Cory With Fungus

[discus dreamer]

Any suggestions for treatment please
I have a cory strerbia with fungus. I have treated it before with interpet antifungus and thought it was better so returned it to the cory tank. Unfortunately the fungus has flared up again and he now has cotton wool like opaque patches in several places. I have treated the whole tank (5 cories) with pimafix and it is now day six of the seven day treatment and no improvement. Any ideas for what to try now. I didn't move him to the hospital tank this time as the whole tank have been very nervous since a move and changing to sand and i can't catch him without quite a bit of chasing around, also i think at least one other has a bit of fungus as well. They are eating ok (excited about some live brineshrimp) but very shy and hiding. My stats prior to the treatment were Amonia 0 nitrite 0 nitrate 25 ph 7.
thanks

If no myxazin go in with anti internal bacteria med by interpet and pimafix.

If no myxazin go in with anti internal bacteria med by interpet and pimafix.

I would either try the interpet antifungus or myxazin and continue with the pimafix as well until its better. Is there any damage to the fish that might have started the fungus problem off?

Any chance of some pics? whats the temp of the tank, other inmates, substrate, any sharp decor?

How often do you do a water change and hows the tank filtered and whats the nitrates in the tap water? as 25 is a little too high I think, I would be happier with it at 15 max

Dont bother with anti internal med as fungus is an external problem

thanks Wilder and Paul
I will see if I can get some myxazin and continue with the pimafix as well.
There was no damage although the fungus did seem to start in one discrete patch on his side and when i thought he was better there was still a mark there and it is this patch that has the most standing out area of fungus now. The tank details are 56L with 5 corries and 2 black widow tetras. I do water changes 20-30% about once a week. Temp is 28 degrees. The filter is a small fluval internal one and i clean half of that in old tank water about every other water change or more often if it sounds noisy. There is a sand substrate and lots of plants with CO2 added. I could add my hospital tank filter to see if that helps with the nitrates but I think they are about 10 from the tap. The nitrates are currently about 45 in my big tank and don't seem to want to shift from that even though I have been doing extra water changes.
thanks again

Why is the tank so hot? 28 isnt needed, you would best off at around 24, the fish will also live longer if you reduce it. Although sterbai are ok at that temp, not many other fish are.
Its going to take time to get the nitrates down, 45ppm is far too high and will start to effect the health of the fish. If you do a 50% water change, if my maths is right, you will end up with it at 27.5ppm as you have nitrates in the tapwater, so you either need to do more water changes or add plants/use an ro filter to keep the nitrates down

My understanding is that Corries prefer 28.
The problem with doing water changes at the moment is that I am six days into treating them with pimafix so I aim to do a change after the 7th day. Alternatively I guess I could just replace the amount of pimafix that is taken out, but that would assume that it remains suspended in the water.
Anyway I think I will wait another day to finish the treatment and then do a water change before starting the myxazin and pimafix strategy.

No, sterbai, adolfoi, duplicareus, C121, gossei and a few more do, most prefer cooler waters at arounf 23-24
Have a look round planetcatfish for more info

double post....

 

[discus dreamer]

OK have done a roughly 30% water change
have lowered the temperature to 26 because of the fungus
have added myxazin and pimafix and will each day for full treatment
have moved the internal filter up a bit to get some surface agitation
have added an air stone and will switch on for a few hours a day (too noisy to run all the time)
hope this all works because the poor little cory looks like he is wearing a fur coat now.
thanks for the help, will let you know how it goes.

How they doing the corys bless them.

I agree with Wilder go with myxazin or Interpet No'9 (anti bacterial) carry on with the tea tree based stuff it will help, but won't completely cure.

Sterbai corys will be fine at your temps, these are a popular choice for discus keepers as they do well in warmer temperatures.

Why would you want to use and internal med to sort an external problem??

Thats what I said although I think thats a little high for the tetras though personally

progress report
am keeping up the treatment and the cory that looked like he had a fur coat is a bit better, back to patches of fungus particularly one area standing out, which is I think where it all started. All the others seem ok but still much shyer than before i moved them around.
Sorry I can't get a picture but i have to sit on the floor some way from the tank and very still for about 10 minutes before they show themselves at all.

Good news! Cories are just incredibly resilient.

I have had some fungal issues this winter. But they are resolving. One bronze is pretty far along. I treated with Maroxy. I will do more about it soon. But I expect it to be okay. I lost a Brochis in the fall and oddles of harlequin Rasabora and one Melantanaea. (I'll look up the spelling later.) Then my second male agassazi red tail apistogramma succumbed to the MelaFix treatment.

Hope your Cory keeps improving.

 

[WILDER]

Keep going with the meds, good luck.
