I know for darn sure that I'm not the only person on here experimenting. What are your observations? Here's a couple of mine; Anything in the Dendrophyliidae Family (Dendro, Tubastrea, Duncanopsis, Turbinaria, Balanophyllia, etc) can be target fed meaty foods 10 times/day if you had the time. LOL Seriously. Nannochloropsis phytoplankton is pretty much worthless with most of the species of non-photosynthetics. (Not just corals, many feather dusters, scallops, tunicates, etc). I'll use my watermelon example here. If you had an armless, legless, and toothless man that was wasting away due to starvation but if the only food you have available to try and save his life is a watermelon, he won't have the capability to gum it down to a smaller size so he's going to die. The watermelon is just too big to eat. Look for smaller species. Everyone says that sponges are non-photosynthetic. Some are non-photosynthetic, but some will only live with fairly intense lighting. Some species do quite well on nothing but nannochloropsis.....other species want the smaller species of phyto. Once you find a space in your tank where it's happy, DO NOT MOVE IT NOR THE FLOW PATTERN IN THE TANK. They can, and will, move their osculum for proper circulation. However, IMO, this is stressful on them. (I have no scientific proof of this, only observation). Tunicates need a species tank. Don't put it in your reef. It will die. The next time I feed mine, I'll try to remember to take pics to show you how green I make the water (they don't like nannochloropsis) and then I will take a picture. Then I will show you the pictures a couple of hours later. The water will be clear. It is truly amazing. They eat more than a 13 year old boy. Scallops are easy to keep with the right type of phyto. Most articles say they should be left in the ocean but I disagree....just don't feed phyto too big for them. (Remember the watermelon example. Also remember they are short-lived even in the ocean). Some gorgonians are photosynthetic and some are non-photosynthetic. If it's really colorful, the likelihood is that it's non-photosynthetic. These puppies are VERY PICKY about flow. If they are doing well in your system, don't move them. Even Cyclopeeze is too big for them. Oyster Feast, rotifers, and other very tiny zooplankton is needed. Mine have been doing well with additional Reef Chili and Zooplanktos-S. Now that I'm out of both, I'm going to experiment with the Fauna Marin products. (Interestingly enough, at MACNA I talked with the rep of Fauna Marin and they want their products combined with Oyster Feast so I guessed correctly). WHAT ARE YOUR OBSERVATIONS?
