Hi There

I have a problem with one of my Trout.

A few days ago I noticed its tail starting to go white. So I removed it from the rest of the trout and place it in an unused Aquaponics tank. Ammonia, nitrite and nitrate are all at comfortable levels. PH was at 6.6 but adjusted this to 7.

Anyway as you will see by the picture, the whole till is now a swollen white. and the little bugger is having trouble swimming!

This was the smallest fish in the tank and thought it mite be stress. Is this the case or is there anything i need to be worried about?


Cheers

Allam

I'm coping with trout disease now as well. I am fairly certain our galvanized tin roof leaked zinc into the fish tank. The Brook trout had blisters all over. It was horrible and I felt so bad that I let it happen without figuring out what had happened over a matter of weeks. I suggest you take whatever this is seriously. Inspect more fish to see if it is starting on the others.
Are the trout indoors or outdoors? Research trout disorders on line as well as ask here.
here is one of may. It'l take time to figure out a prognosis http://onlinelibrary.wiley.com/doi/10.1111/jfd.12241/pdf
Good luck.

I see there is an ulcer near where the skin starts to go white (low on the end toward the head). I'm not sure you can save this fish but it might be good to isolate the fish just in case and also for any treatment.

Boomahay I lost a batch of Silver Perch nearly 2 years ago due to 1 galvanised bar above the sump corroding after I salted up, it was underneath one of the grow beds and couldn't be seen and I hadn't noticed it until after I lost the fish by then it was far too late.

I've since removed all gal from anywhere near where it could have any contact with the water and completely flushed and thoroughly cleaned the whole system including the K1 bio media. I have had no problem since and have had 2 batches of fish in the system after the problem.

As Boss said I also first noticed a fish with blisters and removed it from the tank, then on further inspection of the other fish most of them were far worse than just blisters, with scales and skin fallen off similar to your Trout.

The 2 fish in the photo below are the best and worst effected of the batch.

Hi Allam,

I had a similar issue you can checkout the posts from 1 Veiwtopic below page 15 8th post down.

"I read about saprolegnia and how to reduce the chances of getting it.

I've since vacuumed the FT, turned the aerator up to 80% but can't do much with the PH as it's already high.
I've dosed with another 3.2 Kg of salt to bring the system up to 3 ppt (the strawberries arn't going to like it).

Saprolegnia is more likely when there's lots of dead fish and other rotting muck around which makes me wonder about killing slugs in the GB with snail bait - if they slither back down into the rocks they'd be adding to the saprolegnias food supply."

The main thing I do on going is vacuum the muck off the base of the tank at least once a week and haven't had that issue again. None of the infected fish survived.

Thanks Joeblow. It is so nice to see you're making it past the health stuff and of course being here with us AP Nuts. Indeed trout won't live with slightest bit of zinc.
I just wish I would have investigated what was happening here at home more from advice I received here.

Perhaps we can make a poll asking users to list fish diseases they have incurred and hopefully resolved. While the results may not be large enough pool to be scientific, we may see some trends.
Afterward, we could compile a trouble shooting list for common fish ailments. On the other hand this probably been done, as the best group of experts are here.

Although I usually don't reply to single posters I had this same trout issue where the skin seems to rot off around the tail area. At the time I put it down to a fish fungus issue and was brought in when fish were brought in from a fellow APers tank.... I salted heavily in my hospital tank, 10ppt from memory. The celery tasted great!
The majority of the trout recovered and also tasted great.

Hi Boss, Yeah getting old is great fun and the thing is we are both going too be older tomorrow :laughing3:

I forgot to mention that I completely flushed my system with an industrial strength hydrogen peroxide to make sure there was no nasties left over.

Skeggley I also salted up and sampled the Celery you speak of, it certainly took the salt up :upset:

What is your water temperatures? I have seen what is in your picture several times and always makes me queasy. I have an idea what it is but I have to go double check.
