My albino oscar is well peeling is the only way to describe it. uploading the pics but i did a 45% water change as soon as i noticed it he still eats the same just looks like hes peeling ive never seen this happen on my other red Oscar
my dads convict had this much worse and no body here was able to help me on what it was. i still dont know what it is but if you let it keep going it will start to dig into his flesh and you willl see red and white of blood and flesh that was wat my convict got i raised the temp, freshwater salt and i belive it was coppersafe that i added took a long time to fix but he is better ill get a pic of what he used to look like with it i cant find one but it started like that does his scales look almost like a clear cloudy white on the edges if so take action and take out anything sharp that he could scratch on and do more damage
and as for quarantine hes to large to move out of the 210 into anyof my other tanks and the fact the only other tank that could hold him is my 55 gallon and that has my breeder guppies for my turtles
