Hi,
A while ago I lost 2 male convicts because of a disease I don't know. Just bought 2 females for them, so after the males died I bought 2 new males.
1 of the males is already having the same disease that the other 2 had.

The fish are in a 190 gallon / 720 liter tank. Ammonia and nitrite are 0. Nitrate is 10-15, PH +-7,5, used a testkit from Sera. Didn't test GH and KH.
Temperature is about 27-28 celsius / 80-82 fahrenheit.
The tank is running for 1,5 year and properly cycled, the old 2 males where in the tank since the start. I have 2 Eheim Professional 3 2080 running, and change about 50% every 5-7 days.

Other tankmates are 2 Green Terrors, 2 Jack Dempseys, Vieja Maculicauda, 2 Flyer cichlids (Archocentrus Centrarchus) and Amphilophus Amarillo. None of the tankmates were stressing the cons (not even the Amarillo).
Didn't add any new tankmates, only 2 new male cons after the others died.

I feed twice a day, Hikari Cichlid Gold and frozen foods (Bloodworms, Krill).

The weird thing is it only seem to effect my convicts. And it came out of nowwhere. One day they were acting normal and the other they were hanging down and not eating. Couple days later they died. I give this new male 3 days max. before he is dead as well if I don't figure out what this is. Symptons are not eating and hanging in the corner of the tank. The scales seem to be rotting away, in just a couple of days.

With one of the males I used salt and a medicine that had a wide range of disease would cure.
On the second male I used a a medicine for the bacterial infections. Both of the methods didn't work. Not even a bit.

Hope you guys have enough info and know what it is? I added some pics as well (water was green because of the medicine). Thx in advance.

I guess this is called an "ulcer" (I'm Dutch never heard of that word). Been searching on the internet and I read that it's a bacterial infection. Is this right?
 
That is rather strange!

Quite a coincidence, I'm in the Netherlands as well.

Either way... perhaps what you should try doing if you can is have a small isolation tank where you can put your new fish before mixing them with the rest. You've been lucky with the disease not spreading for the time being, but if I were you I wouldn't risk it further.

Try a fish shop called World Wide Fish in Rotterdam - I got my convicts there and they were very healthy and happy :)
 
looks like a bite from another fish maybe they telling you they need more space 8 larger and more aggressive fish in the same tank with no signs of spreading diseases or water problem seems like a no brainer to me good luck with whatever you decide to do
 
Bacterial infections can often wipe out just once species of fish in a whole tank, even of varied species.
 
looks like they have been hiding up against the heater and cooking themselves......then the bacterial infection does the rest.

Yes I am going the isolate new fish from now on. Right now I've put the convict in is own tank with some medication for bacterial infections and he is actually doing a little better. Today he was eating again and looking a lot more active.
Hmm.. World Wide Fish, never heard of that, think I'll go check it out soon.
 
World Wide Fish is in Rotterdam, and I bought my male con from him.

He was an extremely healthy guy - and full of personality as well.
