John88c Posted June 30 Share Posted June 30 I have been is a little tough spot i had my oscar in my 125 gallon tank with a tri-mac and have been away for past months checking in on them every week while i have been in the process of moving. I finally got to the point where i got rid of the tri- mac and moved my tank and oscar to my new place and noticed this one spot. The tri- mac has been picking on the oscar im afraid it might be Hole in Head 1 Link to comment Share on other sites More sharing options...

But could it also be head and lateral line erosion. Or hole in the head? Usually caused by increased organics and the hexamita parasite. @Colu Link to comment Share on other sites More sharing options...
Tony s Posted June 30 Share Posted June 30 Assuming that to be true, here’s coops read on that https://www.aquariumcoop.com/blogs/aquarium/hole-in-the-head That also attributes it to water quality, stress, and poor diet. As well as several different infections agents that step in to erode the tissue. first thing that I would do would be to clear up any excess organics in the water. Note, this does not mean your parameter numbers. But any extra bits of gunk floating around. Trust me, not throwing shade here. Lord knows I could use the same advice. Parameters can be fine while the tank is still a mess. Then switch to a high grade cichlid pellet to improve the diet. Ones from sera, extreme, north fin should help. Or a combination of all three. Then third, I’d watch the trimac very carefully. If it’s causing a lot of stress, it may need to be in a different tank. 1 Link to comment Share on other sites More sharing options...

The tri- mac has been picking on the oscar im afraid it might be Hole in Head That doesn't look like hole in the head I think that's an injury caused by the tri-mac cichlid I would increase water changes to lower the bacterial count add a small amount of aquarium salt 1 table spoon for 10 gallons that will aid Gill function and add essential electrolytes and monitor if you notice any change give us an update 2 Link to comment Share on other sites More sharing options...
Tony s Posted June 30 Share Posted June 30 Still leaves you the problem of what to do with your fish. Somebody has to go to a different tank for the long term health of the oscar. Link to comment Share on other sites More sharing options...
