I have a batch of GSMs that hatched Monday night. I had ordered 2 quarts of live rotifers for overnight delivery. When they didn't show up on Tuesday, I called and after they checked with DHL, found out the shipment was lost. It was too late to get an order out for Wednesday delivery. I had frozen rotifers and figured I better at least try. I am on night number 2 with feeding only frozen and have only lost 3 fry so far. I will be getting my live shipment tomorrow morning, but am also curious about the success of using strictly frozen.

OK here is the deal, larvae from healthy and well nourished broodstock hatch with a substantial yolksac that can sustain them untill they learn to hunt and capture food. The frozen rotifers are not likely to elicit a feeding response in the larvae. It's up to you to figure out if they are eating them or not, if they are you should see the actual strike and take event and you would see the guts expand. With live rots the gut will turn silver, I don't know if that applaies to frozen. If they are NOT eating you are probably doing more harm than good by deteriorting the water quality. Just get the live rots in there asap and there is a good chance you will save some number of them if they were hatched strong in the first place. However rotifers are expensive and what you ordered is probably more of a "starter culture" rather than a foodsource. IMHO it makes more sense to culture the rots, wait for the next hatch and get them off to a good start.

I ve seen larvae go with no food up to for 3-4 days,
The frozen rots only work if you have live with them, it just "increases" the concentration as the larvae might take them up.
Judging by your location and service used it is likely you will get enough to feed them a bit and start your own culture.

Just to update those 9-17 gsm's that had to depend on partial live and mostly frozen rotifers came through just fine and I had to do the same dance two days ago with a mixed bag of gsm, fire and clarkii larvae. I'd say the mix was something like 20% live and 80% frozen, they are just fine at 5 days now and I have plenty of live to keep them going. I will always keep these things around for emergencies

WhateverWhen you are ready to be a breeder let us know
My clowns have spawned already & caught me by suprise...lol anyway Im sure they will spawn soon again...I have never tried breeding clown but now Im ready...anyone with great info please chime in I have been reading all day about setting up a rotifer tank...were do I start and were do I get the live rotifers from? and how do I make the green water??? I know Im rambling but Im ready to roll....tell me were to start!!
Thanks Joe
You can feed them a lot of stuff but remember they are only what they eat. IMO the question you need to ask (and I don't know for sure of hand) would be "does freshwater microalgae such as spirulina have the proper nutritional profile to raise baby clowns with rotifers being fed with it?".
I usually get live phyto and resting rotifers (cysts like brine eggs) from Florida Aqua Farms. Reed Mariculture also sells live rotifers and algae pastes that can be used instead of green water or has a back up in case of your phyto cultures crashing.
You can fed them quite a number of things, including yeast, but most do not have any nutritioanl value. If you do something like that you'll definitaly need to gut load them prior to feeding them to your larvae.
Yeast produces a lower count culture and makes them harder to maintain.

you guys are killing me ! lol
i just placed another order for the naturose, now i ll have to get the gps also lol
his challenge in raising larvae is very fascinating to me as a scientist. hopefully i ll have some success. ive acquired i believe ever food source attempted for larvae. now i just have to hope my pair spawns again!
I realize this is an old post, but was wondering how you made out using the golden Pearls? If it worked for you or not. Thanks.
