DietIn wild they feed on mosquito larva, small water insects and in captivity they are fed on a variety of food such as frozen bloodworms, daphnia and pellets
Gender IdentificationIt is very easy to identify the gender, male have long body and fins and female are short bodied and have short fins
BehaviorAgressive in nature, Male and female show their aggressiveness by falring their gills
Compatibility Male siamese fighting fish is very teriitorial and it is advised to keep the males seperately. If you wanted to keep them in a community ensure there are fin peckers (eg. tiger barbs) and also avoid them with Guppies, killifish etc. Black tetras, Bloodfin tetras are one of the most comptaible fishes.
Ideal Tank ConditionsTo hold Siamese fighiting fish is strict NO. We recommend a minimum of 5 Gallon tank with good filtration, avoid heavy water flow.Would be good to give hiding spaces (plants or decors).Bright lighting is not recommended
Water ParametersIdeal pH is 6.8 to 7.4 and the water hardness should be less then 20 dGH. Ensure the water temprature is between 75 to 82 Degree Farrenheit or 24 to 28 Degree Celcisus
BreedingSiamese fighting fish are egg layers, the ideal age of a breeding pair is 1 year.Males blow the bubble nest in the water to indicate they are ready to spawn.Male fish will wrap its body around the female to expell the eggs.As soon as the eggs are expelled the male collects them and places them in the buble nest and in 36 to 40 hours you would see the fries. Within 2 to 3 days the fries would start swimming freely and it is time to remove the male from the tank. Baby brine shrim or Daphinia is the ideal food for the young fries. This whole week process would be an nerve wracking one for a hobbyist
Common DiseasesFinrot disease is the most common one and this could be avoided by keeping the tank clean and water parameters intact
Approximate CostThis depends on the country and the quality of the strain, in USA the average price is between 5 USD to 50 USD and in Asian countries it is available at 1/3 of the price of USA
What to look when buyingCarefully examine for any fin damages are cut in the body, look for any infections and see if the siamese fighting fish can spare well. Last but not least, pick the one which is active 🙂
