After working with these fish for several months I've been blessed with a successful spawn.

I have a group of 8 adults with the dominate male showing his breeding colors above.

I have somewhere around 40 to 60 fry.  Above, they are around 2 weeks old.

Wow! A beautiful chap! And congratulations with the spawn...I guess I will be checking AB in 2-3 months... 😀

Somewhat out of topic: I think you got the real Hikari's... Have you spawn them? If yes, what kind of growth rate you are seeing?

(mine are by far the slowest growing Danios I've seen yet... I wonder if this is always the case...)

Hi Mike.  Honestly, I haven't pursued acquiring any Hikari.  Been on a mission to get everything converted over to HMF and working with some of the fish on hand that I've kinda put on the back burner.

I'm hoping to set-up the Devario sondhii again very soon.  If you are still interested in some of these, perhaps we can do some horse trading this fall when the weather cools off.  Wink

HMF == Tanner's influence? (I use his cubes in rivertanks... pretty nice and some fish loves sitting on them).

Sondhi, Hikari: let's see what happens in the fall... I think I'll be interested, but I'm not sure I can supply Hikari's: I am only raising 14... and at 3 months they are still circa 15mm Cry let me see if I can spawn them again. (Comparing to your Kerri's they are problematic: eggs are few, and the fry grows awfully slow.)

Laugh  LOL, in part yes, but they are just so handy and efficient too.

What are you feeding your Hikari to get them into spawning condition?  You might find that different foods provide different results.  For example, with my D. erythromicron, feeding them live brine shrimp, blood worms or mosquito larvae results in decent egg production, but if I feed mostly live daphnia moina, egg production simply explodes.

Just a thought...

Hi Dennis did you do anything special to get them to spawn? Not heard of D. meghalayensis being bred before.Cool

What is 'HMF'?

HMF ==> See Here. The sponge can be used in many other ways too.

D.erythromicron: Daily artemia and Sera micron, and I have them self-breeding for the most part.... most of the time I see young fry in the tank and numbers slowly increase. This will never produce large numbers, but does not require any effort on my part, only watching.... and the bottleneck is not food (I can collect eggs any time) but predation.... 

As for Hikari's: bloodworms. Not at the point of worrying yet.

Hi Matt, nothing special, quite the opposite really.  After a couple of failed attempts using a standard danio breeder set-up, I offered them a large clump of moss and still no interest.  At that point I thought I'd just load them up with lots of live foods and leave them on their own.  One afternoon during a thunder storm they decided to spawn in the course gravel substrate.  I'm not sure if the thunder storm played a major part or not because it all took place just shortly after I had turned the lights on in the fish room.

During the actual spawning event, the females would burrow down slightly into the substrate and the males would follow.  Be rather large and boisterous fish, an occasional egg would fly up to quickly consumed by a temporarily resting participant.  With a bit of luck I'll be able to get them to spawn several more times and see if this is typical behavior or not.

At any rate, I've got some where around 40 to 60 fry that are growing at a phenomenal rate.  They are very lovely fish and the adults have quite a bit of personality.  When I brought the camera close to film this video you'll note they act like a bunch of puppy dogs seeking attention.  These fish are quite rare here in the states and I was very happy when the opportunity to acquire them came along.

Just a quick update.  The images are of the fry at 26 days old.  Eating anything offered, bbs, daphnia moina, golden pearls, Repashy gel, etc.  Compared to smaller danio, these seem to be growing at a fast pace, 1/2 to 5/8 inch long (12-15 millimeter).

The fish really seem to go for it and I find myself feeding it more and more.  A bit too soon for me to have a firm opinion, I've only been using it for 3 months now.

Cute! They look like mini-Devario.

Dennis, would it be ok if we added a few of these photos to the species profile and maybe reproduce some of the info you've posted here. Full credit would be given of course.Smile

Here's the kids @ 90 days, virtual miniatures of the adults.  On a side note, we had such a hot and dry summer I was worried about my adult breeders and the heat.  At times their tank temperatures rose into the lower 80'sF, but they showed no signs of having difficulties.

I've now added photos and some of the info from this thread to the species profile. Thanks again Dennis.Smile

A couple more questions if you don't mind: how did you separate the adult fish from the eggs, and do you have any approximate idea of the incubation period or number of days before the fry became free-swimming?

Hi Matt, thank you for adding my bit to the profile for these fish.

The fish spawned the afternoon of Thursday May 31, 2012.  I believe it was shortly after 2:00PM.
On Saturday June 2, I noticed the first fry.  Over the weekend they began to attach to the tank glass.
On Monday June 4, the first fry became free swimming.

In regards to separating the adults from the eggs, no efforts were made during the spawning event.  The gravel substrate is rather course and provided enough cover to prevent too many of the eggs from being eaten.  As I was working in the fish room at the time, I removed the adults to another tank after spawning activity had ended.

Thanks again - Dennis

Hi Dennis are you kidding thank you for the help! This site would not exist were it not for the kindness of you and many others. :)

I've updated the profile again with the additional info.
