What fish live in tropical waters?

Families of freshwater tropical fish include characins (e.g., tetras: Gymnocorymbus spp., Hemigrammus spp., Hyphessobrycon spp., Paracheirodon spp., Moenkhausia sp.), cyprinids (barbs: Barbus spp.), catfish (e.g., Corydoras spp., Pimelodus spp.), killifish (e.g., Aphyosemion spp., Fundulopanchax spp.), rainbowfishes ( …

Why do tropical fish not survive in freshwater?

Saltwater fish can’t survive in freshwater because their bodies are highly concentrated of salt solution (too much for freshwater). The water would flow into their body until all their cells accumulate so much water that they bloat and die eventually.

What adaptations do tropical fish have?

Adaptations for Water

  • Fish have gills that allow them to “breathe” oxygen in water.
  • Fish have a stream-lined body.
  • Most fish have several fins for swimming.
  • Fish have a system of muscles for movement.
  • Most fish have a swim bladder.

What is the difference between freshwater and tropical fish?

Although both types contain fish from tropical (warm) climates, the freshwater fish are from the rivers in these climates and so live in fresh (unsalted) water. Tropical marine fish are from the sea in these areas, and therefore live in saltwater.

Where do tropical fishes live?

Tropical fish are generally those fish found in aquatic tropical environments around the world. Fishkeepers often keep tropical fish in freshwater and saltwater aquariums.

Do fish get thirsty?

The answer is still no; as they live in water they probably don’t take it in as a conscious response to seek out and drink water. Thirst is usually defined as a need or desire to drink water. It is unlikely that fish are responding to such a driving force.

Why do most fish live in saltwater?

Here is his answer. The reason some fish normally live in freshwater and others live in seawater is that one or the other environment provides them with opportunities that have traditionally contributed to their survival. An obvious difference between the two habitats is salt concentration.

How did fish adapt to living in water?

Fish have adapted to their environment through the evolution of gills, swim bladders and fins. Gills allow fish to absorb oxygen from the water, swim bladders allow fish to maintain an appropriate level of buoyancy and fins allow the fish to move through the water.

What do fish need to survive?

Like other living creatures, fish must meet certain basic needs for survival. Water, food and shelter are among the most important requirements: Water: Fish not only live in water, but they get oxygen from water. They breathe by taking water into their mouths and forcing it out through gill passages.

Can tropical fish live in cold water?

Tropical fish, for example, do best between 75° and 80°F, goldfish and other “cold-water” species prefer temperatures below 70°F, and temperate fish can be found in habitats that overlap tropical and cold-water realms. The problem is, as water warms up it holds less oxygen, which further stresses the fish.

Why are tropical fish kept in fresh water?

Freshwater tropical fish are more commonly kept than saltwater tropical fish due to the common availability of fresh water sources, such as tap water, whereas salt water is not commonly available and has to be recreated by using fresh water with sea salt additions. Salt water has to be monitored to maintain…

Where does saltwater tropical fish come from?

Saltwater tropical fish. Marine fish that are sold as tropical fish are generally sourced from the wild, usually from the coral reefs around the world. This is because only a few species of marine fish have been successfully bred in captivity with any regularity.

Why can saltwater fish live in freshwater and vice versa?

The water would flow into their body until all their cells accumulate so much water that they bloat and die eventually. On the other hand, freshwater fish can’t survive in the ocean or saltwater because the seawater is too salty for them. The water inside their bodies would flow out their cells, and they wiil die of dehydration.

Can a tropical fish be a wild fish?

Aquarium fish. Tropical fish may include wild-caught specimens, individuals born in captivity including lines selectively bred for special physical features, such as long fins, or particular colorations, such as albino. Some fish may be hybrids of more than one species.
