So this is my Nerite, Zero. He's lived in this tank with a betta and cherry shrimp for about 6 months. Parameters are all good, there's cuttlebone in there for him and the shrimp, it's heavily planted, 78 degrees, with algae for him to eat as well as Hikari bottom feeder pellets and algae wafers that go in.
As of today, he has what looks to me like an injury. Is this my betta fish finally getting to him or is it something else? Do you think he'll be okay, is there anything I can do to help him?
