Hi Everybody,

I have a 220L american cichlid community tank and one severum has a fin which seems to be swollen at the joint only on one side, otherwise he seems fine. Any idea what this can be? Is it columnaris maybe?

Don’t think it’s columnaris but never really know. Add some triple sulfa and increase ur water changes to weekly.

Thank you for your feedback kno4te, I will see what medication I can find similar to API Triple Sulfa because we don't have that brand locally but I will increase my water changes to weekly and see how it goes.
