HELP!!!!! All of my bettas have holes in there fins it started with one and now all of them have it it looks like you know when a bug eats a hole in a leaf what do i do?
Ok from the sound of it I think your betta has fin rot its pretty easy to cure so don't worry to much just go to your pet store and buy a med for your betta after a while he should be fine
What are your water parameters? Size of tank and tank maintenance schedule? Do a water change daily by 20% until the fins heal completely. No meds are needed.
to every one that helped me all my bettas are doing fine and looking very well i only lots one my silver and blue male betta but the rest of the are doing very well so thanks to all
