Ok in my 29 gallon tank i have noticed my guppies are getting finrot. I thought i saw this last night, but couldn't get a good view to tell. Today i sat and watched for a while, almost all of my guppies have finrot starting on their tail. It is not bad rinrot just frayed edges. I have tried the jungle fizz tabs but don't want to go that route again. My tank is on last stretch of cycle before it is complete, i will test water tomorrow morning. I am wondering if i can use melefix in the tank and will it be safe for my kuhli,dojo,black loaches? I am done getting guppies as they are the only fish i have had get sick on me.... seems like they always get finrot. I have increased the water temp to 82 and added aquarium salt to help disease but no luck from what i can tell. The fish seem ok just that thier tails are frayed... sometimes i see them "relaxing" toward bottom of tank, not sitting on bottom but hoovering around a shaded place. So what is best treatment for finrot? How long does it take to cure if i am successful in treatments?
