I originally started using capelin fish roe in order to get difficult fish to start eating instead of brine shrimp which has minimal nutritional value unless gut loaded. However, I found that my fish go nuts for it, especially angels, butterfly fish, anthias. Who else uses this? I also tried salmon roe but that is so much larger in size that the fish had difficulty. Anyone else feed this stuff? I am also just starting to feed black worms, I will keep you posted on how that works out.
