Hello,
Unfortunately, I think some of my fish are infected with mycobacterium, or Fish Tb. I would really appreciate any advice on what to do with the fish that show no signs of infection...
About six weeks ago one of my rainbow fish developed a red lesion/ulcer on its side. It has no other symptoms. Still eating, swimming as normal etc. I isolated him and he is still alive. Three other rainbow fish developed similar lesions on side. Same story, no other symptoms, still alive.
bout one week ago one albino coryadora suddenly developed red spots, fin rot and died suddenly. Twenty-four hours ago, one glass catfish developed a sudden curvature of the spine and is now swimming near the surface.
I had been treating for a bacterial infection with a fish bath every two days, containing Tetramedica “general tonic” containing ethacridine-lactate, acriflavin, methylene blue, 9-aminoacridine hydrochloride (plus I added some salt). It has had no effect on the lesions. Please note, I live in Thailand and this is the best medicine available. No fish antibiotics are sold here, and in most cases you are lucky to find anything apart from Malachite green!
I am sending the fish to the veterinary science department of the Bangkok university tomorrow to try and get a definite diagnosis (no regular vets here treat fish - only cats, dogs etc).
From what I have read, because the fish are still alive after six weeks it is unlikely to be vibrio or aeronomas because these generally kill within three weeks. Also the spine curvature is often a sign of chronic mycobacterium infection. Also fish tb breeds best in warm water, and the disease developed at the height of the hot season here.
I have read that if one of my fish develops tb, I have to completely break down my tank and start from scratch. My question is: can I keep any of my fish that are showing no signs of infection? Fish tb can be transmitted to humans so I don't want to take any risks, but I would hate to have to euthanise the ones that appear healthy if there is another safe option, especially my Hillstream loach who is two years old now.
Thanks for any advice!
here are my stats
• 40G aquarium
• 20 percent water change and vaccum gravel every five days
• Two filters/pumps, plus additional aeration via bubble wand
• Contains nine small rasboras, five rainbow fish (three large, two small), five glass catfish(4-5 cm length each), two albino coryadora, one Hillstream loach (scaleless fish), one red and white striped shrimp of some sort.
• Nitrates 0, all other water parameters in range, although my PH is on the low side
