Characteristics:
Great beginner frog
Bright yellow with black spots
Bold
Loud call
Large
Can be kept in groups when young
 
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 85 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 'Fine Spots' are larger, measuring approximately 1.25 inches. Male 'Fine Spots' are a bit smaller, averaging about an inche at maturity. 
 
Life-Span: Dendrobates leucomelas are capable of living well over 20 years in captivity under ideal conditions, although a lifespan of 10 years is more common.
 
Feeding: Fine Spots eat Drosphilia Hydei or Drosphilia Melanogaster fruit flies.  Adult Fine Spots will also eat pinhead crickets.  Young Fine Spots will eat springtails and isopods.  All feeder insects should be dusted with supplements.
 
Sexing: Dendrobates leucomelas 'Fine Spots' are not sexable until 10-12 months of age. Male 'Fine Spots' tend to be smaller than females, which often appear both longer and wider. Finn's Frog Farms sells unsexed juvenile frogs, least three months out of the water.  
 
Color/Pattern: Dendrobates leucomelas 'Fine Spots' can range from a bright yellow to an orange with black band and black spots.
 
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 10-12 months of age, the social dynamic in a group of Dendrobates leucomelas may change.  Females may each each other's eggs.  When breeding it may be better to keep them in pairs. Finn's Frog Farm strongly recommends against housing different species/morphs of dart frogs. 
 
Breeding: Fine spots tend to take longer to start breeding and can be a seasonal producers.  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.
