For me it varies from batch to batch and my overall numbers are poor compared to others here; there are many variables that have to be met miss one & the whole batch can go down the drain.
again it can vary all over the place i had my pair for 4 years before they started laying eggs.
For my pair the normal routine is this: eggs laid (10) days later they hatch, she usually waits 2 to 3 days before the next batch is laid down, and she has thrown me a couple of curve balls by double clutching; new eggs on old eggs.

:sad1: ah gee thanks; lol. Let's see a PLAYOFF CHOKE; who would have thought that; i guess this year we just decided to change it up that's all, instead of a 2nd round meltdown we exchanged a president's trophy & some franchise records for a 1st round embarrassing exit.:furious:

Hi, I have been following this thread for a while. Marc tipped me to it when I messaged him about my Maroon Clown eggs. I have one batch at the 3 week stage and lost the last batch to a strange incident. My rotifer culture seems to have some kind of small brown worms swimming in it. They don't look like bristle worms but I could be mistaken because they are small. They are about 1/8 an inch long.
My last batch of baby clowns all died in about 2-3 days. When I was cleaning the tank I noticed there were other things swimming in the water. I thought they were adult brine shrimp but it appears they are something else because when I checked the rotifer culture it had the same creatures but larger. I wish I had a picture of them and I will try to get one soon.
I have another clutch of eggs that will hatch tonight so we will see if the process continues. I think I filtered out the unknown creatures from the rotifer tank with a brine shrimp net.
Has anyone had an experience with their rotifer culture being contaminated by another species?
I did refrigerate some rotifer cultures a week ago. I’m not sure they are good anymore but I could try to start another culture. How long to rotifers live in the refrigerator?
Sorry for all the questions but I really don't understand what is going on and you guys seem to have the experience.

1. Where did you get your culture?
2. Did you use recylced tank water (plus your starter) to get the culture going? or fresh RO/DI (plus your culture)?
Kurt
I got the culture from Reef Nutrition. I used fresh saltwater(RODI) to start the culture and it was fine for at least the first 2-3 weeks. My first batch of clowns is past the rotifer stage and eating bbs. It was the next batch that died and when I noticed the contaminant. I might have contaminated them when I was performing waterchanges with the rotifers.

Tough to say where the contaminant came from, I've heard they can be easy to get. From my readings the typical types of contaminants (ciliates sp.) in mass production rotifer farms compete with the rotifers for food thus lessening their nutritious value. I wouldn't think that they would harm the fry but most likely make the food less valuable. How does this solve your problem.... It doesn't
I know off no way to remove the contaminant from you rotifer tank. Some of the papers I've reviewed say that you can try a plankton sieve 53 um and use the "sieved water" to capture very small immature rotifers in the hopes of removing the larger protazoa. Perhaps then you could restart a clean culture.Kurt

On a side note 10 days ago I began experimenting with rotifers. I took 5 ml from the rotifer bucket and 16oz of RO/DI 1.025 sg/SW placed them in a mason jar and fed them daily 4 drops of rotifer diet. No aeration, just a sealed lid. After 5 days I moved them to a 1 gallon plastic pretzel jar (filled with SW) and upped the feeding to 8 drops daily, again no aeration. This morning that 1 gallon jar has a dense enough count to harvest from.
It shouldn't be hard to examine 5ml under a scope (I'm betting you have access) for larger contaminant protozoa, but that of course doesn't mean they cannot slip in.
Good Luck

back to regular progamming.

@ Nanz; cool avatar picture by the way, i would have to agree with landlord that the source of the contamination could be from who knows; I know that does not really help you out at all but i would follow the advice already given and restart the culture in clean water and go from there; the only thing i have noticed show up in my rotifer culture has been bbs, not real sure how they got in there but from time to time i get some; i don't worry about it as they don't seem to bother the culture and i use them as "a canary in the mine" if the water quality is good enough for them to grow then my rot culture should be ok as well.
@ landlord I don't mind at all that's the reason we come here, to try & help each other out.
I did get a call from my lfs yesterday and they want some more so that's on the list of things to do for today as well as a bunch of wc's on the tanks, My wife and i have a wedding to attend this weekend i have a friend coming over to feed and take care of all the babies should not be an issue though as my latest batch is already on to bbs & oto a.

Thanks for the complement on my avatar.
Thank you for letting me post within your thread. I have learned so much from your thread. I found out at lunch that they are indeed brine shrimp but very adult in size, hehe. I must have dropped some eggs in the culture by accident.
My baby GSM clowns are doing good so far at 3 weeks. I have about 50 of them. Its hard to count the little guys. If you don't mind I can post an updated picture of them.

Good to hear that you found an explanation to what the critters are. Glad to hear that the thread may have been some help to you it's one of the reasons i started one as well as it's nice to have a running document of ideas, answers, problems & questions, lol. Nice work on the GSM they seem to be a bit harder to raise in the beginning; have you read agsansoo's thread here you may have to look it up but he was raising maroon clowns as well. I have a bonded pair of GSM as well they were my xmas gift to myself this year, no eggs yet from that pair but i am hopeful that maybe sometime in the future. Sure if you have a picture of the little ones post it up.

Well yesterday was a disaster. I noticed my Fry have been in 83 degree temp with 1.025 salinity. I was in the process of moving about 50 to the growout tank and lost all but 3
Just currious but what temp and salinity do you guys run your larva tanks at? Mine are at 83 degrees and 1.025.

Are these MSG clowns?
Do you siphon them out of the Display Tank or do you place the eggs in the Larva tank? If so then how do you lower the salinity? Do you RO/DI drip water in to the Larva tank tank?
My last two batches of MSG clowns all died in 48 hours. I don't know how I was so lucky with the one batch which was great until I tried to lower the temp. These clowns are 4 weeks old and Im afraid to lower the temp again from 83 they will die.
My display tank has a salinity of 1.025.

Sorry to hear about your losses; Maybe you moved them to soon, and how did you transfer them? with a net? Did you try & match the water parameters between the two tanks.
For what it's worth we just had a random heat spell hit my area a couple of weeks ago and my tanks due to their location pushed to 87-88 deg. for 2 days, i was fortunate though and did not loose any larvae so i don't know if the 83 deg. temperature was the issue.

Yes i lower the sg of the larvae water usually the day after hatching, i have losses right after hatching so i remove a gallon of water from the larvae tank while cleaning up the zombie's on the bottom and replace that gallon by dripping in ro/di water. My dt tank runs @ 1.026. I lower the sg of the larvae tank to help bring it closer in line with the sg of my rotifer culture.
