my male swordies are acting like they are going to die Ammonia 0, Nitrite 0, Nitrate less than 5 plus I just did a water change with RO water (because my pH was higher than 8! Yes I acclimatized the swordies b4 ading them, 1/2 hr or so, and 1 female jumped out of the net ontothe floor, but she is doing fine and themales aren/t ??? ) They are up at the top, one is kinda sideways amd the other keeps going down 2 the bottom and laying there, then going back up ???
