Hey. We have a pond outside with Koi and Goldfishes, I dont really know the species tho. Anyway, when they got small babys last fall, we took them inside in a tank to let them grow and we moved them out last week.
When my brothers was going to catch the last one he hit the back fin of it, and he has been looking very bad for the past week.. I'm no experienced fish owner, but when they decided to see if it lived or not I thought I would take care of it instead, and I have for the past week.
The first couple of days he was just lying in the bottom of the tank on his side, and he usually does that, except from some swimming that lasts for a couple of seconds..
First I thought I'd just leave him and have him recover, I usually feed him having he swimming inside my hand in the top of the tank, but it is hard as he struggles with holding balance etc. The main problem is feeding him, cause it takes a long time and how am I to know if he is stomach is filled or not.
It looks like his back fin is broken or something, because when he swims he "shakes" his body, and it kind of looks like his tail isnt moving as it should. It's almost like there is very little power in the fin. I googled it a little bit, and I heard that black spots could be a sign of injury or disease, and he got those but they have been disappearing and are
almost completely gone now.
Hope you guys have some tips..I'm curious if he is paralyzed or if he will recover..
Here are some pictures, I put him in a small bowl to see if he could eat some on his own, and he is doing so the best he can. And then there is a pic of the main tank he usually is in.
In the first picture you can see how he is lying on one side.. The bowl-water is only dirty because of some "powder" food for baby fishes.
