The microworm culture arrived quickly and the starter cup worked right away. My guppies started feeding within a day. The worms are active and the water stayed clear. Great for beginners.
Steven Rutherford –
I’ve tried several fry foods before, but this is the first one that actually gets the fry to eat. The live movement encourages feeding and the fry grow faster than with flakes.
Jacob Payne –
It took a few days to see the first batch of worms, but once they started, they were abundant. Works well with my betta and tetras. Slight delay in initial growth.

Perfect for a small nano tank. The worms are easy to maintain and don’t cloud the water. My shrimp are thriving now.

The package was sealed well and the culture was fresh. I used it with my guppy fry and they showed strong feeding behavior. A reliable starter for new aquariums.
