How To Make Young Baby Fish Fry Grow Fast
Young or newly born (hatched) fish (fry) can grow faster under the right conditions. We have noted in past experiments that access to food plays a big role in how quickly your fry will grow. Competition can make smaller fry go hungry while the larger fish consume more food and out-pace their siblings 2 to 1.
Sufficient food should be present, this may mean you need to feed the young up to 3 or 4 times per day. During the first week you could feed them up to 5-6 times per day. This time is essential in their growth and development. Helping them through this time will be a big help and get them a good start on the right track.
If it is possible, you will see better growth by splitting up a large batch of fry into two groups. If you have a group of larger fry and smaller, you can heard them onto different sides of the tank and install a divider. This will give the smaller fry more chances to eat.
Other factors outside of food and competition for food is heating and cleanliness. Cleanliness is mostly to make sure your fish fry are healthy and able to spend their time growing rather than battling infections. This may require 1-2 cleanings of fish food that went un-eaten from the bottom of the tank.
Providing adequate heat is also essential. Depending on the species of fish, the fish you are raising may do better in cooler or warmer waters. Generally, fish will move faster, grow faster and eat more in a warmer tank. Increasing the temperature in the tank even a couple of degrees can speed up their growth dramatically.
Make sure however when adjusting the temperature in your tank to keep it in the comfort range of your fish. Temperatures outside of their comfort range will lead to poor health, disease and possible death.
Lastly and probably the most important thing to remember is that if these are your pets, don't worry, take your time and enjoy them. Pressuring them to grow faster and increasing temperatures can likely lead to a shorter life span. If there is no rush to have your babies grow fast then it is recommended to keep their temperature within safe ranges, provide normal amounts of food and keep the tank clean to maintain a happy and healthy aquarium.
