Maria Lambert –
My discus fish have gained weight and their colours have become brighter since switching to this food. The granules sink well and the fish seem more active. No fish have shown signs of illness, which I attribute to the probiotic support.
Keith Quinn –
The food is easy to feed and the fish eat it readily. I noticed a cleaner tank over time, which suggests less waste. The colour improvement is subtle but noticeable after a few weeks.
Emily Piper –
I’ve tried several fish foods, but this one stands out. The probiotic component seems to improve my fish’s digestion and overall health. It’s a reliable daily feed with no unpleasant odour.
