Growing sun coral babies

[dendro982]

Please, share experience on growing sun coral babies (spawns?), particularly target feeding.
Also, mention the size of the system and how do you handle bioload (filtration, skimmer, refugium, BB or DSB).

My old chronological thread is here.
I'm keeping them in nano-tank, fed by dried Cyclop-eeze, don't like speed of growth compared to my big tank with another group of spawns (same spawning event and another one), tank is fed by frozen mysis.

Several months passed, spawns are still of the size 2-3mm (3/32 - 1/8" body diameter when open), may be it's time to start target feeding?

Systems:
6g Nano-Cube, night filtration only (with filter floss), no skimmer, no refugium, was SSB - removing it gradually, as a source of debris accumulation, especially under the rock. Have in-tank macroalgae - it catches uneaten food too, will remove it or the non-photosynthetic corals - tank should not accumulate decomposting food.

90g is a BB tank with messy not reef-safe fish and dragonets, filtration: canister and micron sock, oversized skimmer, small refugium.

I don't have any experience with them myself, but a friend has one and feeds a few different things, including my live adult brine shrimp.

I meant the small, of this size:

She feeds the babies that are in between the grown ones, the same as the grown ones get, cyclopeeze, blood worms, frozen brine, mysis, and live adult brine shrimp, although you could target the little ones with live newborn nauplii instead of adults I guess.

I got your point, thanks!
These are slightly different, much smaller (some are of the size of the blood worm's head), settled separately from the main colony and are already several month old. No problem with feeding the small one between the big ones - they are much bigger, and receive more than enough food during the main colony feeding:

See below the small separate one on the left - for comparison with the new polyps within main colony:

Anybody else to share experience?

The small ones between the large ones were not always that size. They all start out from basically something you can't see and grow accordingly. At first, I believe the smallest stages can be fed by the zooplankton available in the tank as they are so small, but eventually you need to give them something of appropriate size.
Like I said, I don't own one but if I did and was concerned about the smallest ones, I would probably start with culturing rotifers and feeding those to the polyps, and progress to the cyclopeeze and then to larger frozen foods as growth occurs.
Sorry I don't have any other ideas.
