High temperatures--about 85 degrees Fahrenheit. Rams live in environments that are shallow and get very hot--they even seem to do well at 90 degrees. I'm not sure if the day/night cycle makes any difference, but you might try 14 to 16 hour daylight (makes a difference in angelfish). The usual equation, clean water, plenty of healthy food. ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com ------------------------------------------------------------------------- This is the apistogramma mailing list, apisto@majordomo.pobox.com.
