Codium, my codium. . .
Codium, my codium. . .
If it's the same 'codium', it grows like a 'gordian knot'. . . interweaved. Quite highly calcarous. . . so all but the most persistent tangs should leave it alone. Grows steadily and non-fussy in general. I picked up my parent stock from a LFS where it arrived by accident with some live rock. . . and grew to where it was starting to look like a 'display' item.
