5 days in and all going well, eggs are still there. adults are doing fine eating like pigs, both have massive bellies 

eggs developing well if my calculation are right they should hatch thurdays night at 9 days
 


 

well theve not hatched at 10 days!!
 
but my female looks gravid to me, what do you guys think?
 



 
look for the female 21 seconds in as she turns towards us,  rather large belly
 

 
 

well all but a few clear slithers were gone this morning, which mean they hatched day 10
 
laid on the 10.4.12   hatched on the 21.04.12
 
just need the next nest now witch hopefully will be anytime soon

respawn today,  and i may have disturbed them as they seem to have split the nest
 
caught them in the act though 
 video

pics


 

well 7 days in and both halves of the nest are still going strong, hope i have enough rotifers!!

females gravid again!!!  and expecting a hatch tommorrow night,
 
this will be my first attempt to raise eggs ever!!!
 

Good luck mate!

thanks

well hatched last night , currently in brt
 
will try to get some pics

 
Not liking my chance of getting a pic of these fry?

a couple of videos
 
nothing happens till twenty five seconds in

 
not sure if this is the t position they talk about, if so its quite brief

well now starting my third attempt to raise these
 
realised i had been using rotigrow plus to feed rotifers and for greenwater (now on omeaga) and probable too much of it
 
going to try to be conserative with greenwater and make sure i dont over feed rotifers as well

well i have managed to hatch a small nest, and have about 20 in a brt, if there still there tommorrow then i will have broken previous attempts and got to day 4

Good luck!

Thanks

Things I've changed this time include

Raising the led
Not mixing up rotigrow and omega
Putting a lot less Rotifers in, at least half as many (hoping I have a gauge for the sort of density needed now)

Only day four today but I've only lost one or two from this whole batch

Another 26 days or so to go to meta now :-)

In the future I suggest only changing one thing at a time so you know what made the difference.

"Making captive breeding easier."

8 dph

 

 

ok so started losing a few from around 12dph think its possible a nutritional thing my rotifers seem to be struggling.
 
have noticed black spots developing behind the stomach  and near the tail!
 
think im down to less then 10 fry left

ok, added my first batch of nhbs tonight as i think nutrion could be why im losing a few
still have a  handfull left at 19 dph

Some gradual die offs not sure if it's an approaching meta thing! Have maybe 3 or 4 left now

Have some dodgy I phone pics/ video 24 dph!!

http://i177.photobucket.c...01_photos/73b779c3.mp4

well lost the last one today at 31 dph  non made it to meta,  but i think it was a good effort considering i only started with 30ish,  and its only my third attempt
 
thought i'd sum up some of my very basic observations here, so there all in one place
12-15 dph started losing fry (possible nutrition)  est 1/2 cm in lenght
14 dph noticed black marking appearing behind the stomach and near tail.
22 dph est 6 left (1/2+ cm long est)
24 dph 3/4 left,  some seem to be showing a blue/ grey colour to head area
28 dph 2 left
31 dph lost last one, had been moving strangly near the surface the night before

well about time i updated this
 
after lots of failed attempts,  ive sussed out the sort of density of rots and green water needed to get to the 30 day mark,  im still getting big die offs from around day 12
 
but i currently have three at 33 dph,   still no meta, but there showing a slight blue hue around  there heads,  which i hope to be a pre meta thing.
 
this is my record but im hopefull to get some through this time
 

quick video, worth watching untill the end.

 

 

With full colours

Very nice,Matt!.Congrats!.
You should see the black line as the first color of meta.Resting on substrate (settlement) can happen shortly before or after.

cool thanks  luis these  guys seem to settle first then get there colours
 
two out of the three settles now were at fourty four dph

Congrats on the success so far.  BTW, it's really neat to see the "White Stripe" variant of the Sharknose Goby being done!

Thanks matt, that's something that had intreaged me but I haven't been able to find any info on

Obviously, ora produce electic blue ones with a prominent extended yellow nose stripe
Where as mine are very pale blue, with a short white stripe on the nose. Are there more variants that you know off? I have seen a drawing that suggested a yellow body one exists but I guess this could be a miss Id. or is natural hybridisation a factor here?

Really interestingly the babies seem to look like the ora colours but I guess it will be hard to guess what will happen as they grow

I've found these a lot harder then people make out (maybe because I'm a novice breeder) but have had way easyer faster results with Oceanops. It's taken a lot of tries to get 3 through and one of these still hasn't settled coloured at 50 dph?!?

The only other real evidence I can find of the evenlynae being breed is the likes of ora and proaquatics and some non supported threads that claim to sucess on first attemp ect. another reason I was soo keen to get the reports in on this species

Well 51 dph and the final evelynae has gained it's colours, was very happy when I checked this morning, especially as he had been looking ropy the day before

found this info regarding the white stripe
 
Body long and cylindrical with two dorsal fins. The mouth is underslung, or shark-like. Upper body dark, underside pale. Three distinct color patterns exist, each in a geographical region:
Brilliant blue-stripe pattern, with a brilliant yellow stripe in front of each eye, joining near the tip of the snout to form a 'V', on the back these 'V' fades into pale or brilliant blue body stripes. These patterns are found in the central Bahamas and extending south to the north coast of South America.
Pale blue-stripe pattern, with a yellow stripe in front of each eye, joining near the tip of the snout to form a 'V', on the back these 'V' fades into yellow body stripes. These patterns are found in the central and northern Bahamas.
White-stripe-stripe pattern, with a narrow white stripe in front of each eye, joining near the tip of the snout to form a 'V', on the back these 'V' fades into bluish white body stripes. These patterns are found in the mid-Caribbean.
Size of all patterns up to 4 cm.

Being transferred to a holding tank, to free up the brt!!

Being transferred to a holding tank, to free up the brt!!

Ahh lost one after the transfer hope the other two do ok

my neons hatch on day 8 at a temp of 78 salt at .23 but they die on day 9 or 10 for some reason i start dripping in clean water at day 3 or 4 and keep rotifers thick in there so idk whats up but i try somthing new everytime havent found the magic yet so good luck on yours i want to master it so i can move on to dottybacks clowns are easy

Well a lots happened, I lost one other off the 3 I had that settled shortly after moving them to a little pico tank, so I have one remaining that should be at 60 dps very soon.

I've moved house and set up a new broodstock system, so the adults are now in a 2 ft tank as part of a 700ltr system, with 10 tanks, and the remaining juvenile, is in with 10 Oceanops and some baby clowns, need to push on with my grow out system in the new year!!

Now before the move my adults stopped spawning, and tobe honest I thought that was it, but they settled in well and spawned for me yesterday just 12 days after being moved!!

My main mission now is too hit some bigger numbers and build up a stock of juvi's before the pair retire permanently
