Live food by fish

What live food does your fish actually need?

Search “live food for…” and you get a generic list. These pages are specific: a stage-by-stage feeding plan for each fish, the exact cultures to start, and the mistakes that starve fry or fatten adults.

By species

A betta (Siamese fighting fish) displaying in an aquarium

Live food for bettas

Wild bettas hunt insect larvae and tiny crustaceans all day, so live food is not a garnish for them — it is the closest thing to a natural diet.

Start with: Daphnia (Moina) · Grindal Worms

Neon tetras schooling in a planted aquarium

Live food for tetras

Tetras span the hardest feeding problem in the hobby — neon-sized fry that hatch almost microscopic — and one of the prettiest payoffs: adults in full colour on live food.

Start with: Vinegar Eels · Banana Worms

A marble angelfish (Pterophyllum scalare)

Live food for angelfish

Angelfish fry are bigger than tetra fry, which makes them one of the easier egg-layers to raise on cultured food: microworms bridge the first week, daphnia powers growth, and grindal worms condition the parents that started it all.

Start with: Microworms · Daphnia (Moina)

A male scarlet badis (Dario dario) showing breeding colour

Live food for scarlet badis

Scarlet badis are 2 cm predators in a nano fish body — and the internet’s most-asked badis question is some version of “why won’t it eat?” The usual answer is that the tank offers flakes to a fish that evolved to pick tiny living worms and crustaceans out of leaf litter, one at a time.

Start with: Microworms · Daphnia (Moina)

A Lake Eacham rainbowfish (Melanotaenia eachamensis) in an aquarium

Live food for rainbowfish

Rainbowfish fool breeders: the adults are hardy and greedy, but the fry hatch minuscule and grow slowly, spending their first weeks needing food barely bigger than infusoria.

Start with: Vinegar Eels · Banana Worms

A leopard danio (Danio rerio variety) close up in an aquarium

Live food for danios

Danios breed so readily that most keepers raise their first fry by accident — and lose most of them the same way, because free-swimming danio fry are tiny and the parents are fast.

Start with: Microworms · Daphnia (Moina)

A red dwarf gourami (Trichogaster lalius)

Live food for gouramis

Gouramis are surface hunters built around insects and larvae that fall on the water — which is why a feed of daphnia scattered at the surface gets a dwarf or pearl gourami hunting like it means it.

Start with: Daphnia (Moina) · Grindal Worms

A goldfish (Carassius auratus) close up

Live food for goldfish

Goldfish and daphnia are the oldest pairing in the hobby — Victorian goldfish keepers cultured “water fleas” in horse troughs for exactly the reasons modern keepers do: nothing keeps a goldfish’s digestion moving like daphnia, and nothing grows goldfish fry like a tub of it.

Start with: Daphnia (Moina)

A red cherry shrimp grazing on a leaf

Live food for freshwater shrimp

Shrimp are grazers and scavengers first — but watch a cherry shrimp colony hit a sprinkling of microworms and you will see the other half of their nature: they are opportunistic protein hunters that pick worms off one by one.

Start with: Microworms · Daphnia (Moina)

By fry stage

Tiny betta fry hanging in their bubble nest

Best food for betta fry

Betta fry are tiny — far smaller than guppy fry — and most first-week losses are fry starving next to food that is too big or does not move.

Start with: Vinegar Eels · Banana Worms · Microworms

Cardinal tetras schooling in a planted aquarium

Best food for tetra fry

Tetra fry are where breeders learn humility: eggs hatch in a day or two into fry so small they are mostly eye, and most losses happen before the fry are big enough for anything you can buy in a tub labelled “fry food”.

Start with: Vinegar Eels · Banana Worms · Microworms

A pair of corydoras with freshly laid eggs on the glass

Best food for corydoras fry

Corydoras fry simplify one thing and complicate another: they are bottom fish from their first free-swimming hour, so food must arrive on the floor — but they are also sturdier than most egg-layer fry and take microworms almost immediately.

Start with: Microworms · Banana Worms · Daphnia (Moina)

Zebra danio larvae under magnification, days after hatching

Best food for danio fry

Danio fry run on fast-forward: eggs hatch in two to three days, fry are free-swimming almost immediately, and a culture started “when I see fry” is a week late.

Start with: Microworms · Vinegar Eels · Daphnia (Moina)

A killifish snapping at live food at the surface

Best food for killifish fry

Killifish fry are born further along than most — many hatch able to take microworms within hours — but they grow at wildly uneven rates, and the fry tank’s real management problem is that last week’s fry eats this week’s.

Start with: Microworms · Vinegar Eels · Daphnia (Moina)
