About two months ago, my CT got into a fight with my largest Rosey Red, Nana. The results were that she lost every fin and he lost every single ray extension that he had. Since then i have managed to actually save Nana, but Red has only grown back 3 extensions. After a terrible swing with Swim Bladder Disorder, my fault, i began to notice a darkening around the edges of his fins. Naturally i freaked out, figuring that i bought the most sickily fish on Earth. Closer inspection revealed that is was a trick of the light. But his fins still refuse to grow back. I am a poor high school student with very little money. I use Oak leaves in the place of IAL. Although he has been cured of his Swim Bladder, he still has trouble swimming every now and then. So i put about 1 teaspoon of NONiodized salt into his tank once a week when i do a water change. His Ph is at 7.7 dispite my only puting pure water with salt into the tank. He is perfectly happy, regularly building bubble nests, dancing for me, etc. But can anyone help me to heal his fins? Remember, i am poor, little acess to anything.
