Midas Blenny injury or illness?

[JayM]

Noticed this spot behind his pectoral fin today. Everything is otherwise normal. Eating, swimming, etc. He’s been in the tank for a little over a month, and never any aggression that I’ve seen between him and any of his tank mates.

Haven’t tested water since last week, but ammonia was .1, nitrate 16, ph 7.8, phos .3, nitrite .1 temp bounces at 78°- 79°.

Coral sting? Abrasion? Or something more sinister?

Could be a simple abrasion, tough to see, can you tell if this looks like the skin is damaged, or is it more like something is erupting from underneath the skin?

I wish I could say for sure. He doesn’t sit still long enough to be 100% sure. If he was human, I’d say It sort of looks like a blood blister.

My first thought was hyperpigmentation of some sort, but it’s definitely a raised bump.

It doesn’t look like a coral sting. There are some internal infections like Icthyophonus that can cause eruptive pustules. Difficult to treat those, but some are self-limiting and can just heal up.

I’m uploading a video to YouTube in the off chance that it may help.

Fish swimming well. It looks a little thin.
Is it eating well? If so, what foods are you feeding?
For the pimple abrasion, ruby Rally pro will help in tank or in quarantine- seachem neoplex but keep an eye on it as suggested by Jay Unless it gets/develops into sore or redness

Eats like a pig. LRS reef frenzy in the evening and flakes at least twice a day, sometimes more. I feed pellets a few times a week as well.

I don't see anything immediately treatable here. The "skinny blenny" issue is something to watch for though:

Skinny Blenny issue

Skinny blennies: Midas blennies are much more difficult to maintain than their common presence in the pet trade would have you believe. They are very prone to starvation. It is unknown if this is due to not feeding them often enough, not feeding enough, feeding the wrong foods, or if internal...

It seems that whatever the cause, it’s getting better. It now appears to be just a discoloration. It’s no longer a bump.
