Highlighted Reviews
"My BIG goldfish love these whopper sinking pellets! The only challenge is for some to actually make it to the bottom of my 75 gallon tank so that our Corydoras catfish and our Plecostomus can get some nibbles too. Never have a problem with uneaten bits clouding the water."
"I bought this food for my frontosa. I was using it for 2 weeks. Feeding her once a day (6 pellets) for 5 days a week with 2 separate days off of eating. My tank had a nitrate spike and after several water changes, now my fish seems to have swim bladder."
Bottom Line
For those with large fish like goldfish and corydoras, these pellets are a hit. However, be cautious with finicky fish or those prone to swim bladder issues. Be prepared to monitor water quality diligently to avoid issues.
