Best Vitamin B3 (Niacin)-Rich Foods for Freshwater Fishs
Ranked by vitamin b3 (niacin) content among foods safe for freshwater fishs in the Creature Feast catalog.
#1
Bloodwormsper 100g freeze-dried: ~2mg niacinBloodworms are a good source of niacin (B3), which is critical for energy metabolism and DNA repair in freshwater fish. Niacin deficiency in fish can cause skin lesions and poor growth, making protein-rich foods like bloodworms important contributors to B3 status.
#2
Brine shrimpper 100g freeze-dried: ~1.5mg niacinBrine shrimp contribute niacin as part of their complete B-vitamin profile. The whole-organism nature of brine shrimp means the niacin comes alongside tryptophan (a niacin precursor), effectively doubling the B3 contribution.
#3
Peasper 100g shelled: ~2.1mg niacinPeas provide plant-based niacin that contributes to the overall B3 pool for omnivorous fish species. Combined with the niacin from their protein-based foods, peas help ensure adequate intake across the diet.
#4
Spirulina flakesper 100g: ~12.8mg niacinSpirulina flakes provide niacin as part of their comprehensive B-vitamin complex. The niacin in spirulina supports the NAD/NADH coenzymes that drive hundreds of metabolic reactions in fish cells.
