Yes those are bam bams. The color change is what is called color morphing. Happens alot with zoas.
so if i were to frag some of the greens off, would they maintain that color and form a new colony all that color?
Possibly. But cant say for definate.
The green is a morph from the bam bams. If you lool at it, youll see the rim is the same as the bam bams
Reef Octopus HOB BH-1000. Good for up 100 gallon. Quiet and works very well
+1 I have the BH-1000 on my 55g, works good, no complaints.
I did have to cut the intake pipe to be a little shorter for my water level.
Looking good.
What sort of clearance do you need Red Eye Reefer from tank to wall?
Im sure i have enough, just want to verify.
I want to say 4 inches is the minimum you would want/need, when I get home from work I can measure real quick for you.
It's pretty slender. I know for a fact 6 inches would be enough.
