Hello, I have two ACF in a 20 gallon long tank. They have lived together there whole 10+ year life. Just this week i noticed that the female seems to have lost the tip of one of her front fingers. I have no idea how it happened, but none the less it did. Is there anything i should do for it? any tips are appreciated! She is still swimming, eating, acting normal. just missing a part of a finger.


thanks!
