Fishrooms
A fishroom can be a 1 gallon jar, or an arrangement of tanks. Mine is a wall mounted rack of 5 shelves. 2 1/2 gallon tanks with the ends sticking out. A double 48" fluorescent fixture hangs over the front of the rack. Yes, those straps around the front of the tanks are "Earthquake" straps. You can see small containers for the "fry", and petri dishes for the eggs on top of the tanks, along with the killi-breeders best friend, THE FLASHLIGHT.
One of the things all killibreeders know is "there are no hard and fast rules", what works for one breeder may or may not work for another. There is only one constant "Killifish love to jump out of tanks". If you have the smallest opening in your tank, they will find it. One way I have been able to minimize the number of "suicides" (by jumping), is to use floating plants to cover the surface. This appears to make them secure (and maybe blocks their view of any opening) and I have less losses than others who don't.

Some of the tools of the trade. Small containers for the new hatch fry. Culture trays to incubate the eggs. I change the water regularly on the eggs during the two weeks of development. On the piece of paper there are brine shrimps eggs which are hatched out in a bubbling salt water solution to feed the little guys. A yarn mop is floated in the breeding tanks which is supposed to represent the roots of floating plants where most of the top spawners lay the eggs for me to collect and hatch out. The zip lock baggie contains moist peat moss with the eggs of bottom spawners. This moist peat is stored at room temperature for the appropriate period of time and then wetted to hatch the eggs out.

Once you get the Killifish to breed you need to collect the eggs, hatch them, and place them in an appropriate container. Now, what to feed them? Baby food of course! Micro worms, and other small foods are good. The best baby food is newly hatched brine shrimp. This is a brine shrimp hatchery. Aerated salt water, with a light on it to keep the temp around 80 degrees. And 24-48 hours later, Wa-La, baby brine shrimp. Disconnect the tube from the bottom, wait 5 minutes, point the tube into a brine shrimp net (gravity does the rest), and empty the contents of the brine shrimp net into a container with "tank water" and it's ready for feeding.
