I just got a bubble coral - white, with flourescent green tint . I've placed it mid height in my 46gallon under ~200W of PC
lighting. It expanded right away and seems pretty happy, but I have a couple questions.
1. They say to place in "medium" flow, but I just hate those relative terms. What might be medium to me might be low to others. I'm guessing you don't want the bubbles getting beat around too much - that's probably be too much flow. But is some gentle movement of the bubbles OK?
Seems like with how thin they are, they're going to move with the smallest of flow... I just don't know how much. I'm guessing if they're not expanding fully, then it's too much flow?
2. Regarding the expansion of the polyps, do they kind of ebb and flow through the day? Seems like they get realllllllyyyy puffy, then decrease a little bit, then get puffy again. They don't contract fully like at night, but they just don't maintain the same size throughout the day. Is this normal? Is it their form of flushing water through their system? Or is it a sign of too much flow?
Thanks in advance!
