The discus start to get skinnier since a month. Today he refuses to eat and lay down on a corner of the aquarium.

None medication but as of today he’s in a quarantine tank but its a 5 gallons (my usual quarantine tank have 1 month fry in it)

Thank you for your help, i'm desperate.

It looks to me like it's suffering from Heximita. Can you show a pic of the whole community tank so we can take a look at the other Discus? I don't understand how one fish can be in such bad shape if the others are doing well.

It doesn't look good for that fish at the moment but we will help you if we can.

[Arnaud612]

Hello,

Thank you so much for your help. Well i don't understand neither The other are sleeping behind a rock as the light is out but there is the couple.

The other fish look good. Someone more knowledgeable will see this thread and perhaps have a suggestion. I'm very sorry I couldn't offer help.

[Arnaud612]

I appreciate the help

Did you see the last video? I was thinking about rotten fin perhaps?

[LizStreithorst]

I just looked at it. It needs furan II as well as metro. I don't know if you can treat with both at the same time.

I'm sorry but your fish is pretty far gone. It may be a waste of money buying meds to try to get it well again. It pains my heart that I haven't been able to give you hope.

[Arnaud612]

Thank you... I don't have it and It's 4am here in France. Would you think esha2000 would work?it's the only thing i have right now.

[Second Hand Pat]

Hi Arnaud, I am sorry to tell you but the condition of the tail and other fins suggest the fish is dying. I do not think there is any thing you can do. If you want to try Furan 2 then give it a try and report back.

[Second Hand Pat]

I see you have esha2000 Arnaud. Do you know what it in it?
Pat

[Arnaud612]

Okay, i understand but i want to try. I never lost a fish before... I don't have furan II nor can i have it before tomorrow. I will try esha 2000. Thank you both from the bottom of the heart. Any idea what is his sickeness ? And do i have to worried for the other fish?

[Second Hand Pat]

Maybe age related Arnaud? It's condition suggests it has been struggling for a while. How do all the other fish look? Also are they eating well with dark poop?
Pat

[Arnaud612]

I think esha2000 is the european equivalent of furan 2. The waste of the others were white for a day or 2 then, i stop brin shrimp and it come back as normal. They are very active so i don't know. I notice them maybe one or two time scatch themselves against the plant but no other symptom. one of them had some white on his skin but it went away after a day or two. Other than that they are ferocious eater and my couple breed every week.

[Arnaud612]

Esha 2000 have some ethacridini lactas, cuprum, methylorange and proflavinae. Don't know if its help

It was actually skinny for a while but that's the only symptom. Today it went bad very very fast.They all have the same age. Could it be something in the water that only affect him because it was the weakest?

Furan 2 has nitrofurazone + furazolidone + methylene blue which are antibiotics.

Proflavinae might be a antibiotic and I think cuprum is copper.

Being the weakest fish does is not a good place to be. Perhaps the stress got it? Really sorry
Pat

[Arnaud612]

Yes it is copper Thank you Pat, really . I have methylene blue, should i add it?
