Breeding clownfish... Babies dying... Need help (1 Viewer)

[julio]

So im breeding clownfish and have all the basics down. First batch of 90 transferred into fry tank had 5 alive the next morning. Second batch i had about 200 transfered over and 8 alive in the morning. There is something im not doing or doing wrong to kill almost the whole hatch and has me puzzled. Fry tank conditions are as follows.

5 gal tank with parent tank water at 82 degrees
Bubbler making about 2 bubbles a second
Heater light indicator covered with electrical tape
All 4 sides blacked out and bottom painted white
2 quarts sieved rotifers added
2 watt led lamp lighting tank with paper towels to diffuse the light
Zero nitrates/ammonia

The last thing that i do after i gently scoop them out and place them in fry tank is add rotifer feed to the tank to help the rotifers stay alive a little longer and be more nutritious to the fry. What im thinking is im adding too much rotifer feed to the tank... 2 ml. It tints the water a green color but could it be choking them out? Before i tint the water i can see the fry swimming and doing good but after its greened i cant really see them all that well and cover with paper towels. I check on them in the morning.

Any ideas or advice to help my success rate? Thanks!

Is the fry water the same as the parent tank? Did you use a net to scoop them? Or how did you get them out? Did you see them acting like they were eating?

Turn the bubbler up.. make sure its in the middle of tank under heaters element.
The water must still have movement by air.
REMEMBER that light is the enemy at this stage. I dim things in the room to not shock them to death.

Thanks Lee... Ill turn the bubbler up. The light is 2/3 watts max and I also have the tank covered with paper towels so its not too bright. I start removing a layer of the towels at day 5. They say always trust your gut and last batch I kind of felt the bubbles weren't enough but I left it the way it was... should have known.

Chris, yes it was the same water as parent tank and I scooped them out with a plastic container. I could see them darting so Im pretty sure they were eating.

At this point Im convinced it was not enough air bubbles or too much rotifer feeding the tank.
