Hikari Micro Pellets Tropical Fish Food

Pellet size is the whole point

A fish can only eat what fits in its mouth, and the mouths of tetras, rasboras, barbs and similar nano fish are genuinely tiny. Standard tropical flake is often too large, and standard pellets almost always are.

Food that is too big gets mouthed and spat repeatedly, or ignored entirely, and then rots on the substrate. Micro pellets solve that, and it is a bigger deal than it sounds — a tank of small fish fed food they cannot properly eat is a tank with rising nitrate and hungry fish.

Semi-floating, and why that matters more than floating or sinking

Fish feed at different levels and a food that stays in the water column for a while reaches more of them.

A strictly floating food feeds only surface feeders and leaves bottom-dwelling corydoras and loaches with nothing. A fast-sinking food drops past mid-water schooling fish before they get a look in. A semi-floating pellet drifts down slowly, which gives everyone a chance.

If you keep bottom dwellers, they still need their own sinking food — a semi-floating pellet is a compromise, not a solution for them.

Overfeeding is the biggest mistake in fishkeeping

More tanks are damaged by too much food than by too little. Uneaten food breaks down into ammonia, ammonia feeds algae and stresses fish, and the fish that look permanently hungry are behaving normally — fish always look hungry.

The practical rules:

A tank with persistent algae and climbing nitrate is very often an overfeeding problem wearing a filter problem's clothes.

Colour enhancement, honestly

Colour-enhancing formulas contain carotenoids — astaxanthin and similar pigments — which fish deposit in their skin. The effect is real and it is the same mechanism that makes farmed salmon pink.

Two things it is not. It does not change a fish's genetics, so a washed-out fish becomes a better version of itself rather than a different fish. And it does not fix colour loss caused by stress, poor water quality or illness — a fish that has faded suddenly is telling you about its environment, not its diet.

Storage, because this is where food goes wrong

Fish food degrades, and vitamins go first. Vitamin C in particular breaks down within months of opening.

Variety is worth more than any single food

No dry food is a complete diet on its own for every species. Rotating two or three good staples, and adding frozen or live food — bloodworm, daphnia, brine shrimp — a couple of times a week, produces visibly better condition, colour and breeding behaviour.

Herbivorous species need vegetable matter specifically, and a blanched vegetable or an algae wafer is not optional for them.

Who should look elsewhere

If you keep bottom dwellers, they need a sinking food of their own alongside this. If you keep a herbivorous species, they need vegetable matter. And if your fish have faded, look at water parameters and stress before changing food.
