My Platy recently started showing these white bumps on her tail fin. She's not been eating much of anything the past few days. I have seen one of my guppies nip at her once in the past few days which I've never seen them do before.
Any thoughts on what this might be? I haven't introduced any new plants or fish within the past month. Parameters have been ok. The 20 gallon tank is a little on the busy side (5 platies, 5 guppies, 5 danios, handful of snails, 2 shrimp), but I'm generally on top of water changes (once a week). The danios are relatively new but have been in the tank for about 1 1/2 months now.
Thanks in advance for any help or advice!
