growth rate multiplier? sibling frags

[karimwassef]

Well this makes perfect sense to me and I have noticed it as well. The total perimeter of the coral (previously two corals) has decreased by their merging. The same amount of energy is able to be used on a small growth perimeter => greater growth rate.

If I add the area of two independent frags and compare that to the area of two touching frags, the sibling growth is net higher. If it's just redirecting the growth, it would net the same overall.

Area is one variable - I also notice that the count of branches and length of branches is higher too.

To do this right requires controls. Weigh six frags, put three next to each other and the other three separate. Measure the growth rate weekly based on weight gain... Plot the results after 3 months.

This may also vary by species or growth type: encrusting, plating, branching, mix.

The area should not be the value of interest as the coral grows outward from the perimeter/growth tip(s) not along its entire area. But I agree to get actual data for this weighing of each specimen is necessary.
