Larval coelacanths feed on algae such as green algae, diatoms, nudibranchs, cyanobacteria, and protozoa, aquatic oligochaetes, branchiostomes, copepods, etc., as well as on concentrate feeds such as flour.

During the temporary breeding period, boiled egg yolk can be fed. Before adult fish culture, it is best to go through the seed breeding stage, cultivating the tiny juvenile fish into species with a body length of 5 to 10 centimeters, which can improve the survival rate. Fry cultivation method is the same as that of "four big fishes", first clean and disinfect the fish breeding pond, irrigate and fertilize the pond, cultivate plankton, and then release the fish seeds. The stocking density is 210,000 to 20,000 per 667 meters. The coelacanth feeds on benthic critters and organic debris in the substrate, and is best suited for mixing in ponds. The village side of the fertilized pond, aquatic insect larvae are more, every 667 meters 2 can be mixed with coelacanth species 100 to 200 tails. Thinner ponds can also be mixed with 50 to 100 tails. If other benthic fish (carp, crucian carp, etc.) in the pond are less, the stocking amount can also be increased. In this way, it does not affect the production of other cultured fish, but also can harvest dozens of kilograms more cochineal fish. Cochineal fish can also be mixed in fish breeding ponds and eel ponds. If the feed is sufficient, there are artificial compound feed feeding, can also consider the main culture.
