    I caught over 100 clownfish larvae last night and they seemed very strong. Now this morning most are swimming in circles in the entire water column.

    Maybe they are all "real" NEMO's born with one tiny side fin causing them to swim in circles? :p

    No no....jokes aside....will be interested to see what the answer is....their is a guy in PE thats been breeding them for a while, maybe you can get hold of him and ask?

    Water contained nitrite.

    No. The water I collected the past weekend is perfect. You must remember I collected it to fix the nitrite issue :).

    When taking larvae out of main tank you need to place them in the same water they came from.

    Prepare water so you can do a water change on the night.

    Unfortunately the main tank water is the water source containing the nitrite and larvae are transferred using the main tank water. I did a lot of water changes now to fix it.

    Was the tank temperature the same? Was the green water good (you can just see through it), were the rotifer good? Did you have an air stone in the tank? Do not use a pump, it is too strong, or any filtration, for the first week or so. We used to vacuum up the dirt from the floor of the tank with a tiny air tube to keep it clean.
    Cheers Anita

    I am in the process of calibrating the heaters to keep larvae water at same temp as main tank.

    A issue i have is that when i buy four thermometers there will always be one that is higher or lower in reading. Anyone experience this with thermometers before?

    I don't tint larvae water.

    Yes except some floated at the surface due to rough handling during sieving process - i will fix this.

    Airstone with a slight trickle under heater.

    No filtration/pump used.

    I use a rigid airline too.

    How are you feeding the rotifers?

    Maybe things have changed since I last bred clown fish but the rotifers had to be fed all the time, they lived constantly in green water, if not they have no nourishment for the fry when they eat.

    Many still use that method and i don't mind experiencing with it as long as i get some test strips so that i can test the NH3/4 and No2 of the nanno. Joyc D. Wilkerson used both ways with great excess.

    I must add that "old" roti's are removed every day and replaced with "new" rotis.

    We bred thousands of many different clown fish species, the first were real trial and error, but over the years we managed to get it to a fine art. We did not really use test kits or anything in those days. Brewers yeast was also added to the green water to add nutrients to the rotifer, once they were about 2 weeks old, they went off the rotifer and onto newly hatched brine shrimp that had been fed green water/brewers yeast and Spirulina. I have some old photos of some of the fry, I will see if I can get them posted, cheers Anita

    More important is that the tank they come from and go to are the same temperatures.

    See below some of our baby clown fish back in the early 90's......
    The Fire Clown in the photo was called Lucy, she had many, many babies!!
    We kept each clown pair in a separate tank, rather than in the main tank.

    I agree with you and it is very frustrating when you have thermometers supplying different temp readings within the same water sample. I guess it is a case of exchanging them till you get a complete match as all my tanks has its own thermometer.
