I, personally, would stop using silversides. Myself and a few other experienced anemone keepers have had issues -- I lost an otherwise healthy H. malu after feeding it a silverside.

Same here, lost 3 healthy LTA's after one feeding.
Done w/ them, too many safer options.
I think this product is mostly iodine (?) I know that many fraggers use iodine as a dip with anemone-like creatures (mushrooms, etc). I myself have never used it so I am interested in seeing the results from people who have.
As far as silversides go, I tend to stay away from them as well as raw shrimp due to food safety issues. I am convinced that I have killed anemones by feeding them "bad food" - and shrimp and silversides seem to go bad more frequently than other food types (for me).
With the smaller guy you don't have to feed big food chunks. You can try creating a mash from blending mysis shrimp or other frozen foods, and then add some supplements (I use Selcon, personally). You can hand feed with an eyedropper by squirting some food GENTLY directly into the mouth.
The little guy has me worried. You are basically in a race against time. Until it heals its mouth (and actinopharynx and coelenteron) it doesn't have the ability to intake and digest supplemental foods. It is living mostly off of its body tissues, zooxanthellae, and possibly dissolved organics in your tank water. If you decide to hand feed him, make sure that he has a complete digestive system before you do - otherwise the food matter may not be digested and may just get caught up in body tissue and rot, or may otherwise irritate the anemone or disrupt the healing.
It seems to me that this is hardly even going against conventional wisdom, given that this type of propagation has already been done so successfully with such similar animals. I don't know that I'd try it myself but this thread is fascinating and I'll follow along. Looks promising so far and I admire jynxtrix's guts.
It's also interesting that Dr. Fautin in her statement says that what we think of as one species may in fact be multiple species when it comes to anemones that are known to reproduce asexually, but never seems to consider that the same could possibly be true for anemones that are not as commonly known to do so. It almost seems like there are a heck of a lot of things we don't know about anemones!
There is evidence to suggest that there may be two different species of magnifica and quadricolor. There are two different types, or forms, of quadricolor and magnifica. There's a larger, solitary form that is not known to reproduce asexually, and a smaller colonial form that regularly reproduces asexually. More research is needed, but due to these differences within the same species, we have cause to question the classification of these animals as it stands today. We have no evidence to suggest that any of the other 8 clownfish hosting anemones may represent more than 8 species.
Do we know roughly how many have tried? Is the success rate zero, or less than 50%? How do we know that everyone who has tried has failed? Define failure and success. Is one piece surviving failure? I wouldn't call that failure, exactly.
