Last night I noticed my male guppys tail looked like they had fin rot. The tips are getting stringy and turned white. This morning I found that there is a chunk out of his tail, probably a 1/5 of his tail is gone. Is this Fin rot? and chewing?
I do not test the water, unfortunately. I have airstone, bubbling constantly (a lot of bubbles) and filter. Temp 82F. I will try to get medication, but petstore is not open today (i live in small town). I'm worried because he often swims with my female guppy, who is pregnant.
Jefwic im really sorry about your loss. Have you tried keeping Platies or Swordtails? as they are stronger than guppies, i was adivised to give up keeping guppies and turn to platies and swordtails instead.
