Recommended Vivarium Size: At least 10 gallons per frog
 
Temperature: Range of 65 F to 80 F, but prefer temperatures in the low to mid 70s. Temperatures over 80 F are dangerous.
 
Humidity: Range of 70 – 100%, but can tolerate humidity down to 50% for short periods of time if the frogs have access to water. Low humidity levels, especially without access to water, can quickly be fatal.
 
Size: Adult female terribilis are larger, measuring approximately 2 inches. Male terribilis are a bit smaller, averaging about 1.75 inches at maturity. 
 
Life-Span: Bicolors are capable of living well over 20 years in captivity under ideal conditions, although a lifespan of 10 years is more common.
 
Feeding: Bicolors eat Drosphilia Hydei or Drosphilia Melanogaster fruit flies.  Bicolors will also eat pinhead crickets, springtails and isopods.  All feeder insects should be dusted with supplements.
 
Sexing: Phyllobates Terrbilis 'Bicolor' can be more difficult to determine sex. Male 'Bicolors' are easier to identify due to a loud call that can start between 8 and 10 months of age.  Male 'Bicolors' vocal sacks will also be more predominant due to the calling and stretching of the skin.  Females will tend to be larger than males.  Finn's Frog Farms sells unsexed juvenile frogs, least three months out of the water.  
 
Color/Pattern: 'Bicolors' will range in color from yellow to orange.  Some will have different colors on their legs.  When first coming out of the water the frogs will be much darker and have black markings on their feet.
 
Social Behavior: These frogs do well housed in groups up to sexual maturity, as long as enough space is provided. As they reach sexual maturity at 18-24 months of age, the social dynamic in a group of Phyllobates Terribilis 'Bicolor' may change.  Female 'Bicolors' may wrestle and eat each other's eggs.  It may be best to separate frogs into male/female pairs.  Finn's Frog Farm strongly recommends against housing different species/morphs of dart frogs. 
 
Breeding: Patricias are very simple and easy to breed. Like most Dendrobates tinctorius, Patricias are best bred in pairs. Generally, eggs are deposited on a smooth broad leaf, or on a petri dish under a cocohut. The eggs hatch into tadpoles, which then take 60-90 days to complete metamorphosis into miniature versions of the adults.
