perfect water chemistry ,do not bother it ,lite current and time,feed it very small pieces daily.i have had some success with this only with a wall frogspawn polyps started to ooze off like icecream melting.i dipped it and di exactly what i wrote and it took 2 months but it came back.i only buy branching now cauese if a head dies you can cut it off not with a wall though.walls are better looking though
