The top one is right under the HOB filter and getting great flow.
Running 150 MH 20k for lighting so it's pretty happy and spreading since I purchased it.
As far as the bottom one, do the polyps on caps open up? Seems like they're just out and not fully opening cept for the new growth. They've been in the tank for about 3 months and growing pretty good.
One time they were bumping uglies over night and the cap looking one started getting kinda fuzzy and polyps receeded and turn white.
I'll google nodosa and see see what comes up.
Thanks for the Info.
