If your goldfish has digestion or flotation/SBD issues, I highly recommend this product. It seems to be the correct protein:veggie ratio for goldies. Plus, it is made of high quality material. I find most commercial dry foods have waaay too much protein content for omnivorous fish, but soilent green has higher concentration of greens which is similar to what goldies would eat in the wild.
I use this for my goldfish. He no longer has digestion or flotation issues. Originally, I used the Wardley flakes but my goldfish would get floaty all the time from gulping air and flakes at the same time. Then I switched to New Life Spectrum sinking pellets which was good for a few months... but last time, he got constipated for a week and kept sinking! My fish looked like he was in so much pain. After that incident, he was never able to eat sinking pellets without getting constipated, even when I reduced feedings to 1 pellet a day. When I did the switch to soilent green, he never floated/sank/constipated again. My other alternative would be making my own gel food, but that's suuuch a huge hassle. I'd rather just buy the lovely Soilent Green instead.
I'm happy so far with Repashy Soilent Green, although why they named it this is beyond me. Did they not see that movie? Our fish love it. I gave it 4 stars simply because I haven't been using it long enough to know long term how they will do on it. Easy to make but I have yet to find a good way to freeze the portions for easy use later.
This is a good product. Remember to get the ratios correct with H2O + powder. Just a warning, this stuff stinks like all get-out. Make sure to COVER IT UP in the microwave. And put on the exhaust fans. It stinks. I use it to feed my Ranchu Goldfish. It's a good thing to bring in to vary the diet, but man, it stinks. It's best to pre-mix, then bring to a boil, then spread to cool and solidify. I tried boiling water first, then mixing, but didn't get same gelatin results... I like it, but not sure I would order again.
