Hi everyone! I need help identifying what's going on with my little guy(?)
All my fish have lived together for well over a month, except some new ember tetra, which I've had for 3 weeks. They have all been together in this new tank for 2 weeks now. And today I see these white bumps on my dwarf pea puffer. My first thought is ich, but I've only encountered it once about 8 yrs ago, and only saw it after the fish had died (it was on a shy sucker's belly). I've never seen ich look like bumps, only spots, I thought it was sand they're so big. And this puffer is the only one who has it.
Does this seem like a case of ich, or something else?
