|You will need to keep your
breeding tank at an approximate temperature of 80°-82° F. I use a
50W heater in my 10 gallon tank.
Here is a heater I am considering purchasing :
Thermal Compact Heater
This heater attaches to the inside of your aquarium, you set the required
temperature and it keeps the tank at a constant level. Ceramic heater
core, pilot light and instant on and off switch ensures accuracy.
