why the puddle effect

[Doug]

Nothing wrong with those corals. They grew up here.

I wonder if when you see larger colonies of someones acro, the base is not larger than one thinks. I thought I once read that a healthy acro is one that encrusts a good base first? If the coral just grew vertical and not horizontal, I doubt it would last for long in the wild.

I think the one your most concerned about Mike, has decent vertical growth also, at least, IMO
