reason to hope
Vienna_24.06.20_04:22 pm longfin still worries me as well. He now has wounds on both sides and looks a bit mangy. He used to be the most splendid looking fish among the fish in my aquarium. I hope he will survive. There is reason to hope, as it seems that mdm, who has had similar symptoms, … Continue reading

Vienna 24.06.20_04:00 pm When I got home last night, 2point was floating on the surface. I was sure that he was dead; but he wasn’t. He shot away as I approached him.

repetitive behavior
longfin has wounds similar to mdm. I still cannot say for sure whether they were caused internally or externally.
