so my clownfish disappeared after its partner jumped out of the tank a while back, more than 3-4 months ago. Probably at the beginning of this past summer. We’ll long story short I found it in the back area of the overflow where it jumped into a long time ago and when I turned off the pumps it came up and begged me to put it back into the tank. I haven’t seen this fish in at least 3 and a half months, and now it’s so skinny I can see bones and it’s not healthy. I just fed the tank and it ate a ton and is now residing in a little breeding box. What can I do to nurse this fish back to health, I feel horrible and should have checked the overflow a long time ago. I’m assuming it ate a small amount of food that came through the overflow after feedings. Please help!!
