I took them home and placed them in a five gallon aquarium in a plastic mesh basket made from the plastic canvas used in embroidery' work. The basket is suspended an inch off the bottom so you can see with a flashlight when the eggs are spawned. The water was R.O. water made dark and acidic with peat moss. I would normally have conditioned the fish first but since they had to be quarantined anyway I thought I might as well try for a spawning. Also acidic water can ward off disease.
The next morning the fish laid some eggs, the males pressing the females against the artificial spawning strips I had placed in the basket, The next morning they spawned a bit more. That evening I removed the spawners to another tank. The first day's eggs were already hatching, which they do in thirty-six hours at eighty degrees. The tiny fry are like slivers of glass and lay on the bottom for two or three days before becoming free swimming. During this time I usually give the fry a clump of Java moss to hide in and partially shade the tank. I spawned them again a week later after feeding them on live glass worms. The first spawning has fifty or more fry and the second one has two hundred or more. The fry were fed infusoria for the first week and then microworms and baby brine shrimp. The fry are growing well and should be of saleable size in three to four months. Most Tetras are as easy to spawn as Danios so long as the water is very soft.
