im still trying to convince her, it seems like it is harder than i thought lol. i just look up 75g tank price, and i think i could afford it if im saving for 2-4 months, the hardest part is to convince my wife to buy another tankWell between the pics you have I am confident its definitely a cichlid. Red terror or red devil something like that. I will warn I have seen something like that type of injury in some albino corry cats. For them it turned out to be a flesh eating bacteria I was unable to control. I had worked it's way under their scales and literally ate them alive. It was horrible!! Tried every thing I could to stop it. But it swept though about half my tank. That's as I was pulling fish with symptoms out and putting them all in QT. Seemed every time I looked back in the main tank I seen more. Also it transferred to another tank simply by a net careless set on top the uninfected tank. And the net dripped into that tank causing another contaminated tank. After it seems to run its course it did go away never to be seen in that tank again. But I tried about 4 meds and none stopped any fish from falling to it if infected. As soon as I seen your second pic it definitely made me shiver a little remembering that. There could be a ton of other reasons for the injury. I didn't happen to see any kind of decorations in the tank. So my first thought was some sort of bacterial infection. Considering the water quality. I know were I live I could probably come up with a 55 gal pretty cheap and pretty quickly if needed. Not sure your situation but if you thought that was possible for you, I would, and have lol. Good luck my friend with whichever you choose.
btw thank you very much, for all of you who replied here im really appreciated it !
