Backyard Aquaponics
A place to discuss aquaponics

Ahhh! Two of my tilapia look like they have a little ich and a redish jaw line. They are were exposed to a spike in poor quality water for a short time, now the water is sitting at about .25 ppm of both ammonia and nitrate.

I added salt and extra air and they seem better.
Please tell me i don't have to kill my good guys in the tank and bleach the system!

leave them be for a bit, hold off on feed.. the coloration could be a sign of sexual maturity, what makes you think they have ich?

It might not be ick. I've never seen it before so i wouldn't know. I'm just guessing based on photos. It looks more like missing scales or patches then bubbles. It's hard to tell from the hoto because my glass is growing good green fish food on it, but that white patch is on the fish, not the glass.
Might be bites from the other fish. Tilapia are not friendly! Ow.. They beat each other up all day. I tell the kids they are playing tag!

put a couple flower clay flower pots in your tank, facing away from each other.. male tilapia want their own territory
looks like marks from aggressive fish, not ich

Doesn't look like ich to me either. You usually see it first on the fins and just like every description of ich says - it looks just like salt crystals on their fins. I've used freshwater baths on saltwater fish and saltwater baths on freshwater fish and that helps also raised the water temp to 88 degrees F and it will fall off.

I have some fish in a 55 gallon tank just to view better and I have some pvc piping in there they like to hang out in but they get crazy and swim like mad and bump them selves up the markings on your fish look similar to the ones mine get...they should heal up. is there anything in the tank they could run into like the pvc or some rocks?
