Live food for african dwarf frogs

African dwarf frogs are not really aquarium “fish food” customers at all — they are nearly blind, fully aquatic frogs that find food by smell, slowly, on the floor of the tank. In a community tank they are outcompeted by everything with fins. What transforms ADF keeping is worm food that stays alive on the substrate where a frog can blunder into it: blackworms and grindal worms, delivered to the frog.

The feeding plan

Stage	Feed this	Why it works
Staple worm feed (2–3× a week)	Live blackworms	The ADF classic — worms stay alive and waving in the gravel for hours, giving a slow, smell-hunting frog time to find dinner; fed from tongs or a dish, every worm is accounted for
In-stock rotation	Grindal worms, rinsed	Cultured clean in a box and the right size for a frog mouthful; sink straight to the floor where frogs feed
Light feeds & variety	Daphnia (moina)	Mostly a fish food, but frogs snap up moina they encounter at close range — good for froglets and small frogs
Froglets & small frogs	Young grindal worms and small daphnia, target-fed	Tiny frogs need tiny food placed precisely in front of them — portion size matters more than food size at this age

Practical tips

Feed the frog, not the tank: tongs, a pipette, or a small feeding dish on the substrate, always in the same spot. ADFs learn a feeding station remarkably fast.
Tap the glass or feed after lights-out routines: frogs hunt by smell and vibration, and feeding when fish are sleepy gets more food into frogs.
Watch bellies, not behaviour — a thin ADF in a community tank is usually being outcompeted, not ill. A separate feeding moment fixes it.

Watch out: Never rely on leftover fish food reaching an ADF in a community tank — it is the most common reason these frogs waste away in otherwise healthy aquariums. And keep them only with small, peaceful tankmates: big fish see a slow frog as a snack or a stress toy.

Common questions

What do African dwarf frogs eat?

Small meaty foods found by smell on the substrate: live blackworms are the staple of choice, with grindal worms as the cultured rotation and daphnia taken at close range. Most ADFs ignore floating dry food entirely.

Why is my African dwarf frog not eating?

Usually competition and eyesight, not appetite: the frog never found the food before the fish did. Target-feed worms with tongs or a pipette in the same spot each time and the frog will learn the routine within days.

Are blackworms good for African dwarf frogs?

They are widely considered the best ADF food — alive and moving on the tank floor for hours, which matches how a nearly blind frog hunts. Rinse them first and feed portions the frog finishes.
