HLLE? Two spot Bristletooth

[ChathamONCraig.]

Is this HLLE?
Came on fast. Fish arrived into my tank five days ago. Was doing fine, but now I see this.
Tank is 90g/35g sump, running for 8 months. Two T5 lights and a power head.
Water parameters test fine and all within range.
Checked for stray voltages, none.
Feeding mysis, brine, emerald entre, and small bits of nori.

Fish was actively buzzing around, picking away at the GHA looking fine until I spotted this today.
It isn't actively swimming around now, just hanging out in one spot.

Tank mates are Blue Tang, another two spot bristletooth, orchid dottyback, two oscillaris, four Banggai, diamond watchman gobi, Halloween urchin.
All of them get along well.

I'm making up another 20 gallon sw for a vaccum and change

That’s not HLLE. Looks like an injury, then a secondary bacterial infection.

It may or may not get better on its own. However, to treat this, you would need to move the fish to a hospital tank and treat with a broad spectrum, gram negative antibiotic like neomycin.

Ok, thank you Jay.

I'll have to get one set up. My pharmacist is quite good at helping me out. I will go to him tomorrow for some neomycin.
Any hints on dosage? The fish is just shy of two inches.

I use 25 mg/l every three days for three treatments. To calculate this, you multiple the actual gallon capacity of the tank by 25 and then divide by 264. So, for ten gallons, that works out to be one gram.

Injury, most likely or a sting. My WT Bristletooth gets injured all the time but usually does not look like that. What inverts do you have? Just the Urchin? You may have a problem with one of the other Tankmates.

The other inverts are snails. The only thing that stings in there is a Frogspawn

The injury thought is beginning to make sense to me now. The fish is very fast, zipping around and through the rockwork. Perhaps he (?) whacked his head dashing through the landscape.

It seems to be back to normal, speeding around and eating as the day has progressed.
I will still like to treat for infection as suggested by Jay Hemdal above.

The frogspawn could have started this. Fish are well adapted for living around sharp corals on the reef, so it is unlikely that it ran into something by accident.

Signs of infection are if the lesion is growing larger over time, or increased depth to the lesion.

Right - there you go. It can also be a non-sting. either way - looks like a scrape/stin
