Could Someone Recommend A Good Supplemental Food For Tree Sponges?

[vonjankmon]

Just got a pair of red tree sponges in today, they're currently in my quarantine tank and I was wondering what supplemental food would be good for them? Seems like every webpage I can find says dissolved organic supplemental food but doesn't give any more information that that. Since the quarantine tank is almost totally sterile I doubt they'll have much to feed on in it unless I add something.

Any advice or recommendation would be highly welcome.
