Dart Den

Is the entire Genus considered a "Highland" species - preferring cooler temps, than say, pumilio ?

How about Santa Isabel ?

What are your day and night temperatures ?

For my SI's the daytime highs are around 74, nighttime lows are around 62 (sometimes a few degrees cooler). If the temp goes above 75 they tend to hide towards the bottom of the tank. They are most active when the temp is right around 70.
