Actually, most of "our" tanks are very un-natural because in the reef world, areas are normally dominated by a few specific corals.
They don't normally grow together in such diversity as most of us keep, except in very specific locals.
Or so I've been told and have seen.
So it becomes VERY important to know the nueances of all of our critters so that we can keep them "playing nice" together.
LPS-SPS VS Softies-Leathers coming up next on
"what the heck keeps happening to my " blank " ??
I suggest a couple of books to really educate yourself.
"Reef Secrets" - Nilsen and Fossa,
" Aquarium Corals" -- Eric Borneman
" Reef Invertabrates" --Calfo and Fenner
With these three books in your possession, it will be hard to screw up. All three will cost you about $120.00 TOTAL
VS $hundreds and hundreds in little mistakes.
Also great fun. Not all HARD science.
yours in interest and goal,
