Andrew Marshall –
The rotifer cubes are easy to use and work well with my newborn fish. The small size makes them perfect for feeding without overfeeding. I’ve noticed better growth in my fry compared to previous feedings.
Matt Jones –
Great product for beginners. The cubes dissolve easily and the fish seem to enjoy them. I didn’t have to adjust my feeding schedule, which was a relief.

I’ve used this for my coral tank and it’s helped improve the zooplankton population. The nutritional content is clearly visible in the fish behavior and health.
