Hello

In 2 of my tanks I have a male betta (ea) and even though the water parameters test ok (no ammonia, no nitrite, less than 20 nitrate) their fins are a little shreddy looking.

As for the specific males, one has been fighting fin rot since I bought him at walmart over a year ago, but up till somewhat recently I thought that for the first time I might get to see his fins in full glory, but then the ends started 'shredding' again. :( (There is no red on the ends.)
The other boy, well, he got himself eaten a while back (pics in photo album, labeled in various stages of 'Cheeto eaten'), so it could just be his fins are still growing back. Or not?


I'm just wondering, as long as the water parameters are regeristing at 0 ammonia and nitrite and not too many nitrates, do I need to do a water change?
Or could skipping changes have anything to do with fin rot even with alright params'?

Normally I change some water every week, sometimes 2x, but sometimes it doesn't get changed for a few weeks - like this last time- but everything (that I've got tests for) is testing ok without the water change, so I'm just very curious.
Thanks!

Agree. Keep doing water changes regularly.
 
i also agree. regular water changes not only keep your nitrate levels down, they also remove TDS (total dissolved solids) and DOC (dissolved organic compounds). build up of these two things can cause your tank to go downhill or even crash.
 
Yes, keep up with the water changes especially with those shredded fins trying to heal! Hope they make a full recovery soon.
 
how often do you think?

more often while their fins heal?

Thanks! :)
