Ok i started with 150-175 clowfish larvae now im down to 30. Pretty much they all survived the night. I added 4 to 5 drops of rg complete and a ton died. Is the rg complete the problem?should i switch to straight up nannochloropsis? Its really getting annoying that i cant keep them alive for the first 2 days. Any help is advise. Could it be something else?

Isn't RG Complete and nannochloropsis rotifer food? It's for feeding the rotifers that you then feed to the fry.

Using the RG Complete is normal. People use it to tint the water green while at the same time feeding the rots that are in the tank with the clown larvae. I do this myself all the time.

As for why the larvae is dying, could be multiple reasons so you would have to be more descriptive in your process. Some immediate thoughts that come to mind are how are you handling or collecting the larvae after hatch, are you using light over the tank?, temp and aeration, etc. Post a run down of your setup and what you're doing for some better advice.

Ok ill take a pic later. My one friend said rg complete wasn't the problem either. Heres my process. I collect the eggs using vossen aquatics larval trap (search on YouTube) i then stick them in the larva tank that has fsw. I had the heater set to 82 degrees. I have one air Stone under the heater. (idk how much air to put on). After transfer i go to bed. I wake uo turn on my 15w incandescent clamp on light Fixture and feed 3 quarts of rots. To my judgement they dont have to swim a body length to get them. They survive most of morning and by noon most are dead only 45 survivors.

Something that immediately jumps out at me is the incandescent light. You dont really need much light for the first 2-3 days. sounds like it could be too much, especially if you're not lessening the intensity with paper or other. A big clue to this is if you see the larvae almost face down on the bottom of the tank. Thats them trying to get away from the brightness. Airstone under the heater is good, ideal if you use one of those airstone bars that can run the length of your heater. bubbling shouldnt be very intense. just enough to deter the larvae from going near the heater. If you're getting a foam or collection of bubbles built up on the water surface,its too much.

Ok i always thought it was too much light but a couple guys said it wouldnt kill them that fast. Have about 20 left. Only one has died. Im the last 3 hrs

Thats a little too much light in my opinion.

are the clowns staying at the bottom of the tank? if so thats the good indicator that there is to much light.

I use the standard florecent bulb that comes with the older 10 gal tanks and still have to place 5 sheets of paper inbetween the light and the tank or it's to bright

Are you using newly made water, or water from the tank the larvae came from? A quick die off usually has something to do with parameters such as temp, water conditions, aeration, etc. The larvae should live for 4-5 days without food, so I suspect it's not the RG or your rotifer density. Most of the times I have had a large quick die-off I could trace it to my own blunders.....

Are you straining your rots or dumping the rot water into the hatch tank?

On post # 4 you move the fry from tank water to new water. That is your problem. They can not adapt to the change in water till day 4.

Ok i see why alot died off. I still have 30 going pretty strong no deaths since yesterday which is good. I do strain the rots amd then rinse them. I am planning on feeding TDO A on Monday instead of nhbbs.

+1. Most of the fry are probably going into shock from the abrupt change.

I usually take water from the parent's tank and drip it though a coffee filter into the larval tank. It's done on hatch night.

I do daily water changes useing parent water, never saw any ill effects.

Also in one of your pics you have the rg complete sitting next to the tank, i hope you put it in the fridge ehen done useing it as it can go bad fairly fast when left out.

Well i got confused on whether hatch night counts as day one. So this time i should try parent water?

This. Use parent tank water for the first few days of water changes.
