I just want to say that my L241 died to days ago with the same symptoms one of my L240s died two years ago
In just one day his belly became swollen,he moved from his favorite retreat to another which is close to an airstone and the evening he moved up and stayed just under the surface breathing really fast.I medicated with Octozin when i first show the symptoms as i had successfully treated it in the past with this but in the very early stages.It seems that was too late and he died during the night.Next day i found him under the mopani wood and i thought he was alive and better.Later i checked again and he hadnt moved at all.So i picked up the wood and saw he was dead.He had two sores on his sides and blood was coming out of his mouth.Really disgusting and sad .Anyway,i would like to ask you if you know what has caused his death and if there is any way to treat it faster because this disease proceeds too fast.Water parametres are:
pH 6.8
NH3/NH4 0
NO3 <10
NO2 0
The tank is 55g and the tankmates are one L240(6") and one L190(4").
Thank you in advance
