Hello all. I've had a betta sorority establishe for about 6 months now. My girls are all happy and healthy, and have live in tank mates of 2 loaches, a pleco, and 4 cories. Everyone is happy, and big old cheesy personalities. I have found though, that one of my girls, Wenatchee, has been so stressed lately. I've watched continuously as I'm on bed rest after surgery, and there's no bullying. I have a 36 gallon bowfront. Filtered with a Fluval 3 on a Very very low current. It's well planted, and there's plenty of hiding space. My temp is kept at 78 degrees and I have 3 crowntails, and 3 veil tails. Wenatchee stress lines just won't go away. I've tried water changes, rearranging of the tank, stress additives, and cupping. She's not ill. My tank has a clean bill of health! Thanks you guys!
