I found my peacock cichlid stuck in a rock. I freed him but he has a big gash in his head and is swimming irraticly and even upside down. I took him out of tank and put him in a cycled 10 gallon half full with some Melafix and salt . Now he is just kinda floating in there upside down. He will swim a little. Please tell me he isnt ganna die and I did the right thing.
