FOODS FOR 'BABY' FISHER
Many newly hatched fries have very small mouths and consequently need very small food. Raising baby fish or fry is one of the most rewarding experiences in the aquarium hobby. However, their survival hinges on one critical factor: FOOD.
WHY FRY FOOD IS SO SPECIAL
Newly hatched fries have extremely small mouths and underdeveloped digestive systems. They require food that is:
𑇐 Microscopic in size
𑇐 Highly nutritious to support rapid growth
𑇐 Easily accessible within the water column
Feeding them inappropriate food is a leading cause of fry mortality. The options below are designed to give them the best start possible:
1) DIY Infusoria culture (The classic method): One of the best foods to use during the first few days is infusoria, which can be prepared by adding pieces of bruised lettuce leaves into a small bucket full of water. A small amount of aquarium water should be added to the bucket, after which the whole setup is incubated at 25 degrees centigrade for up to 48 hours.
The microscopic organism, protozoans, added to the tank water feed on the rotting lettuce leaf and multiply very rapidly. You can then use this to feed your fish by pouring a third of a pint twice a day for an average-sized aquarium.
2) Liquifry (The modern solution): A modern substitute for infusoria was developed by Dr.N.Carrington in 1952 with the trade name LIQUIFRY. This is made of minute food particles suspended in a liquid, which disperses rapidly through the breeding tank or hatchery and so cannot choke the delicate fry.
There are two main types, so choosing the right one is crucial:
I) Liquifry No.1: Formulated for egg-laying fish (e.g., Gourami, Angelfish, Cichlids).
II) Liquifry No.2: Formulated for live-bearing fish (e.g., Guppies, Platies, Mollies, Swordtails).
If you are not quick enough to lay your hands on formulated feeds, you could obtain water from green tanks or ponds, which are sure to contain either Paramecium, Euglena, or Chlamydomonas, all of which are excellent fry foods. Grindal worms-Enchytraeus bucholtzi- are similar to white worms and are very useful for feeding growing fry as they grow to only 4mm long. Cultures of grindal worms can be bought from selected pet shops.
Successfully raising fry is all about planning ahead. Before your fish even breed, decide which feeding method you'll use and have it ready. A well-fed fry will grow quickly and soon be large enough to eat crushed flakes and baby brine shrimp.
