Hello everyone. I've decided to post this hopping that maybe someone would see it and would have some ideas to what it could be with my koi.
I have 3 out of my 18 koi in my pond that have problems since last year. The most problematic one is the gold koi that is seeing in first 2 photos. I'm not new to pond keeping and had ponds for many years and saw many deceases from parasites, ulcers to dropsy. This gold koi doesn't come to a category of anything i've ever seen. Start from the beginning: I got this koi in June 2016 and it was around 8''. It was a big eater and grew up very fast but remained regular nice shape until end of winter of 2019. Sometimes last year in 2019 at the end of February I noticed that it started to be quite fat, round in shape. It otherwise acted normal and didn't show any kinds of sickness. So i was thinking maybe it's pregnant and will lay eggs in the summer and become normal. But it never happened and it stayed fat and round all year. So I thought maybe it became this shape and will stay like that. It look weird as i've never seeing fish this fat, but since it didn't act sick and always had good appetite I didn't do anything. I wouldn't even know what to do anyway. But recently I've started to notice that it slowly started to get even fatter. and now till the point that the scales are stated to be raised and started to look like dropsy fish. It's still doesn't act sick and swims around, eats etc. But at this point I see that it must be something wrong. I'm now sure what I could do. I've had fish with dropsy before and they always showed sickness before they blow up and would never would live that long, only would make it maybe a week or 2, but this one has been fat like this for 1.5 years. But since it started to blow up more now i really worry about this fish and not sure what i should do. I've recently treated the pond with anti-parasite Broad Spectrum Disease Treatment, did 3 treatments, and currently added praziquantel to the pond a few days ago. I do this precautionary treatments every spring. I was thinking that maybe this koi has some kind of intestinal parasites and possibly Prazi could take care of it. So far it's been 3 days since i ended Prazi but for now no changes. I'm not sure if I should try the antibiotic injections, a bit afraid that the water is still not very warm and koi's immune didn't developed like it's in the summer and it maybe it would stress the fish more by taking it out and injecting it. I can also try to isolate it in the tab and put medications, but still not sure what would be the best approach. If anyone ever seeing anything like this and know what would be the best for this koi, your advice would be greatly appreciated. the fist 2 photos is of the koi the way it looks now, and the last 2 is the way it look before 2019.
The other 2 koi i'd like to ask are on the photo #2 and 3. One of them: photo #2 is the platinum koi (next to gold koi) that also last winter became very crooked, his spine looks like it has scoliosis. He just became this way all of the sudden last winter of 2019. He doesn't look or act sick but i was curious if anything could be done to correct it, or it'll be staying this way forever? And the 3rd fish i owned since 2012 and suddenly also last year it started to grow some kind of tumors in 2 places on its side as seeing on photo #3. It's started to grow over a year ago and noticeably getting bigger. I'm wondering if anyone had anything like this and what could be done with it? I once had a fish that grow tumors on it's fins and tale. I sedated it and cut tumors out, the koi was fine after procedure. It was easier since only fins and tale were involved. I could probably try to cut them out in this koi but in this case it looks like it's kinda big and it's on the body not on the fins and I'm a bit afraid if i do cut it out the wound would be too big on his body and may not heal. So if anyone has any experience and/or ideas about any of this 3 koi i described any advice would be greatly appreciated. Th rest of the koi are fine. BTW I know that some may be asking later: all the water parameters are normal. No ammonia or nitrites present PH pretty stable around 8.5. So whatever caused it it's not water parameters.
