African dwarf frogs are tiny, fully aquatic amphibians that make surprisingly rewarding pets. But feeding them can be tricky. They're carnivores with small mouths and poor eyesight, so getting their diet right takes a bit of know-how.

In this guide, I'll walk you through the best food for African dwarf frogs — from frozen bloodworms to live options — plus how often to feed them, how much, and what to avoid.

What Are African Dwarf Frogs?

African dwarf frogs (Hymenochirus spp.) are fully aquatic frogs native to central Africa. They stay small — usually under 1.5 inches long — and spend their entire lives underwater. Unlike many other frog species, they never leave the water.

They use a lateral line system (similar to fish) to detect movement and food. Their eyesight isn't great. So they rely heavily on smell and vibration to find meals.

This matters for feeding. Food that doesn't move or sink near them often goes unnoticed. That's why food placement and food type really do matter with this species.

African Dwarf Frog Diet in the Wild

In the wild, African dwarf frogs eat a variety of small invertebrates. Their natural diet includes:

• Tiny aquatic insects
• Small worms
• Brine shrimp
• Zooplankton
• Small crustaceans

They're opportunistic predators. They eat whatever fits in their mouths. Your job as a keeper is to replicate that variety at home — and that's easier than it sounds.

Best Food for African Dwarf Frogs

Here's a breakdown of the top food options, ranked from best to occasional-use.

1. Frozen Bloodworms (Top Staple)

Frozen bloodworms are the gold standard for African dwarf frog feeding. Most keepers and experts agree — these are the closest thing to a daily staple food you can offer.

Bloodworms are the larvae of midge flies. They're protein-rich and highly palatable. Your frogs will find them quickly because of their strong scent.

Tips for feeding frozen bloodworms:

• Thaw a small portion in a cup of tank water before feeding
• Use a pipette or turkey baster to drop food right in front of your frogs
• Remove uneaten portions after 20–30 minutes to keep water clean

Frozen bloodworms are far better than freeze-dried. The freeze-drying process strips moisture and some nutrients. Frozen ones retain both.

2. Live Blackworms (Best Overall)

Live blackworms are arguably the single best food you can offer your frogs. African dwarf frogs go absolutely wild for them.

Blackworms are live, wriggling, and they trigger your frog's natural hunting instinct immediately. They're also nutritionally dense — high in protein and essential fatty acids.

The downside? They require maintenance. You'll need to store them in a shallow tray with cool, clean water and rinse them daily. They die quickly if neglected. But for picky eaters or frogs that are refusing other foods, live blackworms almost always solve the problem right away.

3. Brine Shrimp (Live or Frozen)

Brine shrimp — live or frozen — are a great addition to the diet. They're small enough for even young frogs to eat with ease.

Live brine shrimp swim around, making them easy for frogs to detect via their lateral line. Frozen brine shrimp work well as an occasional supplement. Adult brine shrimp are more nutritious than nauplii (baby brine shrimp), but both are accepted readily.

If you keep a small brine shrimp hatchery, you'll have a constant supply of live food on hand for almost no cost.

4. Daphnia

Daphnia, also called water fleas, are tiny crustaceans that make excellent supplemental food. They're especially useful for froglets and juveniles.

Daphnia are lower in protein than bloodworms, so they shouldn't be your frog's only food. But they're high in fiber, which supports healthy digestion. Think of them as a nutritional side dish. Rotate them in every week or two.

5. Frozen Mysis Shrimp

Frozen mysis shrimp are popular for all kinds of aquatic animals. They're small, protein-rich, and widely available at fish stores and online.

Some frogs take to them right away; others ignore them. If your frog won't eat bloodworms for some reason, try mysis shrimp as an alternative. Many keepers use them as part of a rotation.

6. Sinking Pellet Foods (Use Carefully)

Some keepers use sinking pellets designed for aquatic frogs. These can work as a convenience food, but they're not ideal as a primary diet.

The issue is that frogs often don't recognize pellets as food until trained to do so. If your frog is used to live or frozen food, it may ignore pellets entirely. If you do use pellets, look for small, sinking formulas. Feed sparingly and always supplement with frozen or live foods.

7. Freeze-Dried Foods (Occasional Use Only)

Freeze-dried bloodworms and tubifex worms are widely sold in pet stores. They're convenient, but they have two real drawbacks:

1. They float, making them hard for bottom-dwelling frogs to reach
2. They're less nutritious than frozen options

If freeze-dried is all you have on hand, it'll work short-term. But don't rely on it long-term. Your frogs deserve better.

How Often Should You Feed African Dwarf Frogs?

African dwarf frogs should be fed every other day — about 3–4 times per week. They have small stomachs and slow metabolisms. Overfeeding is one of the most common mistakes keepers make. It leads to obesity and degrades water quality fast.

A good rule of thumb: feed what they can eat in 10–15 minutes, then remove the rest. That's it.

How to Actually Feed Your Frogs

African dwarf frogs have terrible eyesight. They hunt by smell and by detecting vibrations in the water. You can't just scatter food and hope for the best.

Best feeding technique:

1. Use a turkey baster or feeding pipette to deliver food directly in front of your frog
2. Gently wiggle the pipette as you release food — the movement helps frogs zero in on it
3. Use a small feeding dish or bowl in the same spot every time — frogs learn feeding routines quickly
4. Turn off the filter for 10–15 minutes during feeding so food doesn't get sucked away before your frogs find it

Consistency is key. Feed at the same time of day, in the same spot, with the same technique. Your frogs will start anticipating mealtimes.

Feeding African Dwarf Frogs in a Community Tank

If your frogs share a tank with fish, feeding gets considerably more challenging. Fish are faster and more aggressive eaters. They'll steal food before your frogs even know it's there.

Here's what works in a mixed tank:

• Target feed with a pipette — put food directly in front of each frog, one at a time
• Feed at night or with lights dimmed — African dwarf frogs are more active in low light
• Use a feeding dish so you can monitor who's actually eating
• Consider a feeding separator — briefly block off a small area of the tank during feeding time

If your frogs are consistently thin or lethargic in a community tank, underfeeding is very often the culprit. Don't assume they're getting enough just because you're putting food in the water.

What NOT to Feed African Dwarf Frogs

Some foods are harmful, too large, or just completely ineffective:

• Fish flakes — not nutritionally appropriate and usually ignored
• Crickets — they can't catch them, and dead crickets foul the water fast
• Large worms or earthworms — usually too big and may carry parasites from soil
• Waxworms — too large and too fatty; potential choking hazard
• Human food of any kind — absolutely no table scraps, ever

Stick to small, aquatic-appropriate, protein-rich foods that fit easily in their mouths.

Signs Your Frog Is Eating Well

A well-fed African dwarf frog will:

• Have a slightly rounded belly after meals
• Be active and swimming, especially in the evening
• Show interest when you approach the tank at feeding time
• Have smooth, healthy-looking skin

Signs of underfeeding:

• Visibly bony or sunken appearance
• Lethargy even during normally active hours
• Loss of color or dull, wrinkled skin
• Hiding more than usual

Signs of Overfeeding

Overfeeding is just as dangerous as underfeeding. Watch for:

• Bloated, distended belly (not just post-meal roundness)
• Cloudy water or rising ammonia levels
• Uneaten food sitting at the bottom of the tank
• Sluggish, unresponsive movement

If your tank water is consistently cloudy, cut back on feeding and do more frequent partial water changes. The two issues are directly linked.

Nutritional Variety and Supplements

Unlike reptiles, African dwarf frogs don't need calcium dusting or vitamin supplements in the same way. If you're already offering a varied diet — bloodworms, brine shrimp, blackworms, daphnia — they should get everything they need naturally.

That said, if you're relying heavily on a single food (like bloodworms only), you may want to occasionally gut-load your live foods or add a drop of aquatic vitamin supplement to the thawed food water once a week. It's not strictly necessary with a varied diet, but it's easy insurance.

Variety really is the key word. Rotate through 3–4 different food types each week if you can.

Water Quality and Feeding Discipline

Feeding directly impacts water quality. African dwarf frogs produce waste, and uneaten food rots fast. A few essential habits:

• Always remove uneaten food after 20–30 minutes — no exceptions
• Do partial water changes weekly — 25% is the standard
• Use a gentle sponge filter — strong currents stress your frogs and scatter food
• Test water parameters regularly — ammonia and nitrites should always read 0 ppm

A clean tank means a healthy, long-lived frog. Feeding discipline and water maintenance are inseparable.

Temperature, Behavior, and Feeding Changes

African dwarf frogs may eat less if tank temperature drops. The ideal water temperature is 72–78°F (22–26°C). If your frog suddenly refuses food, check the water temperature before assuming illness.

Frogs that are about to shed their skin may also temporarily stop eating. This is completely normal. Don't panic if your frog skips a meal or two — just keep offering food and monitor for other symptoms.
