Breeding Journal DataSheet
This first post should be updated regularly to include new information as events take place or changes are made to your system
General Species: Corythoichthys intestinalis (Indonesian) AKA Dragonface Pipefish
Social Structure: Group with males and females, peaceful
Size of Individuals: about2-3 inches in length
Age of Individuals: unknown
Date added to Tank: 4/5/2013
Broodstock Tank Details Size of Tank: 10 gallon
Substrate Details: sand, 1/2 inch deep
Filtration Details: sponge filter
Water Changes: 10% weekly
Water Temperature: 75F
Lighting: moderate, fluorescent
Lighting Cycle: 14 day, 10 night
Other Tank Inhabitants: none
Broodstock Feeding Details Food Types: live copepods to start, and I'll try to wean them to frozen cyclops or other frozen foods
Feeding Schedule: continuous copepods, then twice a day frozen
Spawning Details Date of First Spawn: unknown
Spawn Time of Day: unknown
Dates of Consecutive Spawns: unknnown
Courtship Details: unknown
Egg Size: unknown
Egg Color: unknown
Egg Count: unknown, at least 30
Hatch Details Hatch Date: 1/30/14 for Crooktail
Hatch Time of Day: before noon
# Days after Spawn: unknown
Larvae Description: Tiny transparent 1/2 inch threads with heads and prominent eyes. Nearly invisible without a good light.
Consecutive Hatch Dates: unknown
Larval Tank Details Temperature: 75F
Size of Larval Tank: 2 gallon plastic fishbowl in a 15 gallon glass tank water bath
Substrate Details: bare
Other Tank Decor: rigid airline at 3 o'clock position to create kreisel water movement
Filtration Details: none , except naturally occuring bacteria
Lighting: ambient LED
Lighting Cycle: brighter during daylight, but still lit from neighboring larval tanks overnight until about the second week
Water Changes: about 10 % every other day, with siphoning of the bottom crud. If I didn't have rotifers in there, I might not need to do so much cleanup.
Larval Feeding Details Food Types: to begin: 1/2 gallon of my best Parvocalanus culture filtered, live isochrysis: 250 ml of a dark coffee culture. 2 days later, another half gallon of a different jar of pods, this one containing Parvocalanus and Apocyclops panamensis, filtered and added. Later, rotifers appeared, probably from the store the pipes came from, and what we think is Euterpina acufrons, a harpacticoid that thrives in live phytoplankton. It seems to have been contaminating my Parvo cultures.
Feeding Schedule: none. pods and phyto added as needed.
Metamorphosis/Settlement Date of Settlement Start: 2/11/2014
Days after Hatch: 12
Date of Settlement End: 2/22/2014
Description of Fry: At the settlement start date, they looked to be twice as long as they were when they hatched, but still very thin and threadlike. There is some pigmentation, with a pattern of reflective spots. Settlement is noticed when they have color, and appear to feed off of the bottom and sides of the tank. the one survivor appears to be 3-4 times as long as the day he was born. His body is more filled out and I can find him and see him without a strong flashlight.
Grow-Out Tank Details plan Temperature: 75F
Size of Grow-Out Tank: 10 gallons
Substrate Details: sand, 1/2 inch
Other Tank Decor: maybe a plastic plant
Filtration Details: either sponge filter or a power filter. Power may be best as it can function as a refugium for pods.
Lighting: ambient
Lighting Cycle: 14 day, 10 night
Water Changes: 10% weekly
Size at Transfer: 3 inches?
Age at Transfer: probably 30 days or so, or whenever I can get the tank ready and the fish acclimated.
Grow-Out Feeding Details Food Types: live copepods, and perhaps NHBBS until I can wean to frozen foods
Feeding Schedule: continuous until weaned, then twice a day with frozen or if eating pellets, 4 times a day
Additional Information These babies were found in the shipping bag when the pipefish arrived at a LFS. Crooktail survived 6.5 weeks. Now that I have brood stock, if they will spawn….
