Looks good, the Macrandra is forming a nice arch there at the back. Looks like you have Glosso, Lilaeopsis, Pogostemon Erectus, dunno what moss it is and some Moss balls.
Great little tanks these ARC60's Just re done mine.
Tidied up the tank by removing rocks to make some more room for plants and swimming also added a little division for the carpeting plants, here are some photos...
Also thanks for the advice steveo its worked perfectly, amazing how plants work!
