So I added 1 cleaner shrimp and 3 pepperment shrimp to my 29g biocube tonight. Since I have no fish in there yet I went ahead and bought some frozen food for them. I was planning on feeding 1/4 of a cube 3 times a week ( as suggested by the LFS) but not sure how to go about it! Do you just thaw it a little and then just throw it in or do you have to hand feed them? I really don't want to be sticking my hand in there but will if I have too!!
