Breeding Journal DataSheet

Yellow Watchman Goby Social Structure: pair Size of Individuals: 1.5-2 inches Age of Individuals: unknown Date added to Tank: Hatch report from a friends' eggs, my broodstock added 7/12/2015, details in a separate journal Broodstock Tank Details Size of Tank: 17 x 19 x 27 inches Substrate Details: full reef, sand, corals Filtration Details: basement sump with live rock, skimmer, refugium, etc. Water Changes: unknown Water Temperature: 80F Lighting: LED reef lighting Lighting Cycle: roughly 7am to 9pm? not my tank... Other Tank Inhabitants: corals, pair clownfish Broodstock Feeding Details Food Types: unknown Feeding Schedule: unknown Spawning Details Date of First Spawn: 4/29/15 Spawn Time of Day: unknown, eggs discovered in morning Dates of Consecutive Spawns: May 19, June 10, June 28, all are guesses since spawning is not witnessed. Courtship Details: unknown Egg Size: 1mm Egg Color: yellow Egg Count: between 10,000 and 100,000 Hatch Details Hatch Date: 5/3/15 Hatch Time of Day: after lights out # Days after Spawn: 4 days Larvae Description: black eyes, yolk sack slightly larger than eye, transparent body, pectoral fins, caudal fin, dark spot mid body, functional mouth, gut looks well developed. Consecutive Hatch Dates: may 23, june 16, July 3, 2015 Larval Tank Details Temperature: 76F Size of Larval Tank: 17 gallon BRT filled to 10 gallons Substrate Details: none Other Tank Decor: none Filtration Details: none, but the tank is fed lightly with live phytoplankton, and some kind of macro algae grows on the walls. Lighting: CFL in clamp on reflector mounted to side of tank , and blue led strip on same side Lighting Cycle: CFL is on for 14 hours during the day, then off 10 hours , and blue led strip on same side is on 24/7 Water Changes: none . tub is pretty clean, though teeming with rots, copepods and brine shrimp, some of which are propagating in the tub. Larval Feeding Details Food Types: euterpina acutifrons, Parvocalanus crassirostris, Apocyclops panamensis, rotifers, live Tetraselmis, Isochrisis and Rhodamonis phytoplankton as well as RGcomplete to feed the rotifers. Highest population is a super small rotifer up to day 14, then plicatillis rotifers will be added, and NHBS at day 20. Feeding Schedule: tank assessed twice daily and additions as needed. Metamorphosis/Settlement Date of Settlement Start: July 21, 2015 Days after Hatch: 18 days Date of Settlement End: Completely settled at July 21, day 18, but not yet metamorphosed at day 23. Description of Fry: Pelagic larvae are transparent with 3 glowing dots under the flashlight, and are constantly darting in the water column. The settled fry cling to the wall, as if resting, occasionally darting out for a swim or to find more food. It's body is opaque and the eyes do not glow as brightly when hit with a beam of light. There is a vague yellow color just behind the head and a row of dots from the back of the head to the tail which could be spinal column. Metamorphosis happened some time after that. The tub was so difficult to see into, that I am completely unable to tell when they became little fishes. When I transferred them to the breeder basket in a real aquarium, they had fully transformed, 8/23/15.
Grow-Out Tank Details Temperature: 80F Size of Grow-Out Tank: 15 gallon glass. Fish are in breeder basket Substrate Details:none Other Tank Decor: small 3/4 inch pipe fitting Filtration Details: sponge filter in tank Lighting: CFL clamp on light Lighting Cycle: 14 hours daylight, 10 hours night Water Changes: none yet Size at Transfer: 3/8 inch approx. Age at Transfer: about 7 weeks. Grow-Out Feeding Details Food Types: Small pellet food from Argent and Otohime, "New Wave Arctic Copepods" from Brine Shrimp Direct, NHBS Feeding Schedule: twice daily Additional Information From FishBase: Dorsal spines (total): 7; Dorsal soft rays (total): 10; Anal spines: 1; Anal soft rays: 9. Predorsal scales absent. Occurs in two color phases, one yellow and the other with whitish ground color; both forms with 4-5 dusky bars (although faint in yellow fish) and fine pale blue or white spotting on head and anterodorsal part of body and fins. A dark brown streak above maxilla (Ref. 27362); further characterized by: brown snout; presence of thin brown line along edge of upper jaw; united pelvic fins, presence of frenum; longitudinal scale series 92-95; head without scales; greatest depth of body 4.4-4.6 in SL; rounded caudal fin, about equal to head length (Ref. 90102). (No Pictures or Videos in the Section Please) Miscellaneous Information: You will be required to provide photographic or video evidence in this thread of each event submitted for the MBI Program.
If your thread does not contain these photos the MBI Committee will not be able to approve your reports. PHOTOS AND VIDEO S MUST BE PLACED IN ADDITIONAL POSTS, NEVER IN THE FIRST POST IN A JOURNAL.

An aquaintance emailed me about his watchman gobies who spawned on Wednesday. Would I like the eggs? Yes, indeed! I'm very excited.

I am preparing the tub. A BRT of course. About 10 gallons of filtered(100 micron, as there is stuff in my mixing bucket) saltwater, airstone, 50 watt heater, as it is warm in my basement, but not warm enough. Bleach. Dechlor, test, then additions of copepods and rotifers after the goby eggs hatch, and an assortment of live phyto, which I happen to have a lot of, these days.

We easily detached the bunches of eggs from the rock work, and bagged them up and took them home. They started hatching in the bag. I put the remaining eggs in a glass jar submerged at the bottom of the tub, with an airline to keep the water moving, if not the eggs. 10 minutes after lights out, they started hatching like mad. The hatched ones easily swam out of the jar. I've added a mix of live phyto to the tub, but I'm waiting to add the copepods and rotifers until the eggs mostly hatch. Very exciting!

These guys hatched for hours, and there were thousands, but many died overnight. It's good, because I don't have enough food organisms for 100,000 larvae.

About a mm. but with dark eyes and a functioning mouth. So much better than damsels...

Video link works. Those are tiny! Looks like one of my pod cultures! Are you feeding the combo listed above, or starting with one type of food?

Let's see: small and large rotifers, 3 kinds live phyto, supplemented with RGgreen, Apocyclops panamensis, Parvocalanus crassirostris, and Euterpina acutifrons. Plus probably some ciliates. The kitchen sink.

Yes, sometimes it is hard to determine, with a flashlight, if the bright spots I am seeing are larvae or copulating copepods.

for such a tiny fish that's a huge egg mass, instant water swelling ! Great to hear how well they are doing, one of my favorite families.

Did it appear they were eating anything from the micro fauna salad you offered?
