Fish in the aquarium - types and attitude

Only the fish really enrich the aquarium and fill it with life. But not all species fit together and can be peacefully kept together in one tank. Some species like their roommates a little too much and eat and hunt them. Which species in which pool size ideally live together is shown here.

Compatibility and easy care

When buying fish you should pay attention to the compatibility of the species. Do not mix slow schools of fish with fast hunters. The calm fish will not stand the stress for long. In addition, in most cases, the tolerable pelvic inhabitants are also easy to care for, so ideal for beginners.

Fish that deserve their food

  • Antenna catfish - cleans especially the discs - easy to maintain but gets very big
  • Peckoltia compta Imperial Tiger - grinds algae from all surfaces - up to 12 cm tall - very expensive
  • Siamese algae eater - eats the algae - Swarm fish - up to 10 cm tall - about 5 euros per fish
  • African butterfly cichlid - eats snails and algae - up to 6 cm tall

Ideal fish for beginners

The ideal fish for a beginner sometimes offer a small problem because they are live-bearing fish. Once they feel really comfortable in the aquarium, it can quickly become tight. Especially the guppies show their enthusiasm in a veritable flood of offspring. It is not only space problems, but also problems due to inbreeding.

Of course, this can be avoided by keeping same-sex groups. Again, there is still a small risk, because the female fish may already be fertilized or even stored some sperm. Therefore, buy both the guppies and the platys only from reputable breeders who keep their animals in same-sex pools from the beginning.

Fish for small aquariums

Of course, small fish are also ideal for small aquariums. Nevertheless, in a nano-basin no fish should move in, but rather only shrimps and snails. Only from about 54 liters tank contents fish should be used at all.

While many catfish species, such as the antenna catfish can be much too large, the delta winged minnows is at most four inches tall. This little brown ground dweller is peaceful and prefers live food. But he also cleans up a bit on the ground, which makes him very popular when it comes to cleaning.

Jewelry or fighting fish are not for beginners

Fighting fish are usually not for beginners. They fight other species and attack each other. A rather harmless little specimen is the Crown Tail fighting fish or Betta Splendens, which is only four to five inches tall. A male of this particularly beautiful species can be associated with several females quite well with other peaceful species. From aquarium size of 60 centimeters, this calmer representative can even be held by a beginner.

Many types of fighting fish and ornamental fish fight each other until death. They seriously injure each other and eat each other's beautiful fins. Not only does this fish need a lot of experience, it also requires a large pool with a rich flora and hides.


Also with regard to feeding, you should take into account similar needs for the selected fish. For beginners are ideal species that are satisfied with dry flake food. Feeding with live food should always be done at about the same time. So think carefully in advance whether you can and want to always do that. After all, you do not want to subordinate your own life to the fish.
