What Do Guianacara Owroewefi Look Like?

Care for Guianacara owroewefi revolves around multiple aspects. From description and temperament to diet and habitat specifics, everything matters.

However, newbie fish enthusiasts should be aware of how to tell Guianacara Owroewfis apart from similar members of the Cichlid family. That’s where knowing their description can help.

Guianacara owroewefi is native to the Guyana and Suriname region. Appearance-wise, these fish have a well-developed dorsal and anal fin. The pectoral fin is short and almost translucent.

Their caudal fin is homocercal, which means the fin’s symmetrical in shape, and the vertebrae extend only a little into the upper lobe of the fin. Guianacara owroewefi size can range from 2 to 5.5 inches, or 5 to 14 cm, upon maturity.

They’re not precisely the most vivid member of cichlids in terms of color. Starting from the mouth, Guianacara are a light golden-brown that seems to luminesce under bright lights.

However, the lower half of their bodies, including the fins, have a bluish-gray tinge. The blue can be most clearly observed in their tail fins. You’ll also notice a black stripe near their eyes and an equally dark circular mark near the lateral line.

How to Care For Guianacara Owroewefi? The Two Most Important Aspects

Taking care of Guianacara owroewefi isn’t as tricky as many would think. Despite being a freshwater species, they’re pretty hardy and quite forgiving in terms of care and maintenance. Here are two of the most important factors when it comes to raising Owroewefis in aquariums.

– Diet

The Oworewefi fall somewhere in between bottom dwellers and mid-dwellers. They’re also riverine, which means they inhabit rivers and rely on them for a food source.

These fish aren’t averse to feeding on plants, algae, insect larvae, and other small fishes in the wild. In other words, Guianacara owroewefi are omnivores.

In captivity, fishkeepers can feed their pets an assortment of live, frozen, and dry foods. You can look into mosquito larvae, wingless fruit flies, or micro worms for live food sources.

Brine shrimp and bloodworms are excellent alternatives for frozen food. Finally, Mysis, daphnia, cichlid pellets, and flakes are perfect as dry food selections.

Young Owroewefi fish will require more frequent feedings because they’re still growing. However, once they’ve nearly mature at eight to nine months, you can reduce feedings to twice a day, depending on the fish.

– Habitat

An essential part of the Guianacara owroewefi growth care is learning about its natural habitat. Doing so will help you recreate its preferred setting in your aquarium, which will help your fish thrive and feel at home.

The Owroewefi inhabit various freshwater geographic locations but prefer warm waters with temperatures of 77 to 82 Fahrenheit. Aside from that, it’s best to include stones, roots, and driftwood in an aquarium meant to house these fishes. That’s because, in the wild, they’re primarily solitary cave dwellers that like keeping to themselves.

Try not to place any plants in a tank for this species because they don’t allow much digging in the substratum during the breeding period. It’s best to keep these fish in a pair, especially if you plan on extending your Owroewefi population.

The minimum aquarium size should be no less than 55 inches. However, if you’re planning on keeping your Guianacara owroewefi with other species, then an excellent standard rule to follow is to add a gallon of water per one inch of fish.

How Does Breeding Guianacara Owroewefi Work? What’s the Ideal Setting?

Breeding Guianacara owroewefi isn’t too tricky, provided you provide the fish the proper settings. Like many other Cichlids, the Owroewefi are egg-layers and nest-builders. That means the species will lay and fertilize the eggs outside the body.

It’s essential that the aquarium set up contains rocks small enough for the fish to utilize to build a cave. Adding peat moss to help the fish construct a suitable dwelling for laying eggs is a good idea too. Once that’s done, the female will lay eggs inside the cave, and the male will fertilize them. You’ll notice the male guarding the territory while the female takes care of the eggs during this time.

Once hatching occurs, the parent fish will move the larvae to a breeding pit instead. As nest builders, the species will continue to care for the fry anywhere from one to three months. After that, you can take over caring for the young fish by feeding them baby brine shrimps.

Also, note that over the three to eight years worth of Guianacara owroewefi lifespan, adults will breed about three to four times a year. If you don’t want your tank overrun with tiny Owroewefis, you might want to think about sticking with the males of the species.

What Are Suitable Tank Mates for Freshwater Cichlids?

If you’re planning on keeping your Guianacara owroewefi with other species, it’s essential to know what tank mates will get on best.

Owroewefis are primarily peaceful. Nonetheless, they’ve been known to get a bit aggressive during the mating season. If you’re planning on getting a male pair, this shouldn’t be too big a concern.

Besides that, they seem to get on well with other members of the Geophagus genus of Cichlids. These include Pearl Cichlids, Redhump Eartheaters, etc.

Guianacara owroewefi will also get along with medium to large-sized fishes, such as:

– Angelfish

Angelfish are native to the South American tropics and are riverine like the Owroewefi. You should know that Angelfish can grow to be quite big and are opportunistic eaters. That can spell trouble for the smaller fish in an aquarium. Fortunately, you can avoid such cannibalistic events by ensuring that all the fishes in your aquarium are well fed.

– Severum

If you want a well-behaved tank mate that also adds a little color to your fish tank, try opting for Severums. They’re typically harmless to other fish but can get a little aggressive when spawning. Severums prefer warm water temperatures and like plenty of room to swim.

Can Guianacara Owroewefi Fall Ill? Health Stats to Be Aware Of

There are no living creatures that aren’t prone to developing diseases, and the Guianacara owroewefi aren’t any different.

That’s why fish parents need to be aware of particular health concerns that may be common among their fishies. As far as Owroewefis are concerned, you won’t have much to worry about if you stick to their care routine.

Nonetheless, issues like inadequate lighting, water temperatures, or the development of certain bacteria can lead to problems such as:

– Fin Rot

Fin rot is a type of infection that targets the fins of a fish, though it can spread to other areas too. Often, fin rot will develop due to an existing wound on the fins that gets infected. Since fish eliminate in the same water they live in, it’s pretty easy for bacteria to thrive or infiltrate a fish’s body.

The best way to ensure your fish’s body is strong enough to fight the infection before it can damage its fins is to keep its environment healthy. For example, focus on cleaning the water at appropriate times to maintain quality. Being vigilant about the proper water temperature is also recommended.

– Hole in the head

It may sound hard to believe there’s any health condition called hole-in-the-head. But rest assured, the disease does exist, and Cichlids are especially vulnerable to it.

The condition kicks off as a small sore around the top of a fish’s head, around the eyes. The concerning bit is that, if left untreated, the sore can grow and penetrate the outer skin layer.

The disease is more common among fishes from aquariums with filters under the gravel, and it’s mostly connected to poor water quality. You can ensure the good health of your fish by sticking to a regular maintenance schedule for the tank.
