My clown spawn hatch last night.

[Sport507]

Thank for posting your thoughts on this Whip.

I done a half gallon water change last evening but as I said earlier I hadn't seen any growth at all the first days. I think I have narrowed it down to lighting. The reason I say this is that I had a florescent light in the closet same wattage but much brighter. When I put this on I notice the few that where still left changed there swimming. They starting darting as though they were catching something in the water. I had not seen that behavior from the being.

I feel like the ammonia is causing the problem now after last night loses. Not to be cruel but I think I'm scrapping this try, cleaning things up for the next hatch. I think now that I'm wasting time trying to save the last few because they are in such a weakened state from not eating. Also I've used a bubble bar the whole time would that have made any difference? Here is a pic of the difference in lighting.

what have you been using for air?

the bubbles under the heater are to give air to the tank and to prevent the fry from hosting the heater.

This si a very frustrating thing. I had a pair of black oynx that i was breeding and got about 200 fry out of 6 batchs. bad rate. I am moving so i sold them to a friend that wanted to try his hand at the whole breeding thing. Good luck and hope you figure this out. Just keep you head up it is very frustraing.

Congrats on the babies. Just a heads up, I had that same heater in my sump, after a few months the blue dots started coming off, they made it to my dt.

I would like to thank everyone here for the help and comments, what a great group of folks. I'm ready for round 2 and it looks like they are going to spawn on a slate I put in the tank, that take a lot of work out of it. I'm not discouraged, I will have the same learning curve everyone else has just to figure out what works for me and my system.

Here is a pic of the fry tank for the next run. Again if anyone can see something I'm missing feel free to point it out.

Thank you all again.

Double post!

What was your lighting before? And what was the lighting when you noticed the darting?

Just curious as I will be going through this soon if the eggs ever hatch..

Sorry, I missed your post yes the bubble wand under the heater is what I've used.

Should I be using and air stone in the corner?

Sounds like you’re on the right path. I would definitely try blackening out the sides. Picture dust floating through the air when you have a dark background. You’ve got to make it easy for them to find the food. Couple questions:

1. How stable is your temperature?

2. Did you add algae to the fry tank?

3. You’re not adding rotifer water to the fry tank, right? The ammonia can get really high in a rotifer culture. Some folks even rinse the rotifers before adding to the fry tank. I’ve not found that necessary.

I keep my lighting fairly low for the first few days using indirect light from a 40 watt CFL. I slowly bring the light intensity up each day by changing the angle of the light.

Remember your clowns are new at this, so dont expect big numbers early in their spawning. You will see their nest get bigger and bigger, and see your survivors increase.

I use a 13W CFL about 18" over the water during daytime hours. At nighttime, I leave it on but turn the light away against the wall. That leaves them some light ot see and feed. I dont do a true lights out until after meta.

Give them some good aeration, but dont make them struggle to swim. You should be able to tell how hard they are struggling against the current.

My light was an incandescent 15-watt and I change it to a 15-watt florescent light that when they started darting but by then the ammonia had gotten to high and I was down to 6 or 8 so I scrape the project for the next try. My lighting differences are all posted in my above posts.

As stated in my early post I was running a temp controller and it never varied more than one degree, 79-80.

I added phyto to the fry tank just enough do tent it lightly.

No, I used a sieve to add the rotifers to my tank.

Sides black out now posting again the pic in my early post.

Sounds like you are ready.
My lighting is the same as hvacman. He just did a better job explaining it.

You do not need a fancy light or a air stone. I just had a batch of eggs I am raising now. I had 30 fry to begin with. I lost 4 during the process. I think those were weak to begin with. On the 20th day, I lost 16 more because of dirty water. I did a quick water change and was lucky to save the other 8. Here is my setup. Good luck to you.
