my sen (got about 37 weeks ago when she was about 3 inches) has in the last week or so had red back fins- its been some time so i expect that has something to do with that? im getting my water tested and doing a tank cleaning on monday and plan on doing it more on schedule, but could anyone tell me what this is, how to get rid of it, and how to prevent it from happening once more? sorry about this- its the first fish ive kept and im gonna be crushed if something happens to her
