Hi, I have a 20 gallon tank, today one of my female betta's (no males in the tank) got stuck in a plastic cliff hole, she was unable to move either way and I had to pick it up and carefully help push her foward (as not to damage her gills by pushing backwards). She seems fine, other than a loss of scales on her dorsol side and kinda red at spots. Since our tank is recovering from Ich, I decided to put her in a isolation tank. Is this the right move, is there any medicine I should get her or anything else I should do? Help!, Thanks.
