Clownfish Eggs in Display Tank not hatching?

[atp0726]

My SA Fancy Snowflake pair recently laid eggs on the underside of the return locline right next to the overflow for the first time (at least that i noticed). I first saw the eggs on Monday (pic from Monday)and they already had the 2 eyes visible. They have had that silver reflective look for at least 3 days now. From what I have read I actually thought they would have hatched by now?

I would like to give rearing the fry a shot and until I get the rotifer cultures going and the appropriate equipment I am not going to try and attempt it but I am trying to understand the hatch cycle. I have already put a clay pot in the tank with the hope they will start laying the eggs on it so it can be removed eventually.

I am starting to wonder if I may need to make some adjustments to my DT for better success. I obviously cant feed the recommended 5x a day but I could increase feeding to 2-3 times a day. I feed LRS reef nano only in the evenings currently. My temperature is also set to 77. Should I increase the temp? Sounds like temp effects the time it takes the eggs to hatch and I am thinking this may be delaying it.

I can't help much in this area but that is awesome. Do you have any pictures by chance?

Bump for some breeding/rearing expertise!

Yes, take another look. Added a pic from my phone after submitting the post.

Odds are high that they will be eaten upon hatching, if they do hatch. Lots of great threads in the breeding section, but not so sure about anyone with luck in the display. I believe light can also affect their hatching

Crank the temp up to 80 - 82. The eggs will hatch faster.

It takes 7 to 8 days to hatch. On the 7th night from the point you know the were laid wait for the tank lights to go off. 15min after lights out shut your pumps and wavemaker down. Wait another 10min and shine a flashlight down from the surface of the water but not at the eggs. Soon you will see little fry dart up to the light at the surface of the water. At this point is when you can take a small glass bowel and scoop them out of the DT to a grow out tank.

You don't need to change feeding habits or change any thing in your tank. The male will care for the eggs during the process.

Will they hatch on the 7th or 8th day regardless of DT temp?

 

[Tbabcock]

Yep...

The only time temp plays a part is in there grow out stage. The closer your get to 80 will help accelerate them to the meta stage.

My clown pair have been breeding/laying incessently for over 2 1/2 years straight. Never missed a beat when I moved them (2mths ago) from their 38 cube to their new 150.
In the cube I kept the salinity at 1.023-1.025 and could time the hatch to the 1/2 hour without fail.

Now that they are in their new home, that has a stable salinity of 1.026, the eggs take a day or so longer to hatch.
The extended time, is either due to the increased salinity or the fact that I don't feed them as much or as often as I used to. Could be a combination of both?

Good point, didn't think about salinity. Mine is right at 1.o26 as well. I need to find where I read it, but someone recommended lowering SG to 1.024 if you are planning on removing the eggs, using tank water in fry tank and feeding the rotifers. Had something to do with the rotifers needing to be at a specific SG for cultivation and would go into shock above 1.024. All from memory so please dont quote me on it

Most likely your paramitors are still off. I have several breeding pairs and experience a brake in there laying period as well as a change to the hatch period when there environment changes. After the tank matures you will see things back to normal.

I have several breeding pairs and my SG is 1.025. I keep my rot culture at the same SG with no effect.. in fact the grow so quick i have to thin out a 5gal bucket of them monthly. Great for feeding the reef and Wrasse.

I wish they would stop breeding. Ever sense they started, the male has been a jerk and is constantly redecorating the sand bed around the overflow base.

Put them in there own tank and let them arrange the furniture.. lol
There is no way to train these guys when you have one set on doing his thing.. trust me i gave 12 pairs an a couple if them are just bull headed.. the maroons are the worst..

Ha, Ha. Nope. They lost single family dwelling when I broke their IM 38 down and put them in the 150 Penthouse with a single Dory.. Where do they prefer to hang out?
At the bottom behind the center aquascape where all I can see, is the mound of sand that the jerk makes...

lol... that's crazy... have you tried to get them to host a nem?

Mine all have condos.. lol
