Ok I have been keeping acans for a long time and have great luck with them growing but they always seem to grow into a mound with smaller acans always being shaded, in the past ive always just broke the rock underneath and tried to lay them flat with glue, it works but only for the ones you had already not the new growth. Ive been talking with a friend who has the same problem and i didn't really think much of it till ive been starting to see colonies with less heads than my own but they are growing flat like that classis acan colony you see everywhere. Any help would be appreciated.
