Hardy Freshwater Fish for Beginners

Keeping fish both in the aquarium or ponds is a relaxing hobby even for the absolute beginner. With the sheer magnitude of fish choices available online and at the store, the beginners may have a hard time making choices. How big of a tank should I get? How many fish should I get? Which fish should I get?

If you are a beginner in fish hobby, one fish attributes that should to consider when evaluating fish as the good candidate to start out, is how hardy fish that you choose. The "hardy fish" means how some freshwater fish adapt better than other fish to variances in their environment. Here is a brief list of some other hardy fish for the beginner:

Guppy fish (Poecilia reticulate) is a species that has been domesticated for many decades by fish keepers and Guppies are a very hardy fish therefore well adapted to a life in aquariums and gives birth to live young every month. They are also quite inexpensive, have very sociable temperaments and are pretty. They are a somewhat schooling fish, and you will need to get a group of at least 4-6 guppies for them to do well. Don’t buy the most elaborate types of guppy since these are more sensitive than the more basic types.



Green Swordtails (Xiphophorus hellerii) are very handsome and are easy to recognize. The mail fish has a 'sword'; a long point at the very end of the tail fin. You can get Swordtails in a variety of colors, like vibrant orange and deep red. Swordtails can be slightly aggressive, and the males tend to fight each other for dominance. For this reason, you should purchase only one male and 2-3 females if you have a small aquarium. These fish breed every 28 days at 74°F. As with the Guppy, dense vegetation provides cover for developing fry. Another benefit of keeping this Green Swordtails is its tendency to consume algae.

Platy (Xiphophorus maculatus) belong to the specific name are distant cousins of the Swordtails, but are not aggressive. They also come in a large variety of colors. As with most livebearers, many color varieties have been commercially bred for the home aquarium. Platy fish should always be kept in schools.



Molly can be jet black, marbled or pure white. Mollies are quite peaceful by nature and are therefore great aquarium fish for beginners. Some of the males can get aggressive towards each other. This species is another livebearer that is gentle and is basically a vegetable eater. Like the Swordtail, the Molly will consume aquarium algae, keeping it in check. This species is lively and prefers schooling in small groups of four to six members. Only keep Mollies if you keep an aquarium white a pH of above 7 and preferable some salt in the water.

The Barb fish are also favorites among beginners. Barbs get their name from the short threadlike barbels that act as sensory organs on either side of their mouths and sometimes on their lips. Their vigor and agility in the midwater of the tank are important to the vitality of your aquarium. Many barbs, however, can harm smaller fish with ornate, veil-like fins. The Rosy Barb (Puntius conchonius) is a very peaceful species that adapts well to other community fish. The Tiger Barb (Puntius tetrazona) has a bi wilder disposition if introduced singly or as a pair, but if kept in schools of 8 or more, they leave the other fish alone. This species prefers warmer water in the range of 68 to 79 ° F. They are fast swimming schooling fish that brings life to the aquarium. Barbs are very easy to feed.

The Danios is another fast swimming group of fish. They are very easy to keep, breed and feed and are therefore ideal for beginners. As the very active schooling fish, Danios should be kept in groups of at least 7 or 8. The White Cloud Mountain Minnow (Tanichthys albonubes) is a very undemanding, active fish that should be kept in a group of 8 or more. These peaceful fish prefer cooler water and should only be kept in temperatures less than 72 degrees F.

There are of course numerous other "hardy fish" that would be equally great for the same and other beginners' requirements so do not stop with this simple list often. A good fish stores will look at his customers' wants and needs, and be ready to offer some solid suggestions on how to fill them.

They are ideal fish to put in a community tank and prefer to school with an odd number of at least 3 Diamond Tetras, making them an attractive addition to your nature aquarium.

To breed the Diamond Tetras, like breeding Platy fish, they should be separate a pair into a "breeding tank" with no lighting at first and then gradually increase it until spawning occurs. Water hardness should be less than 4 degrees and live food such as mosquito larvae are great inducers. Be sure to remove the adults after the eggs have been laid, as the adults will eat them. The eggs should hatch within 30 hours.

Arowana is a kind of "surface feeders" fish, indicated by the shape of the mouth. In nature they are swimming near the water surface to hunt for prey. Arowana can accept all types of feed for "carnivorous fish", but often they are so very fond of one type of feed only, and reject the other types. As an springer fish Arowana in the wild can catch insects perched on twig height of 1-2 meters from the water surface. So, the Arowana aquarium should be properly sealed.

Arowana is a powerful fish that can live up to half a century. High demand with limited natural availability causes exploitation in the nature be confined. CITES (Convention of International Trade in Endangered Species of Wild Flora and Fauna) stipulates that the Asian arowana fish as the fish that received the highest protection.

Platies Fish Care and Breeding

The Red Wag Platy is a colour variant of the Platies family (Xiphophorus maculates), one of the popular tropical fish which possibly a hybrid between two species and native to Mexico and Central America. They are predominantly red, but have black fins and lips. Like many other tropical fish, they have yellow and black eyes. Note that Platies can grow quite large in an aquarium - mine are about two inches long.

"Feeding Platies" is not difficult because Platy fish love to eat! They eat regular flake food for common tropical aquarium fish, as well as frozen food such as brine shrimp or bloodworm. During the feeding times, if they are pecking they also seem to suck algae off the vegetation in the tank.

Although it seems tasteful in algae, Platies inappropriately used as natural algae control for the aquarium because other behaviour of Platies which generate a lot of waste can actually cause more algae in the aquarium. I think, this is because they eat a lot more than other fish such as Neon Tetras or Tiger Hillstream Loaches.

About the resistance against fish diseases, Platies seem quite prone to the common aquarium ailments of white spot and various fungal infections, but they also respond well to treatment.

Platies are a live bearer, which are they giving birth to live young. Breeding Platy fish can be done en masse, but they have bad habits like eating their baby fish (fry) of its own, especially when the daily ration feed late or less. In fact other than the parent, there's more threat than any other aquarium inhabitants.

If you want to raise the fry you will need to move them to a breeding trap within the tank or moving them to a special fry tank. This is recommended to avoid the fry from predator such as Neon tetras, Aquarium Shrimps or other fish which may eat them. Therefore, in order to obtain maximum results, "Platies breeding" should be coupled with efforts to protect the baby fish (fry).
