it and show no signs themselves but can pass it on to a tank. Even the best care at a LFS won't catch everything. It's up to the buyer to do a round of QT with parasite treatments prior to adding it to a tank. If you don't do that, you're responsible for the risks to your tank.
