Frequently asked questions
How much flake food should I feed?
Follow the two-minute rule: feed only what your fish finish in about two minutes, once or twice a day. Uneaten flakes sink, rot and spike your water parameters, so it's always safer to feed a little less than a little too much.
Are flakes or pellets better for tropical fish?
Neither is strictly better — it's about the fish. Flakes suit small surface and mid-water community fish like tetras and guppies, while pellets suit larger or bottom-oriented fish. Many keepers rotate both, plus frozen foods, for a varied diet.
Do fish flakes really improve colour?
Foods with natural pigment sources such as spirulina, krill and astaxanthin can genuinely deepen reds and yellows over weeks of regular feeding. It's gradual, not overnight, and works best alongside good water quality and low stress.
