How much and how often?

i cant think · Apr 11, 2022

I have a 2 inch deresa clam (Measured him yesterday), now since it’s a juvenile I’d assume it takes most of its food from the Zooxanthellae and Phytoplankton from what I’ve read about them.
My question is, How often and how much phyto should I feed him? At the minute I feed him 2ml every day around 1-2pm. Is this an alright schedule to start him off with or should I feed him more?

Phyto isn’t really important. Derasas are easy and live from photosynthesis. They also absorb organics and N, P from the water column.

Thanks for the help, I keep on reading about how phyto is important for juveniles and assumed that until they were large enough they didn’t take in a lot of Mg, Ca, KH, P, N ect… and instead got their food from phyto and other plankton in the water column.

Here’s what algae barn say about deresa clam feeding;
“If it is under four inches, feeding is required for Derasa Clams. Smaller clams need to be fed phytoplankton a few times per week to keep them alive. When the clam gets larger it is still beneficial to feed the clam phytoplankton or just add it to the tank, especially if your nutrients are close to zero.”
