|Egg||Up to 60 hours from spawning||At 80F eggs will hatch at 48 hours. Hatch time can be shortened slightly with increased temperatures or lengthened by cooler temperatures. Interestingly, all eggs seem to hatch within a fairly narrow timeframe.|
|Wiggler||From hatch to free swimming||Typically ends 7 days from spawning. The duration in this growth stage is determined by water temperatures. Higher temperatures will lead to faster development; cooler temperaturs to slow development. Parent raised fry may hang close to a surface for an extra day or two as the parents will attempt to return them to the selected surface.|
|Fry||From free swimming until they take on the angel appearance||As the fry grow they will change from their elongated shape to the elongated dorsal and anal fin that give them their appearance. This stage typically lasts about 2 weeks from free swimming or 3 weeks from spawning
Some strains are known to take longer to reach the next stage. For example, Double Dark Blacks can take up to 4 weeks, twice the time, to reach the next stage. Other factors include water conditions, overcrowding, quality of food, etc
|Juvenile||True angelfish shape with elongated fins and a flattened body||Referred to by comparing to American coins (dime, nickel, quarter, half dollar or silver dollar)|
|Adult||Mature Breeders||This stage is reached anywhere from 6 months up to a year. Typically angels mature at 9 to 12 months.|
Fish age can be from the time the eggs were spawned or from the time the fry start free swimming. Typically, one 1 week separates the two, but it can make a difference when attempting to compare growth rates. Interestingly, most refer to species that begin life as an egg are aged from the hatching date typically. Angelfish fry/juveniles, however, are aged from the spawning date.
