8 Best Tank Mates for Fire-Bellied Toads (Compatibility Guide)

Fire-bellied toad on a big rock

The fire-bellied toad is a fascinating creature part of the bombinatorid family. They are a group of six different species of small toads. These toads have an interesting pattern with attractive colors. They are known for being peaceful but do have certain risks as tank mates. The fire-bellied toad is known to secrete a toxin through their skin called bombesin. This toxin is isolated from the skin of the toad and binds to bombesin receptors. This makes them dangerous to humans and they should be handled with care.

Since the fire-bellied toad releases toxins if they feel threatened by other creatures in their presence, it is difficult to keep them with other types of amphibians and fish. It is not uncommon for the toxins to build up and cause harm to fellow tank mates. With strict procedures in place, you may be able to keep your toad with some friends.

The 8 Best Tank Mates for Fire-Bellied Toads

1. White Cloud Minnows (Tanichthys albonubes) – Most Compatible

Size: 1 inch
Diet: Omnivore
Minimum Tank Size: 10 gallons
Care Level: Beginner-friendly
Temperament: Community (Should be kept in groups of 6)

White cloud minnows are an interesting shoaling fish. They have attractive colors and are quite hardy which allows them to tolerate living with a fire-bellied toad. White clouds seem to withstand the slow-released toxins from the toad if frequent water changes are done. These two species rarely seem to interact with each other and are peaceful.

2. Mystery Snails (Pomacea bridgesii) – Best for Small Tanks

Size: 3 inches
Diet: Omnivore
Minimum Tank Size:
Care Level: Beginner-friendly
Temperament: Peaceful

Another classic favorite tank mate for the fire-bellied toad is mystery snails. These are adaptive snails that grow large and come in a variety of attractive colors. They do not eat live plants but will eat algae, debris, and decaying plants. The toxins may begin to irritate the snail if it reaches high levels. This is a sign that a water change must be done to dilute the toxins.

3. Fancy Guppies (Poecilia reticulata)

Size: 1-2 inches
Diet: Omnivore
Minimum Tank Size: 5 gallons
Care Level: Beginner-friendly
Temperament: Community (Should be kept in groups of 5)

These are colorful and playful shoaling fish that look stunning in a fire-bellied toad enclosure. They are a little more delicate than other fish and water chemistry is an important part of keeping them healthy. It is best to get either a male or female group since mixing the two genders will result in mass breeding and guppies can quickly overpopulate a tank.

4. Chinese Fire-Bellied Newts (Cynops)

Size: 3 – 4 inches
Diet: Omnivore
Minimum Tank Size: 20 gallons
Care Level: Intermediate
Temperament: Peaceful

The Chinese fire-bellied newt has a similar name to the fire-bellied toad. Both are amphibians and have similar habitats. They get along well together and enjoy slow-moving bodies of water. This makes it a great idea to add a small stream in the enclosure. Keep in mind they have different diets and should be fed separately.

5. Common Goldfish (Carassius auratus)

Size: 8 – 12 inches
Diet: Omnivore
Minimum Tank Size: 55 gallons
Care Level: Beginner-friendly
Temperament: Playful (Should be kept in pairs)

Feeder goldfish can make a great addition to the body of water in the fire-bellied toad’s enclosure. Goldfish are hardy and can tolerate mild levels of toxins in the water. The goldfish should be dewormed and treated for parasites before being placed in the toad’s enclosure. Since goldfish get large, they are only suitable for very large fire-belly toad enclosures.

6. Green Anoles (Anolis carolinensis)

Size: 5 – 6 inches
Diet: Carnivore
Minimum Tank Size: 20 gallons
Care Level: Experienced keepers only
Temperament: Peaceful

The anole is a tree-dwelling species native to the southeastern United States. They look great with fire-bellied toads and make quite the fascinating pair. However, anoles require a more experienced owner who can provide the right conditions for them even with a tank mate.

7. Diurnal Geckos (Phelsuma)

Size: 8 – 10 inches
Diet: Omnivore
Minimum Tank Size: 29 gallons
Care Level: Intermediate
Temperament: Peaceful

This is known as the giant day gecko. They are native as a species to Madagascar and have a bright green coloration with orange on the head. Hence the name, these are some of the gecko species that are most active during the day. This makes them beneficial to live with fire-bellied toads and you do not need special night lights to see them.

8. Tree Frogs (Hylidae)

Size: 2 – 5 inches
Diet: Insectivore
Minimum Tank Size: 20 gallons
Care Level: Intermediate
Temperament: Peaceful and inquisitive

These are small amphibians that do great with toads. They have the same setup and both the tree frog and fire-bellied toad enjoy spending the majority of their time in branches and hiding amongst leaves. They have similar moisture requirements which makes them excellent for an enclosure with a body of water.

What Makes a Good Tank Mate for Fire-Bellied Toads?

The best tank mate for a fire-belly toad would be another amphibian. This is because they seem to get along quite well. Fish are another good tank mate but can easily be killed by the toxins leaching into the water. Most toad owners will keep a mixture of amphibians and fish with their toad. This is because the fish live in the water column, whereas the amphibians and reptiles will hang around the vegetation and occasionally take a swim to rehydrate.

Where Do Fire-Bellied Toads Prefer to Live in the Enclosure?

The fire-bellied toad prefers to live near the bottom of the enclosure. They enjoy hiding in the moist substrate and taking cover under a nice leaf. The bottom of the enclosure seems to hold the most moisture and this prevents the frog from drying out. Fire-bellied toads will sometimes climb towards the middle of the enclosure depending on where they prefer to eat.

Water Parameters

Fire-belly toads are semi-aquatic and live both on land and in the water. They grow up in the water as a tadpole and eventually adapt to living above the surface, but they still make visits to small pools in their enclosure, so it is important to ensure the water quality is good. The ammonia and nitrite should be between 0ppm to 0.25ppm (parts per million) and nitrate should be kept below 30ppm. The water should be dechlorinated before being placed in the enclosure.


Fire-bellied toads are not very big. They get to an adult size of 2 inches (6 centimeters). Since they are so small, they can do well in smaller enclosures. 20 gallons is an accepted minimum for the fire-bellied toad, but the size should be increased if you plan to add in-tank mates.

Aggressive Behaviors

Fire-bellied toads are not aggressive, but they can become feisty during feeding time. Like a typical toad, they sit around and wait for food. So, when feeding time does come around, they will make sure they are the first to get it. This can be a problem if they are kept with tank mates as they will try to steal their food.
