Feeding habits of opal betta fish

Opal betta fish are naturally carnivores but can accept a variety of food in aquarium conditions if trained well. They are famous for eating like crazy and will never say no to food. So, it is their owner’s responsibility to feed them moderately.

It is advised to include lots of proteins in their diet, so do it by feeding live food, freeze-dried and frozen food. But make sure you are not giving it daily. It should be given as a special treat to them. If feeding frozen or freeze-dried food, defrost it before feeding your fish.

You can also feed your opal betta fish veggies or plant-based food, but bettas don’t like to eat plant matter. It can be given occasionally but not regularly.

Overfeeding is a common problem among bettas, so it is very important to feed betta fish moderately and the leftovers should be removed every day using a gravel siphon to avoid the accumulation of leftovers in the substrate. 

Leftovers can increase the levels of ammonia in the tank and will change the water chemistry. 

Feeding frequency- Feed adult bettas twice a day and young or juvenile opal bettas thrice a day.

Behavior of opal betta fish

Breeding of opal betta fish

To breed an opal betta fish you have to maintain a breeding tank exactly like their main tank with lots of plant covers, heater, and other accessories you add to the main tank.

Keep male and female betta in a breeding tank and let them know each other. During this period don’t disturb them, as it can distract them and breeding won’t happen.

The Male will make a bubble nest and wait for the female to release eggs, this whole process will get over in three days and babies will come after three days. 

Male betta will look after the fry until they become free swimming. Female bettas don’t show parental care and look more aggressive during breeding and post-breeding. It would be best to remove female bettas from the breeding tank to the main tank, as female bettas can end up eating baby bettas if they are under stress.

Feed betta fry healthy and nutritious food for their growth and development and separate them when they become free swimming.
