So I have been working with a 20 gal tank for a few weeks. I updated the light fixture to CFL's. Divided the tank in three sections to put the females that are holding the babies in here until they are good to let out. The substrate is Sand and rocks that i had from the 100 gal main tank. Filter is a top fin 60. No heater yet because my temp in the house make the water temp stay at 76 to 78 degrees. Few anacharis and some fake plants. Well enough talking. Here a few pics. The second and third pic are the 2 females holding. The Red Zebra just dropped her new babies this morning.

The last pic are the young Red Zebras from the last time the girl was holding they are about 2 months old.
Enjoy.
