Thx manClean water and close observation sounds sensible at this point.
Don't be angry. Our hobby is a gamble. Even keeping fish solo but much more so keeping communities. You gotta know it going in.
Any updates?
Agreed though i'd like to keep the male i dont have much attachment to him. I'd let him hang in the 75 for a while but im not sure if he'd try and make a snack of the H.platyrhynchos.I hope it works out eventually... if not you have two gorgeous females.
