I inherited a fish about a year ago, the poor thing had some serious stress during its life with its previous owner. It jumped out of the pond a number of times due to bad filtration and water conditions. Spent some time in a green swimming pool too, luckily HTH wasn't added for a few months prior....anyway I took him on and put him in my pond.
When I got him, he had the start of an ulcer on his back, just ahead of the dorsal fin between the head and the fin. The ulcer has not grown in size, the fish is 50cm, and the ulcer is 2-3cm, it has also not broken through the scales to reveal flesh. The scales are a bit raised though and there is some pinkness. Some weeks it looks like the ulcer is getting better, but every now and then it seems to "flare" up again.
The fish is active, eats well, doesn't jump, and is generally happy. Water parametres are perfect although the TA could be higher, its a bit low.
I don't like the idea of taking him out and applying medicine, so I want to ask if Garlic will sort him out or if there is a food with ulcer meds in it to feed him?
Thanks for your help
