When one of my guppies started swimming sideways, i quickly transferred it to a small tank, treated the water with conditioner before and within a day it was back to swimming normal. I placed it back in the main tank and it has been fine ever since.
Ok but like, what if all the levels of everything in the tank are correct and theyre swimming like crazy? These videos never help, they're too generalized for a lot of situations.
Once again I thoroughly appreciated your content ; always very informative and the community tank at the beginning is lovely. Perhaps you can do a special on planted/ guppy community tanks 😉👍
