Hello,

I have 3 betta that is staying with me.
Recently I have a 1year 5months old betta passed away due to Fin Rot.
I didn't give him any medication when he got the disease. All along i did was just change the water of 25percent daily. But sadly he suffered 8 days of Fin Rot before he died.
I did research that Fin Rot was cause due to bad quality of water or stress. But their water is pure clean and I treated it with prime all the time. I change the water one a week of 50percent. Im still confuse why my betta have Fin Rot or maybe it is a common disease for betta. Or perhaps because of the ornament and moss ball, I don't usually take out and wash at all? Oh, they are staying 5g each.

As to prevent my another 2 lovely from Fin Rot again, I would like to know how can I deal with Fin Rot.

Also, I just found out that aquarium salt does help. Anybody who has experienced maybe can give him some advise how to i cure it when I encounter again.

Thank you.
