From what I know it is more difficult to start the rotifer culture with eggs....... nevertheless since u bought it already, it should be hatch like the brine shrimps eggs. One more thing to do, remeber to monitor the situation closely. U need to add nanochrolis (I don't think the spelling is correct) when they hatch which is a bit difficult to see. One lazy method is to put live alage solution when u r hatching it so that the algae don't turn bad and there is food when the baby rotifers hatch.

There will only be female rotifers carrying babies only when food is plentiful.

Click on the link, then the 'Navigation' bar for the menu. U should find some info on culturing rotifers, brine shrimps, etc.

Hope this helps.

open vial, empty into a petri dish or plastic cup, add 20ml water, leave for 24hrs.

After 24hrs transfer to 250-500ml saltwater, add phyto- enough to tinge light green.

Once phyto clear- tinge water 2nd time.

After 2nd feeding clears, density will be dense enough to

Transfer to bigger volume (your actual culture container 1 or 2 or 3 or 4ltrs).

from then to infinity maintain your rotifer culture factory. :lol:

you only need 1 to hatch and you will get a culture. (one vial should contain abt 6000 eggs,if you bought the smallest)

Try to use pure nanno in culturing rotifers, it helps to keep the cultures cleaner. Easier to strain and feed to the tank.

yup, if that's your tank salinity.

although they are brackish in nature- they can be acclimated to full strength SW.

you want cultures to run as near as possible to tank conditions so that you don't send them into shock and die when feeding.

Hello Chinmo, kind enough to let me know the source of Rotifer. I am also looking for copepod culture. Thank in advance.

u can buy rotifers eggs from reborn, copepods think can only culture urself. ;)

Hi bawater, how long will a culture take to matured and ready to split for furthur cultures? am using rotirich for roti's food, adding 1-2 drop per day, cultures size...using 1.5l coke can. :huh:

i don't know with rotirich (even though i got a 2 year old bottle in the fridge), its yeast based and i find water quality issues with using it.(water spoils within 1 batch)

and i have to change more water = more money for salt.

currently i only use the phytoplankton concentrate from aquaz (pure nanno) and i can get a batch ready to harvest in 4 days. (to split into a few cultures maybe in 2-3days)

for a 12ltr culture i use up abt a bottle($10) just over a month- at your volume that bottle most probably last u 4-6mths :lol:

1ml of paste will feed 1million rotifers per day. but i use the eye method, just tinge the water green and feed again when it clears everyday/every other day. (2-3 feedings and its ready).

2 mins per day for feeding and 10mins for harvest, that's all i spend on it.

i mix half a teaspoon with new salt water in a 500ml drink bottle and leave in the fridge (and leave paste in freezer). use this bottle to feed the cultures for the week,this feed solution can also be used for tank feeding :) . That's how i can feed everything so fast. The diluted solution will keep for a week easily in the fridge.

and the paste in the freezer can keep for a yr.

my batches are in 4ltrs. and with the nanno i can reused back 50-70% of the old water after straining.(meaning a 30% water change every harvest). saving me in salt.

Hi Chinmo, why the sudden interest in rotifer culturing? ;) I thought baby seahorses go for larger zooplankton?

well... according to seahorse.org... if fed rots and bbs for the first week, will raise the sucess rate of them to adults. hence trying to culture lor :P
