Scalaria: breeding at home conditions

It can be gratifying to breed Scalaria, popularly known as angelfish, in your personal aquarium. Because of their striking triangular form and flowing fins, these graceful fish are well-liked by aquarium enthusiasts due to their ease of maintenance. Understanding the unique requirements and behaviors of angelfish is essential for success if you’re thinking about incorporating them into your breeding efforts.

Though they are hardy fish, scalaria require the proper conditions to thrive. They do best in a tank that is kept up properly, has steady water conditions, and lots of hiding places. Having the proper fish tank size, pH levels, and temperature will help to make sure your fish are at ease and prepared for breeding. You can establish the perfect breeding environment in your own house with the correct setup.

Scalaria breeding calls for patience and meticulous attention to detail. These fish are well-known for their fascinating mating habits and nurturing behaviors. Through observing their mating habits and creating an appropriate habitat, you can see the whole process through from the first mating to the hatching of young. You will find the experience to be both extremely fulfilling and challenging, with the ultimate goal being the successful raising of healthy young fish.

Determining the sex of angelfish and forming pairs

Angelfish lack sexual dimorphism, meaning that the male and female species are essentially identical in appearance. It is impossible to tell the sex before puberty, and even then it can be very challenging. "He swam – it means he’s a male, she swam – it’s a female," is a joke among aquarists. Nonetheless, adult angelfish can typically have their sex determined; however, this is usually limited to individuals with a thorough understanding of fish anatomy. Let’s attempt to identify the indicators that indicate the sex of fish in this genus:

1. Mature males have a fatty hump on the forehead;
2. Males have a more convex pectoral keel;
3. If you look at the fish from the front, the lower part of its body resembles a wedge, and in the male this wedge is sharp, and in the female it is blunt;
4. A diagnostic feature is the genital papilla (in females it is called an ovipositor) – an outgrowth with an opening located between the anus and the anal fin, through which sexual products come out. In females it is larger and thicker, and in males, accordingly, it is thinner, sharper and directed backwards. These differences are especially clearly visible during spawning, as well as before and immediately after it;
5. The distance from the genital papilla to the anal fin in males is much smaller than in females. In fact, in males, the keel of the fin grows directly from the genital papilla, and since in striped angelfish the papilla is usually located at the base of the central stripe, it can be said that in males the anal fin starts from the base of the central stripe, and in females – behind it;

The longer dorsal fin of male angelfish sets them apart from females. Its back has dark transverse stripes that alternate with spaces in between. There are at least seven of these stripes on males, and no more than six on females.

However, in some cases—particularly in artificially bred forms with marble, golden, or albino coloring—it is impossible to accurately identify the sex of the fish based on these characteristics. In these situations, they attempt to ascertain the sex of the fish based on how they behave when they mate and start spawning in a shared aquarium. However, this isn’t always the case; sometimes, when males aren’t present, females take on this role in mating rituals and spawning, and same-sex couples even lay eggs (which, naturally, don’t get fertilized).

Here’s some guidance: if you’re looking to purchase an adult breeder fish, pick a fish that has already given birth to offspring or an individual with distinguishing characteristics and behavior. If a pair has formed, that is even better. If you plan to raise the breeders yourself, purchase 8–10 fry with long, wide fins. There will undoubtedly be individuals of both sexes among them, and when they eventually separate into pairs, you can choose which of them to use for additional breeding.

Angelfish are more likely to form pairs on their own, selecting a mate from a variety of individuals of the opposite sex. However, a fisherman can quickly select a couple from among the already-existing juveniles. When two angelfish of the same age and size are left together in an aquarium, they typically start to "build love." It is not advisable to split up already-married couples and choose new partners because fish are highly stressed out and don’t always form new relationships. The fish are kept together, swim with a goose, and the male starts to push the female into the aquarium’s corners to indicate that a couple has formed.

Growing producers and preparing for spawning

Fish kept under ideal conditions are those intended for future breeding. The water’s temperature is crucial for angelfish; it shouldn’t drop below 27°C. The quality of the feed is the second most crucial component; future producers must be fed frozen fish or live food such as bloodworms, tubifex, daphnia, etc. throughout their lives. Angelfish that are raised only on dry food typically have smaller bodies, paler coloring, and incapacity to reproduce.

Angelfish can spawn every two weeks under ideal circumstances, as long as the eggs are removed right away.

Before spawning, males and females must be housed together because, among other reasons, only in the presence of females do males prepare for spawning and the maturation of their reproductive products.

Raising the water temperature by 2°C and doing 10% weekly water changes three to four times a week are effective ways to encourage spawning. It is also preferable to add boiled or distilled water to the aquarium to lessen its hardness. Large-leaved plants belong in the aquarium, but you can also add a piece of ceramic or plastic tile for the angelfish to spawn on. Fish in this genus are typically allowed to spawn in a shared aquarium rather than being kept in a separate spawning tank.

When a pair is ready to breed, you can tell because of the round belly of the female and their altered behavior. The prospective parents start to clean their spawning area and jealously guard their territory.

Spawning

Spelling usually takes place in the evening and lasts for forty to an hour and a half. The male swims up behind the female to fertilize her eggs, which she lays on a previously cleaned surface usually in even rows. This process is repeated multiple times. There are between 700 and 800 eggs in all.

Incubator equipment and egg development

Angelfish, like other cichlids, take care of their offspring, but their parental instinct is not as strong, and this care usually lasts only 2-3 days. After spawning, the producers begin to protect the eggs from other fish in the aquarium, fan the eggs with their pectoral and dorsal fins, pick up the eggs that have fallen from the substrate and eat the whitened ones. In some cases, they take care of their offspring until the moment when they begin to feed themselves. It must be said that this care is very useful for the fry. But, unfortunately, such exemplary behavior is rather an exception to the rule, and usually the producers simply eat the eggs a few hours after spawning or with the onset of darkness. Therefore, if you do not want to risk finding out how caring parents your angelfish are, it is better to transfer the eggs to a separate aquarium 2-3 hours after spawning.

The following is how the caviar incubator is set up: water from an aquarium that holds manufacturers is partially filled into a small aquarium that holds five to ten liters. Distilled water is used to add the second half. After an hour, lower the substrate containing the caviare so that the caviar is washed by the sprayer’s flow but the air bubbles do not enter it. An incubator with a heater set to 30 °C is placed inside.

To prevent fungal caviar lesions, either use sera or methylene blue to produce an intensely blue color. One drop of mycopur is added to one liter of water. Little plants, like duckweed or rod, can be kept in an incubator to act as a biofilter and stop the aquarium’s nitrogen compound levels from rising too quickly when the fry start to grow rapidly. Furthermore, the thickets will support the growth of ciliates and Kolovrates, which will eventually provide food for fry. There should be constant lighting. You must leave the night light on at all times, even in the absence of any plants in the incubator.

Use a pipette to remove the whitened eggs the following day.

For any aquarium enthusiast, raising scalaria, or angelfish, at home can be a fulfilling and entertaining hobby. You can give these graceful fish a healthy habitat with a little planning and attention to detail. To begin with, make sure your tank is established and stable. Scalaria need a clean, well-balanced environment in order to flourish. Successful breeding will occur if the proper conditions are provided, such as suitable water temperature and quality.

It’s important to pair your Scalaria correctly. Your chances of a successful spawning will increase if you choose a compatible male and female. After they are paired, these fish frequently exhibit fascinating behaviors, like cleaning their spawning grounds and engaging in courtship displays. It can be fascinating to observe this process, which indicates that your fish are ready to mate.

It’s crucial to keep a close eye on the tank when your scalaria lay their eggs. Frequently, eggs are placed on level surfaces like leaves or tank ornaments. Both parents may fervently guard the eggs after the male fertilizes them. Be ready to handle any possible problems that may arise, like fungal infections or hostile actions from other tankmates. Making sure the fry have a secure place to grow will aid in their development into young, healthy animals.

In conclusion, raising scalaria indoors requires both patience and close attention to detail. The rewarding experience of raising angelfish from eggs to adults can be had by creating the ideal environment and keeping a close eye on your fish. Your aquarium will become even more lively and dynamic as a result of each successful breeding, which will also give you more experience and confidence.

If you are familiar with the basic requirements and conditions of Scalaria, or angelfish, aquarium enthusiasts can find breeding them at home to be a rewarding and manageable project. You can successfully raise these lovely fish by creating the ideal habitat with the ideal water parameters, offering a balanced diet, and making sure the breeding pair dynamics are correct. This post will walk you through the necessary actions and advice to ensure a seamless and pleasurable experience when breeding scalaria at home.
