Hey guys,

While doing tank maintenance today, I noticed my German Blue Ram has about 4-5 white/beige/pink protruding spots on its head that literally look like pimples. The most concerning one is a big bump on its forehead with a pimple on top—it kind of looks like really bad acne.

Looking closer, I also noticed a tiny red vein on one side of its head. Not sure if that means anything, but I figured I’d mention it since I’m inspecting everything super closely now.

On top of that, one of my dwarf rainbowfish has a white, flat, fungus-like patch on its body—almost like a bacterial infection. There’s also a white streak along its body, and overall, it looks kind of rough. I couldn't get a nice pic since it was swimming at the back. Like I said, it still swims actively but stays near the back of the tank instead of with the rest of the fish. It’s been like this way for about a month. I think that its bacterial, so I’ve just been doing larger water changes to see if anything improves.
I used to have a school of 12 about a year ago, but they all gradually ended up swimming to the surface and dying in the same way. Now I have 2, including the 1 I'm talking about that is affected. I asked my LFS about it, and they mentioned that dwarf rainbows aren’t as hardy as they used to be.

I’ve uploaded photos of both fish. Based on what I’m seeing online, I think my German Blue Ram might have early-stage Hexamita/Hole-in-the-Head disease, while the dwarf rainbow seems to have a fungal infection. I do have Metronidazole medication on hand, but I want to be sure before treating the GBR and entire tank with meds.

I wanted to mention that I added more fish to the tank recently but I quarantined them with meds as a precaution for a little over month before I did. Ive heard that hexamita takes a very long time to show symptoms, just to let you guys know I forgot when I got the GBR, but it's been at least 5 months.

Let me know what you guys think! I appreciate any help in figuring this stuff out.

I never seen that before, and I am wondering if it is the start of Hole in the head. I would suspect parasitic. Hopefully somebody here can jump in and know what this is.

If it is the start of hole in the head, any medication containing metronidazole like API General Cure or Seachem Metroplex would treat that.

Yeah that's the start of hexamita, the sensory pores swell up and get a white center at first before they rupture.

Definitely treat with metronidazole for this

You can see here how it progressed on my elderly Bolivian ram:
