He lost some fin. He's swimming and eating and seems fine right now. I'm just worried about infection. Should I add aquarium salt to his water? Is sea salt the same thing. I already have that on hand and can add that right away. What is the proper ratio and how do you add it. Pre-dissolve it in warmed water or will it dissolve if I put it in the water jug and give a good shake? Sorry for such newby questions.
I've only had him for a few weeks. I feel so bad for him. He fell down into the drain in my kitchen sink. I was afraid I wasn't going to be able to recover him.
Thanks for any info you can give.
