My guppies have grown stronger and their colors have become more vibrant since switching to this food. The water looks cleaner too, and they seem more active. Easy to mix and feed.
Peter Jones –
Good for small fish. The fish eat it willingly and seem healthier. I noticed less fish waste in the tank after a few weeks. A solid choice for beginners.
Dominic Miller –
The granules dissolve well and the fish show better appetite. The astaxanthin gives a nice red tint to the fish. I’ve used it for two months and no signs of illness.
Rachel Watson –
Works well for my 4 cm tetras. The tank water stays clearer and the fish grow steadily. Slightly more expensive but worth it for the health benefits.
Claire White –
My fish have not gotten sick in over a month. The coloration is much better than before. I appreciate the natural ingredients and the ease of use.
