I've dosed octozin for 2 days (third and final day today) and hopefully this will kill any parasites that may have caused this wound. I've also dropped the quarantine tank temperature to 20C to slow down the bacteria in the wound. Will let you know how it goes...
Thanks for that, really appreciate it! Unfortunately Metronidazole is very difficult to get hold of. The only way I could get it is through a vet, and I'd have to get a consultation first. I work 7 days on/7days off and I won't be off work now until next Thursday. By then if the treatment hasn't worked the infection will be much further on and treatment is expensive (?80 for metronidazole, plus the vet's fees). Octozin is the closest I can get (I think it's di-metronidazole and salt basically anyway).
I'm afraid it's a mixed bag - some bad news, some good:
The hole now looks bigger (wider) on both sides. It's quite shocking to be honest, however it isn't as raw (pink) as it was and the swelling around the middle of the fish has gone.
Behavior has also improved with the fish hiding and reacting better. Previously if I moved a rock there was no sense of urgency to get out of the way which made catching very easy. Tonight I moved a rock and the fish shot out and under another rock.
I also fed a spirulina tab to gauge interest in food and response was very good, I just need to take care not to overfeed. I think I'm going to continue with the Octozin anti-parasite meds and keep fingers crossed.
I have a question then. I'm fairly sure that the fish has a parasite. Should I dose the main display tank with meds too?
Sadly the fish died last night, it was riddled with holes :(
But with death comes life, I found 7 or 8 eggs in a crack between some slates and an angry-looking female Julidochromis Ornatus guarding them. After a while I noticed some tiny babies (presumably a previous brood) clinging upside down to the rocks around the same area. These are fish I haven't kept until this year so as ever I'm pleased to see something new occuring in my tank. They will be transferred to a fry tank once the second batch of eggs has hatched. I will probably also move the pair with them as apparently this helps to maintain the bond between them and they seem like great parents too.
but good news about the julies though I wish you luck catching those tiny fry - I spent DAYS the other week catching a few multi fry which didn't have the sense to dart into shells when I was moving them all to a new tank
