Guppies: Best Tank Mates

what fish are compatible with guppies

Guppies are a very popular choice for fish enthusiasts, and for good reason. They are colourful, peaceful, and small, making them a great addition to any tank. They are also very community-friendly, but it is important to be careful when choosing their tank mates. Guppies are very small and fast, and have a mischievous nature, often nipping at the fins of other fish. They are also susceptible to being eaten by larger fish.

So, which fish are compatible with guppies? Cory catfish are a great option, as they are bottom dwellers that are peaceful and slow swimmers. They also help keep your tank clean by eating leftover food and algae. Swordtails are another good choice, as they are peaceful and have a beautiful appearance. Platies are a good option as they belong to the same family as guppies and have similar living conditions. Harlequin rasboras are small, gentle, and long-lived, making them a good companion for guppies. White cloud mountain minnows are colourful and small, and they prefer colder temperatures, so they are a good choice for guppies that prefer fancier breeds. Lastly, female bettas are a better option than male bettas as they have a less aggressive temperament.

Cory catfish are peaceful and can coexist with guppies

Cory catfish are an excellent choice for a community tank with guppies, as they are peaceful and won't harass other species. They are bottom dwellers, so they occupy a different space in the tank to guppies, which tend to swim in the top and middle sections. Cory catfish are also small, growing to about three inches long, so they won't take up too much space. They are also not picky eaters and will happily scavenge for leftover food at the bottom of the tank, acting as tank cleaners.

Cory catfish are social fish, so it's best to keep them in a group of six or more. They are also easy to care for and will suit a beginner tank. They are very peaceful cohabitants, and their slow swimming speed means they won't pose a threat to guppies. They are also great at picking up any leftover food in the tank, reducing the risk of bacteria or fungal infections in your guppies.

When it comes to water conditions, Cory catfish prefer a temperature range of 70 to 80ºF and a pH of between 6.0 to 8.0. They are sensitive to ammonia and nitrites, so it's important to ensure these elements are absent from the tank. They also prefer a sand substrate as their delicate fins and barbels can be damaged by a rough substrate, which can lead to infections.

Overall, Cory catfish are an excellent choice for a community tank with guppies, as they are peaceful, occupy a different space in the tank, and are easy to care for. They are also great at keeping the tank clean and won't harass other fish, making them ideal tank mates for guppies.

To minimize the chances of fights between guppies and dwarf gouramis, it is important to provide ample space in the tank, create hiding spots with plants and rocks, and maintain the right water temperature and pH level. Dwarf gouramis require at least 15-20 gallons of water, while guppies can thrive in a 10-gallon tank. The ideal temperature range for both species is between 74-82°F (23-28°C).

Mollies are active but peaceful and can be good companions for guppies

Mollies and guppies have very similar interests. They like to nibble on plants, breed, eat small amounts of food, and wiggle their bodies. They also have similar feeding requirements. They are omnivores and will eat the same types of food, including live food, cooked vegetables, and frozen foods like bloodworms. They also enjoy eating algae—mollies are bigger algae eaters than guppies.

Guppies are more peaceful than mollies, but males may become aggressive towards each other if there are too many males in the tank or if there is not enough space. Mollies are more likely to display aggressive behaviour if the ratio of males to females is too high or if the tank is too small. In both cases, the males may attack other males. Although mollies are rarely aggressive towards other species, they may nip at the fins of guppies or other species with colourful or flowing fins.

To keep guppies and mollies together, it is recommended to have a larger aquarium. A 20-25 gallon tank is sufficient to keep both guppies and mollies together. The bigger the tank, the more space for the fish to move around and be active. It is also important to have more females than males in the tank to prevent aggression. Both mollies and guppies tend to eat their fry, so it is recommended to separate them as soon as they give birth.

Harlequin rasboras are gentle and resilient and can be good tank mates for guppies

Harlequin rasboras are a great choice of tank mate for guppies. Both species are peaceful, docile, and lively, making them well-suited to sharing a tank. Guppies and harlequin rasboras are also adaptable to a range of water conditions, and they occupy the same area of the tank without any issues.

Harlequin rasboras are gentle and non-aggressive fish. They are unlikely to pose a threat to other fish in the tank, but their small size makes them susceptible to attacks from larger, more aggressive fish. Therefore, it is important to choose tank mates carefully. Guppies are a good match because they are also docile and non-aggressive, reducing the risk of conflict.

Harlequin rasboras are resilient and adaptable fish that can be kept in a large school or in smaller community tanks. They are native to Malaysia, Singapore, Sumatra, and Southern Thailand, but have become popular worldwide due to their small size and docile nature. They are shoaling fish, meaning they move around their environment in groups rather than alone. They are also timid and prefer to live in the middle to the lower levels of the tank.

When kept alone or in small groups, harlequin rasboras may become shy or reclusive, but they are still unlikely to exhibit aggressive behaviour. They are known for their peacefulness and are not fin nippers. This makes them a good choice for community tanks, as long as the tank is large enough to accommodate their preferred group size. Harlequin rasboras are happiest when kept in schools of at least 8-10 fish, and they can even be kept in larger schools if space allows.

Guppies are active and vibrant fish that are a favourite in the aquarium world. They come in a range of colours and varieties, adding a splash of colour to any tank. They are excellent community fish but require careful consideration when stocking a tank due to their small size and susceptibility to predation by larger fish. Guppies are also known to nip fins, so they should not be kept with long-finned fish.

In summary, harlequin rasboras and guppies are both gentle and resilient fish that can be good tank mates for each other. They have compatible temperaments and environmental needs, and their colourful appearances can create a stunning contrast in a community tank.
