Post subject:  Worst time for Sydney trout to get finrot
Found this floater this morning with what appears to be bacterial finrot. The base of the
anal fin appears to be red. Another 5 or so with whitish dorsal fins, still hitting their food real hard.
Trouts are in the same tank as the silvers, and share the same water with some catfishes. No silvers or catfish have yet shown any symptoms.

I have salted the tank to 6 ppt with the intention of doing a 50% water change after a week (assuming, I see signs of improvement). How quickly do they respond to salt? I have some concerns for the catfish with that level of salt, so I might try ang isolate them.

Any suggestions? Isolate the trouts and hit them hard with salt?
Ammonia 0, Nitrite 0, Nitrate 25.
Dead fish 19 cm.

What's your pH....

That fella has been dead for a day or two... and the tail fin may have been nibbled by others...

Good to hear from you... is that the only fatality out of the lot I dropped to you???

P.S ... what's your water temp up that way after the warm weather???

Hi Rupe,

temp at 17c, just check ph and i'ts 6.5, I have nothing right now to increase ph so I put coral rocks. All my previous tests were 7.2, that's why I stopped testing for ph...bad move

and Yes Rupe, it's the first casualty (hopefully last). This bunch of trout actually performed waaay better than my batch of silvers. Why Rupe, are you having doubts about your delivery prowess? LOL

Nah... no doubts about delivery... just wondering about your fish keeping skills... :lol:

Kudos... you've done well mate...

pH 6.5 isn't a panic point.... so just get some shell grit and add it to the water return.. or inlet to the growbed... or bury it in the growbed...

fish keeping skills- guilty as charged!, but I'm learning, due mostly to this forum... thanks everyone.

Trouts have improved.. I can't see any signs of redness on the base of their dorsal fins.. a few of them still has white dorsal fin tips.
