The presence of infusoria is masi easily detected during feeding, il the fry converges at the point where the liquid is dripped into the water. Optically infusoria only become visible at 25x to 50x  agnification. lf tao much infusoria are given, a mucous film will develop on the water surface during the 3'' day. lnfusoria cannot develop il the water used lor starting the batch contains residues of chiarine or medicines.

Application:

Direct application: Alter the fry have hatched put 6-12 grains of Protogen into aquarium depending on number of baby fish. Double this amount on the second day. Feed again as required until large food
