well the matted file fish didn't make it. I drip acclimated him and kept the water constant temp during the process. Just never was active much. Not sure what to expect from them but this one wasn't a strong swimmer, got blown around in the tank a bit when he did venture out. I don't have crazy flow either like a lot of you guys so I'm guessing he wasn't well when I got him. It's the super frustrating part about supporting local business. Pay more, and no warranty. I really wish they would offer an added warranty option or something. I'm probably done buying fish from local stores for a while until they do something better. less money and 2 week warranty... done.
anyways, gonna try some peppermints and see how it goes. I'll update on whether they get eaten or do the eating!
