Right now im using Hikari Algae wafers which i have always used and im very satisfied with it. I've basically ran out of it and will buy another bag but before i do, im just curious if theres another brand out there that is preferred. Also, i want to supplement my shrimp/snail with possibly an addtional source of protein and calcium. I've been looking at Hikaris Crab Cuisine, is there another brand i should be looking at? thanks
