Fact 6: Betta fish protection mechanism

When the male betta fish is in his aggressive stage he will puff himself out. During this puffing out he raises his gill covers and fins to make himself look larger than he is and therefore looks more impressive.

Some Asian countries breed them for fighting similar to the cocks in cockfighting. The betta fish used in this manner have shorter fins than the ones we normally see in our aquariums in the Western hemisphere.

Fact 8: Betta fish making bubbles

The betta fish seem to continually make funny bubbles on the top of the aquarium; this is just his way of making a nest. The male betta fish when in the wild makes bubble nests so that when the female happens by he does his tribal dance with his fins flashing to suitably impress her, when she is suitably so impressed she will spawn after which he will fertilize the eggs. Then being the perfect dad he will pick the eggs up in his mouth and place them tenderly into his bubble nest. That’s it; interlude over it was their ‘Brief Encounter’.

Fact 9: Betta fish eggs

For 2 days after the eggs have been laid and are safely deposited in the bubble-nest, the male looks after them totally, if any of the fry fall from the nest, he picks them up in his mouth and puts them back, so it is the male betta who cares for the eggs until and after they hatch, after which he may or may not choose to devour some of his young.

Fact 10: Betta fish feale aggression

You must remove the female as quickly as possible, because the male, just like the female black widow spider will turn on her male partner, the male betta will turn on the female betta.

BONUS: Tip on socializing Betta fish

The solitary position is the least stressful for the Betta fish. There are some no-gos when it comes to socializing fighting fish. In principle, any kind of additional stock is a stress factor for the fighting fish. If you still want to keep it in the community pool, the following rules must be observed urgently.

Socialization rules

  1. The by-fish must not be too hectic, as this stresses the fighting fish.
  2. In addition, keeping very small fish is problematic because some of them are viewed as prey.
  3. Due to the very long fins of the Betta splendens, it should not be kept together with fish that are plucked with rivers.
  4. Other territorial species (e.g. perch species) can lead to disputes.
  5. Last but not least, the fish associated with the betta should not have long fins, as these are sometimes viewed as competitors and are therefore forcibly driven away.

Some possible ways to socialize

  • peaceful labyrinth fish : e.g. threadfish
  • Catfish species : e.g. urinary, armored or antenna catfish
  • Snails : e.g. apple snails
  • larger types of shrimp:  e.g. Amanos
