Why is baby betta fish care important?

Baby bettas are very delicate and need special care and attention than adult bettas.This is a critical stage that will decide how they grow as an adult.They will die off easily,if they are not cared for properly.

How many baby betta fish should you start with as a newcomer?

As a newcomer you can start with 2 baby bettas, but make sure you are not getting only males.You can get 2 female baby bettas and 1 male baby betta or two female baby bettas.

Male bettas become territorial and start fighting with each other for space and resources.Females are occasionally aggressive but they can co-exist together.

Initially keep them in separate tanks.Baby bettas will be around six to seven months old when offered for sale in pet shops.

In my opinion don’t purchase them from pet stores,try to get them from right breeders who are aware of their genetics and breeding.

They thrive well in clean tanks, the type of diet you are giving them and the amount of care you are providing them from egg stage to maturity stage.

Light intensity for baby betta fish

Artificial lighting like LED bulbs/aquarium lighting  

  • Mild sunlight

Substrate/Decoration for baby betta fish

Baby bettas don’t need substrates like adult bettas, because they spend their time in the middle and upper regions of the tank.

If you want you can add small gravels or fine sand grains or mixtures of both will also work.It is totally up to you as they don’t interact with the bottom surface.

Avoid using large rock works,because they might get trapped in them and die.Avoid sharp and edgy decors in the tank, this can hurt their beautiful flowing tails.Clean all decors before adding them to the aquarium.

Water parameters for baby betta fish

  • Baby bettas need clean,calm and dechlorinated water for their growth.
  • Filtration system-Sponge filters,they provide mechanical filtration without hurting baby bettas.
  • Don’t use power filters or strong currents filters because these filters might hurt them or even get sucked up in such strong filters.
  • Baby bettas tend to eat a lot so they require frequent water changes.And you really don’t  need a filter,if water is getting changed frequently.
  • Water changes should be done twice a week and siphon the dirty water from the bottom using vacuum and replace that with dechlorinated water at the similar temperatures.
  • Keep ammonia and nitrate levels below 0.2, if it goes upto 1 then it indicates ammonia pollution.

Temperature for baby betta fish

Temperature plays a key role in the aquarium settings, as it is responsible for the fish metabolism.Maintaining the stable temperature in the aquarium environment will keep your bettas active and healthy.

A sudden drop or increase in the temperature could make them inactive and weak. Already baby bettas have weak immune systems, so kindly maintain stable temperatures for their survival.

  • Baby bettas need  properly heated water/warm water.
  • Their digestive system will not function properly and they won’t be able to eat nutritious food unless their temperature is within the range,i.e ideal temperature – 76F-84F.
  • Lower temperatures can affect their health.
  • Temperature fluctuations can have negative impacts on their health.
  • They need small adjustable heaters in their tanks as they cannot thrive well in extreme cold or hot temperatures.

Tank plants for baby betta fish

  • Almond leaves for maintaining the pH
  • Live plants- for oxygenation and hiding
  • Silk plants – hiding spots

Baby bettas should not be kept with tank mates at this tender age.Keeping them with tank mates can stress them and can reduce their lifespan.keep them alone until they reach adulthood.

Baby betta fish diet and feeding requirements

Baby bettas accept a diverse variety of food and a mixture of live food  and plenty of protein diets will keep them healthy.

Feed them smaller amounts several times a day but make sure you are not overfeeding them,it can hurt their digestive system.In case of betta fry start feeding them once they start swimming.

They can be hand fed or with the help of eye droppers.

  • Infusoria,a liquid based food for betta fry.It can be given in small amounts several times a day.It is commercially available.
