Does anyone know what this bump under Ziva's nostril is? It reminds me of a pimple. Her "buddy" has been nipping at her sometimes....I have no idea why. Her tail has some rips, which I think her friend did, too. She is a comet and he will give her long tail a nip. They've been together for 5 yrs. As a side note- my tank has been going through a cycle since I upgraded. I thought my fishless cycle was finished, but when I added the fish, ammonia went up. 45 gal, Amm .5-1, NO2 .25-.50. pH 6.2 (always low). I'm wondering about adding meds, but I hate to just start throwing stuff in there.
Thanks, I hope someone can help me!
