Two males, probably both from the same supplier. Admiral was a rescue, underweight, sickly. Dusk was a healthy male, but weak internally.
Dusk died yesterday in the 10 gallon. He had ich (not the killer I believe) so did simple water change, everything proper, water temperature perfect... He died. Today Admiral was fine when I left today, came back and he is dead. Water temperature was good, levels were fine...
Now I have a third male - Crayola Colors. He is from Dusk's batch but seems a bit more hardy. Why are my males dying one by one without a visible sign??? I'm going to clean the ich tank with hot water and all that, change cartidge, and add filter media from my healthy tank. I have two new females (now I worry for them as they are from Admiral's batch) I don't want to lose my three possible bettas!!
What's happening? :(
Water quality: great
Temperature: 26 degrees celcius
Need any info just ask... Just please help :( this has never happened before.
