My betta has been eating the spirulina pellets consistently. The fish shows better color and activity. The pellets sink well and don’t create much waste. I appreciate the probiotic content for digestive support.
Jack Mitchell –
Great product for herbivorous fish. The pellets are easy to feed and the fish seem more active. The sinking feature helps keep the tank cleaner. A little more variety in diet would be nice, but overall very satisfying.

Used these for my angelfish and they’ve been thriving. The color has improved noticeably. The pellets are well-formulated and the fish don’t seem to waste much food.
