You get a 1/2 # bag of small granuals so it will last quite a while. With the zip lock bag it stays fresh longer and there is no bad smell. I have a Betta in his own tank who is a pickey eater but he eats this with no problems.I also have a 55 gallon tank with guppies and tetras and catfsih and they all enjoyed the pellets and I did not have the leftover mess like when i use the store bought flakes.Have been useing it for a week now and my water is not cloudy like some foods make it. #RankBoosterReview # Sponsored #SunGrow https://www.amazon.com/dp/B0723DJMMS/ref=cm_cr_ryp_prd_ttl_sol_0
