Feeding Ghost Shrimp (natantia Gen. SP.)

[AC2020x]

Hello,

I am using large quantities of live ghost shrimp (hundreds/ week) as a food source used for squid.

I have been feeding them with tetramin flake food, however I would like to switch to a less messy pellet food. Using this flake food makes it difficult to keep the system clean.

Are there any recommendations on a food in which to use? Preferably it must be found on Dr. Foster & Smith.

Thanks!
Andrew
