My new female betta is keeping her caudal fin clamped. Its only that fin. I thought at first that she might just be stressed but it's been days now and shes only unclamped it a tiny bit (or that could be my imagination). Now I'm worried. Is there anything I can do for her?
She is still in her cup that I bought her in but its floating in a heated 10g. temp is about 76. I change her water every other day.
Also I was planning on releasing all my girls into my new sorority tomorrow. Will she be okay to go in or should I wait until her fin unclamps?
