Fish getting worse after treatment

[Dave 54]

Gemma, I'm not an expert, but I think your fish ( shubunkin ) has a bacterial infection / ulcer. You are fortunate to have it in a smaller container, as it's easier to treat and monitor. I believe you said you were using Melafix?

I've seen Baytril injections, recommended for bad infections, but I don't know enough to comment. Perhaps @Dave 54 , or @Meyer Jordan , would take a look and make a recommendation.

BTW, glad you figured out the photo uploading

Tula you are indeed correct that baytril can be used as an injectable anti-biotic but it isnt as simple as just injecting your fish like that first off we have the IM injection or Intra Muscular injection which can be done in a number in a number of locations however two of them do present problems when injecting , these are in the dorsal muscle , which is locatedjust belowthe front rayof the dorsal fin and the caudal muscle which is located between the anal fin and the caudal fin just below the lateral lineto inject in these two positions you need to insert underneath however another location and the one that I prefare is in the pectoral muscle .
The fish should be sedated and then should be laid on a wet towel
The other way of injecting your fish would be IP injection or Intra-peritoneal injection which involves injecting into the peritoneal spaceor the body cavity located behind the pelvic fins.
However with this form of injection there is an added risk because should the location of the injection sight be slightly wrong both serious and potential fatal damage to the internal organs and should only be undertaken by your vet or a fish health specialist trained in giving the injection.
Injectable baytril :-

I hope this helps but please remember it requires training to give both forms of injection

From my experience injecting fish i prefer to inject underneath of fish on the side on anal fin. I seemed to have most success for me doing the injections on that spot. I've tried other spots and only one of my koi i can be easily inject in dorsal muscle: on the side of dorsal fin: i have huge over 30'' koi and it's so big and heavy that it's hard to take her out and sedate her. So when i had to inject her due to bacterial infection, i just caught her in big net, and after she calms down just quickly injected her in the back without taking her out of the pond. All 5 injection went pretty quick and easy with her that way. She's so big that she can't really move quickly and she barely put up any fight without sedation plus the injection site didn't even leave any mark at all. However all others smaller fish (about 24'' and less) that i tried to inject in that spot it would always leave bad mark that would eventually heal, but it took long time, and since it's on the back you'll be looking at this mark for a long time. i've tried a couple of times to inject to pectoral fin muscle, but didn't like it, as fish would loose use of that fin for a while and look like that fin was paralyzed. the use of pectoral fin would eventually come back but it would take a while. when i inject next to anal fin it's much more successful. It still could be a mark from the injection but it's underneath the fish so you won't see it and would heal eventually. I just individual preference and i'm sure everyone has different preference of doing the injections. I also noticed that different fish react differently on sedation, as most fish are not hard to inject or do other manipulations after you sedate it, but i have one Kujaku koi that it so hard to deal with: no matter how long i'd keep him in the sedation solution he'd roll over and look sedated but once you take him out for injection he still fight like crazy in 85% of times i had to inject him witch makes it so much harder to deal with him. I've tried to increase the sedative dose, but didn't really make much difference. I'm afraid to put too much more then recommended not to make any permanent damage. So i definitely have one hard fighting koi in my pond.
