Breeding Journal, Species: Cryptocentrus cinctus

One other fun fact: I can find the watchman larva without a flashlight if the water is slightly clear!

Renaming the tubs: Tub 1 is the watchman tub, Tub 2 is the new tub with damsels and rubys only.

The watchman is starting to dislike the flashlight.  It darts across the tub when I shine it on him/her.  Getting bigger with a reddish hue to the eye and the middle spot.  Sure wish i could find NicoleC's postings on RC about this species.  She was attempting C. cinctus when I was starting out with clownfish a million years ago, and had a thread-of-the-month award in the fish breeding forum.  Anyone have her contact info?

I found her threads by searching for NicoleC rather than NicholeC.  What fun!
 
Watchman larva still doing well, eating, being a good citizen with all its neighbors.  I just fed the tub RGgreen, and called it a night.

Kathy,
You better get some sleep soon or you'll be worn out before the Workshop! Sounds like you'll have lots to talk about.

Thanks Tal, sleep is important, if not for the fishes, then for me.

Day 16, and the watchman is fine.

Day 17: I clearly saw the watchman doing its darting and swimming this morning, looking fine.  
 
I could not find it this evening.  I searched and searched.  I found the damsel larvae a couple of times, but I began to despair that the watchman was no more.  I don't know what possessed me, to scan the sides of the tub, but there it was, adhered to the side, hopping around at times, but seemingly settled.  It does still look like a larva, but it is opaque like the oceanops gobies get just before meta.  I had thought that meta was weeks away, but maybe copepods make a difference for watchmans and they grow faster.  We'll probably know tomorow if this is the beginning of meta or just a stage before death, but I think the larva looks healthy.  We'll see.

I just found this on the Breeders' Registry:
"
...The Yellow Prawn goby, Cryptocentrus cinctus, has also been reported to the Breeder’s Registry database. Information is not as complete for this species, but the pair was maintained in captivity for 2 years and were moved to a new tank 6 months before spawning. No physical differences were notated aside from the possibility of size which was 80 – 90 mm (~3 – 3.25 inches).
Hatching was typical, occurring after dark. The larvae were ~2.0 mm in length and some yolk sac was visible. The larvae were fed with rotifers enriched with SELCO. After the first week the larvae settled to the bottom of the tank. At day 15 Artemia nauplii and copepoda were introduced (again enriched with SELCO). Metamorphosis occurred at 20 – 25 days and high mortalities were experienced. ..."  
So I'm not too far off thinking that meta may be starting, even at day 17.  Or death.

I found him yesterday morning but not evening, and not this morning.  Oh well,  there are more eggs coming, and perhaps next time I'll get more than one to live.

Got back from MBI this evening and couldn't find that goby, until I did!!!!
Definately settled.

The last two look like the line of spots could be indicating a spinal column.  If you imagine real well, you might see flexion.

Large goby darts very fast, when I can find it.  Small goby still has not settled. so weird...

Both gobies settled now.  When my breeder box comes in, I'll transfer them to a real tank.  Can't justify the real estate for a BRT housing two tiny juveniles.  Also can't see them readily.

These two gobies are from the brt that had been fed all 3 live foods you had to offer, correct? I checked back in the thread but things got confusing lol

rotifers(small ones), parvocalanus, brine shimp, live n dead phyto.
 
Sorry for the confusion.

Any updated images of the post settlement fish?

I finally do. I moved them today, and finally got a good look at them.  The bigger one was more bothered by the transfer and acclimation, but the little guy seems to roll with the punches.  Little One is more yellow, Big Guy is a little grey.  That may just be stress. Pix in a little while.

In the BRT just before transfer.  The standpipe is a one inch , one and a half inch outside diameter:

better than the bigger one:

The nice thing about the breeder basket, aside from being able to see them well, is that I can see them eat.  Thankfully, they are eating Otoheim B1 and the Argent shrimp feed that I happen to have on hand.  Previous to this move, I was not sure what they were eating, since brine shrimp were breeding in the BRT and there were leftover copepods, though I think the rotifers had died off by the end.

Their color is so different they almost look like two different species.  Or is that just the lighting?

Neither,
 
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).

They look great!

Thanks Jake,
Dave, I agree they look like different species, partly because of the color and partly because the grey one is so much more developed than the yellow one. The only other species I had in the tub was a damsel , IIRC, and these guys are surely watchmans.

In addition, rumor has it that the grey could be an indication of gender, grey being female.  There is also the observation that the grey ones are the bigger ones of a batch. Another observation is that the color can switch back and forth.  However, the  broodstock pair for the eggs I am using are both yellow.  Gobies are known to switch sex back and forth, but I can find no definative source of info about the watchmans by google.

Got a new batch of eggs.  They came on two strands. One strand hatched sometime today into the methylene blue, and the thousands of larve mostly died.  In the other strand, thousands died in the egg, and some were clearly unfertilized.
 
So again, I got about 25 survivors, and I'll add them to the BRT this evening with Isochrysis and Parvocalanus.  We shall see.  They may have some G. okinawae larvae in with them, if those eggs hatch tonight.

I think I ran out of luck this time.  I can't find any survivors.  Had I been home when the thousands hatched, I would have been able to rescue them from the crowded conditions that likely did them in.  Gonna have to rethink this one.

So Kathy, how many juveniles do you have? Nevermind - I see 25 above!  

No, sadly, I have zero from the latest batch, 2 from the earlier one, very cute, one gray, one yellow, see pix above. Next week will be 60 days.  I suppose it is possible these two will mate, and then I'll get the full MBI credit, but I continue to look for a good adult pair.

I was waiting for the 60 day report before I move these guys to a new home, different tank, as we are re-doing the basement. Snapped a picture for the 60 day report, and I'll be dag-nabbed, if the gray one is turning yellow.  Still has the light blue tips on the dorsal fin...

They have both grown like weeds.  Their full bellies are ever present. I've enjoyed these so much, I wouldn't mind owning a spawning pair.  If I can't find one in time, perhaps these two will fill that bill.
