Archer fish are extremely difficult to breed in managed care; in fact, it is a rare occurrence. One reason is that it is impossible to determine the sex of these fish. When it does happen, though, these fish can spawn up to 3,000 eggs at once! The eggs float on the surface of the water and hatch after 12 hours.
Why do archerfish spit water?
The theory says that any stream of water has irregularities in thickness and surface tension – the tendency of water molecules to attract each other – which exaggerates the irregularities so that the stream breaks into droplets. The archerfish uses the way water ‘bunches’ and forms into droplets in tandem to make a powerful jet of spit.
Are angelfish the most alluring fish to keep?
Angelfish are some of the most alluring fish and most hobbyist can attest to this. However, choosing the ideal tank mate (s) becomes a daunting task. If you are not sure of which fish to introduce in the tank, then this article is for you.
Can angelfish live together in a tank?
Angelfish thrive in tanks of their own species especially in groups of 5-6. However, if you want to raise them in a community tank, you should introduce all species while they are still young. This way, angelfish will view them as potential tank mates.
How many spines does an archerfish have?
Banded archerfish have a deep laterally-compressed body with a flattened head and back. Their dorsal fins, set far back toward the rear of the fish, have four spines.

This species has a gold-colored body with dark blotches and they grow to about 4 inches in length. Because this species is are in the aquarium hobby, they tend to be fairly expensive.
Do fish use physics to kill their prey?
A species of fish that has a killer aim uses physics to hunt for its prey, according to scientists. Archerfish lurk under the surface of water before spitting to hit unsuspecting insects that have landed nearby, which when hit, plummet to their death to provide the fish with food.
What is the spit fall of archerfish?
In the graph below, this correction – the spit fall – is shown for different values of insect height. So, for example, when the insect is 10 centimeters high, the archerfish accounts for a spit fall of somewhere between 0 to 2 centimeters. When the insect is 30 centimeters high, this fall ranges from 2 to 15 centimeters.
How does an archerfish select its prey?
When an archerfish selects its prey, it rotates its eye so that the image of the prey falls on a particular portion of the eye in the ventral temporal periphery of the retina, and its lips just break the surface, squirting a jet of water at its victim. The archerfish does this by forming a small groove in the roof…
Why do archerfish squirt water from their mouth?
When the archerfish squirts a jet of water from its mouth, it ensures that the tail end of the jet is moving faster than the leading end. Imagine you’re standing in a queue and the people in the back start rushing forward.
Why don’t archerfish like water jetted water?
Similarly, as the water jet is squished by the fast moving water at the tail end, it would widen into a pancake. This isn’t good for the archerfish, because water that is more spread out will strike the insect with less pressure (force divided by area).
What is the average spit fall of an archerfish?
For example, if an insect is 10 centimetres above the surface of the water, the archerfish factors in a ‘spit fall’ of between zero and two centimetres, while is the insect is higher above the water at 30 centimetres, the ‘spit fall’ ranges from two to 15 centimetres.
Can angelfish live without a water filter?
Without a filter, the water in the aquarium will become toxic faster, which will lead to a compromise of the angelfish’s immune system. This can ultimately lead to diseases or even subsequent death. According to expert estimates, angelfish can survive a maximum of 12 hours in an aquarium without a water filter.
Why is my angelfish so territorial?
Like many fish species, your Angelfish is most likely to become feisty when feeding and during spawning, when the fish become very territorial. During the breeding season, you may need to remove the breeding pair of Angelfish to a separating spawning tank where they don’t feel threatened by their tank mates.
What kind of archer fish has 7 spots?
T. chatareus (common, seven-spot, or largescale archer): This Archer has seven bands or spots that are often broken into several blotches in a vertical row, which makes counting them a bit difficult. The scales are also larger, giving it a slightly lighter hue than the Banded Archer.
What is the difference between clouded archerfish and smallscale archerfish?
The Clouded Archerfish was originally believed to be identical to the Smallscale Archerfish (Toxotes microlepis), but because of structure and color differences, it was split into a new species. Clouded Archerfish are a true freshwater species that do not need to be kept in brackish water.
Where do clouded archerfish live?
Clouded Archerfish are found only in the rivers and estuaries of Myanmar from the lower Ayeyarwaddy to the Tenasserim Division, including the lower Sittaung and Salween rivers extending into Tenasserim Province, Myanmar. They may be present in Thailand (Ranong) but this has not been confirmed. Clouded Archerfish School (Toxotes blythii)
Do archer fish live in coral reefs?
Adult Archer fish are also likely to swim their way to explore coral reefs. This species is found in countries like Australia, Polynesia, Myanmar, Southeastern China, Thailand, the Philippines, and India. Archers prefer living in areas with thick plants hanging above the surface of the water.
