    Looks like a blue kurper (Oreochromis mossambicus)?

    Did you collect it yourself?

    @ancistrus and salmonAfrica , I believe that is correct. My son came home from a dam with some fry in a lunch box that he had proudly captured. I put them in a tank. I then saved another 8 when a friend was moving and had to fill their pond. Got 15 hand size guys in that tank.

    Looks like the start of a fungs or fin rot. Not 100% sure - I am sure the other members here would be able to advise better. Maybe start with a general tonic\medication as you mentioned its in a quarantine tank.

    I personally also like to add abit of general medication to the main tank just as a precaution as well! and monitor closely to see no other fish get the symptoms.

    @AmithS. Thanks, I haven't noticed this on any other fish? Doesn't look like fin rot and fins etc are looking health? Almost looks like some sort of parasite but could be a fungus . Strange thing is when I got home today it seems to have vanished? And I have only treated with salt and a dewormer. Fish is still very nervous so don't want to stress him out too much by prodding around.

    Sounds good. Try and do a daily water change to help the recovery along and remove any potential disease from the quarantine tank.

    Love tilapia - one of my favorite fresh water fish for the plate. The other is giant gourami and also the well loved Pangasius available on your not so OB menu ;-)

    Hi All, any else have any ideas on this. I did a salt treatment and the affected area cleared up in a couple hours +- 10, there was no visible damage etc to the affected area that I could see , but the next morning it looked to be returning? I am now treating for fungus etc... I have also noticed that his eyes are bulging a bit, is this bacteria then? ( He has always been a little bug eyed so I'm not sure if I'm seeing things here)

    Could just be a little water quality issues, they are big and tilapia are messy. a Few small water changes should help with the fungus, also finish your treatment as per the instructions and it should clear up. I see there's some ammonia, maybe look at increasing your bio media as the filter isn't keeping up or not finished it's cycle yet.

    Maybe not relevant but how often do you replace your carbon and what brand do you use?

    Saw your nitrates is at 30-50ppm also. That's a little on the high side as well. You don't want to go over 20ppm for good fish health.

    I can't really make out from the pics but, it looks like that fish may have fin fractures.

    Just do a Google for "fish fin fractures" and let us know if it's the same thing on your fish.
