baking yeast and water

[glxtrix]

anyone ever feed their clam this mixture? Been reading a lot about clams, looking into getting a crocea. Just trying to cover all avenues befor buying. Thanks.

Never heard of it and as far as I understand your clam is not going to consume yeast. It will consume phytoplankton and phytoplankton only.

Wrong. It will indeed consume yeast and zooplankton, and many other particulates. However, that doesn't mean it gets much if anything from it.

I haven't found any solid evidence that yeast is particularly useful to tridacnids - and to the contrary, Braley (1993) wrote that using yeast to feed larval tridacnids had been only "marginally" better than feeding them nothing at all.

It's also very easy to overdose, which can quickly lead to outbreaks of unwanted algae.


Here's the ref.

clams will eat more then just phyto. the ideal size range for foods for clams is between 2 microns and 50 microns(this size has the least rejection) but clams have been reported to feed and digest foods up to about 250 microns. clams will feed on phyto, bacteria, microzooplankton and detritus. Danial Knop makes a yeast based clam food(coralvit f i think). anyway if your clam is over 3" and your lighting is strong and your system is well established you shouldn't need to feed the clam
