All, updating the first post now - Slama, if you need a small amount, work out splitting 1/2 block with soneone at the swap - they best I can do is 1/2 blocks - and that's a RPIA.
Tunicata, see above - maybe you all can get together after to split the 1/2 blocks.
Leslie, krill is ocean krill, and yes, like the whale easts - NIkki - without an established tank, you may want to consider 1/2 blocks to start - the mysis alone is 4.4lbs of food.
Hope that helps everyone, LMK if you have any questions.
