I agree with lemonade. IMO, the most critical piece of getting wild/mari tenuis to [not only live but] thrive in captivity is getting our tank water parameters as close as possible to the NSW. I'm guilty of saying "getting the water as close to NSW" but the more I think about it, the statement may be too generic. I think I'm missing, matching NSW from where the acro's come from. We all know that water parameters and temperatures can differ significantly when compared to different areas of the world's oceans. After 26 years of serving in the Navy onboard Submarines and Surface ships, I've been around the world dozens of times. During port visits, I've had the privilege of snorkeling/diving those oceans and they feel different, look different in colors, clarity, cleanliness and fish density.
This probably sounds funny but I also wonder if the nutrient levels and more specifically, types of nutrients play a more significant role. Maybe the OceanMagik, PHYTO-FEAST®, Reef Roids, Aminos, etc. that we buy actually don't "taste good" to the wild acros? Is it possible that we are starving them to death before they have a chance to acclimate to the new food source? For example, Japanese Food here in the States didn't taste the same as the food in actual Japan - after 2 years in Yokosuka, when my family and I came back to the States, we had to re-acclimate because now State side Japanese food tasted funny to us. Are the corals experiencing this as well? Although the Stateside Japanese food became nasty to us, we were able to eat other foods so we didn't go hungry. The corals don't have that option but we were able to find a great new Japanese steakhouse eat at.
I know that we talk a lot about lighting but how much time do the corals in the wild spend in the ocean as compared to time spent in the sun? Most corals are in the water 24/7 (with some exceptions of shallow water corals that experience low tide exposure) but the sun isn't available for that same amount of time. Lighting types, adjustments, consistency, etc. are easy...reaching and maintaining water parameters is more challenging for most. We see this all the time. I've only read a billion times where great reef keepers such as SBB are asked for water parameters or their secrets for having eye-popping corals.
Has anyone done a comprehensive ICP / Scientific type water analysis [and actual food types/sources] for those key areas where our most color corals come from? If so, can someone point me in that direction so I can read up on it. I want to try to step up to the challenge of improving the survivability rates of the wild/mari acros.
