Duration female 2 (yr):1.0 Size female 2 (mm): 64
Broodstock notes: Broodstock belong to Steve Tyree (refer to report CENLOR01.htm)
Physical differences:Male is larger, females have expanded abdomens when ready to spawn
Adult diet:Spirulina flakes, Formula 1 & 2®, live Artemia nauplii, and tank foraging
Pre-spawning activity: not indicated
Time spawning began:PM twilight Area spawning occurred: open area above mini-reef
Frequency of spawning: every other night Egg description:hatched when received
Approximate quantity:~50 Size:hatched when received
Egg changes / development:transparent larvae form inside egg, short incubation period
Incubation period:n/a Time hatching occurred:
Size of hatching larvae:1 - 2 mm Yolk sac present?:yes
Newly hatched appearance: Transparent, nearly "invisible" slivers with eye spots and yolks.
Transfer / removal method: Eggs were collected with a bowl and transferred in a 5 gallon poly bucket by car from the Los Angeles area to Sacramento (~ 6 hour trip). Larvae were then removed using a small beaker and placed into the rearing vessel.
Spawning tank size (liter):670 Sides of tank covered?Yes
Lighting & photoperiod:3 - 175 watt MH (13 hours). 2 - 140 watt actinic (13 hour) twilight (2 hour)
Filtration:Live rock, skimmer, trickle filter, mechanical / chemical
Additives and dosages:Liquid Gold®, Reef Plus®, Reef Calcium®, KSM®, VitaChem®, Kalkwasser and Super Iodine®
Water temperature (F): 79 Specific gravity: 1.022 pH: 8.3 Nitrate: < 0.25
Fry development / changes:Black pigment on sides at day 4, extending on day 5 - 6. Swimming head "down" in water column until day 7 - 8. Rapid darting motions to feed.
First food offered: Greenwater with Acartia and/or Tisbe sp.
Second food offered:rotifers on day 2
Survival 1st week(%):50% 2nd week:15% 3rd week: 0%
Development description:Active until day 11, none remaining on day 12
Rearing tank size (liter)9.5 Sides of tank covered? Yes, black
Lighting & photoperiod:Fluorescent cool white 40 watt (13 hours) from side
Filtration:None, mild aeration (slow bubbling). 10% water changes daily
Additives and dosages:none
Water temperature (F): 75 - 79 Specific gravity: 1.021 pH: 8.26 Nitrate: <1 ppm
Comments:Ammonia 0.786 ppm at highest level (measured with ion specific probe [Orion]). Feeding density possibly not great enough. Copepod culture methods inadequate. Larvae can be easily transported.
Word origin: Centr, -I, -o (Greek). The center; a point, spur. pygm, (Greek) dwarf. The common name "Pygmy" or Dwarf" angel is apparent from the word root pygm. Centro may be in reference to the spine (spur) at the angle (The center) of the preopercle. The genus loriculusappears to be a combination of lori, (Malayan), a parrot, and -cul, =a, =um, =us (Latin), little. The Lori is a brilliant red parrot and again a word root (-culus) indicates something small.
The common name is "Flame Angel" which is attributed to the brilliant red color.
