Small lump/growth on Perc Clown

[Weapon_Master]

Help!!!!

I've had 3 fishes in total departing me one by one in the past 4 days. Now I am only left with a pair of True Perc Clown. I do not know the cause and only noted that it is possible bacteria infection on the mouth. All fishes that died had open mouth.

I just noticed a small lump/growth on the underside of the female perc clown. Both clowns are still feeding as of tonite.

I have been using Seachem Garlic guard for their every meal since day 1. The 2 Perc clowns have been in the tank for 3-4 weeks.

My Tank parameters now are

Salinity: 1.023

No2: 0 (Was 0.1 two days ago)

No3:0.1

PH 8.2

KH:10

What should I do? Any effective way to cure this? What disease is this?Thanks alot. Really desperate now. Dont want to lose my last 2 fishes.

Anyone can help before it is too late ? Still swimming and eating but really worried . The other 3 fishes have died after 1 day of not feeding.

Very very desperate to save its life !

BTW I just did a 30% water change 20mins ago. Hopefully it will help to ease abit.

Any expert can help? Its still feeding as of this morning but the lump is still there.

What could this be?

BTW it is a small lump considering it is on the underside of its mouth.

Hi, my three Perc Clown also got the same illness. Sometime it's the water conditions/perimeters not rite. U are rite to do a partial water change and continue to give treatments. Are there any HC/SC or other fishes that died or is dying? Might help by removing them.

fish dead with open mouth doesnt means they have mouth illness. humans do die with open mouth too and doesnt means they died of mouth illness too. mouth open is due to pain agony felt when the fish is dying. maybe its ulcer or aids, LOL

Hehe. Found out that it should be ulcer and am currently dosing Waterlife Myxazin for medication.

Both fishes are still feeding as of this morning. Hopefully this ordeal will be over soon.

Thanks for your advice.

I have been dozing Myxazin in my tank (recommended dosage) for my True Perc that is down with Ulcer for the last 60 hours. Protein Skimmer has been off throughout this period.

The situation seems to be improving but abeit slowly. Can anyone advise how long this healing process will likely take?

Do I continue to dose Myxazin? When should I be stopping? The instructions on the medication is to stop only 2 days after the ulcer disappear.

Should I be performing any water change or should I be waiting until after the medication stops?
