Roti-Rich... a no-no

[GreshamH]

The cod people switched for reasons other then cost really, all though that was/is a factor. They found the HUFA ratio could be more greatly controlled and thus allowing them a greater yield. There is some other very interesting things they've found out via their intensive IA/rotifer research, but due to the major competitiveness of 1/2 billion dollar companies we'll never see it until someone else discovers it. With out risking a lawsuit I'd loose, let's just say there's more to rotifers then what is in their gut. If you can get more of those on the rotifer, your going to see better results. I'm sure some of what they've found is transferable to MO/clownfish breeding, escpecially in this case.

Chucks not using IA. If Im hearing right IA is a paste you can buy right? Chuck's using the liquids from Reed's but not the paste. I've seen his tank many times, its actually my old tank I sold to him. The dendros I have are frags from his amazing tank.
Thanks again

I have never used Roti-Rich but I believe it is a cheap way for mass culturing of rotifers but it does not enrich the rotifers enough to actually raise clownfish. Rots raised on roti rich would have to be enriched for 24 hrs prior to feeding to the Larvae.

I also use instant algae from reeds.

Nope, IA Shellfish Diet is what he is using. Most call it a paste but it is on the more liquidy side. Having packed his shipment myself as well as read his posts on the subject, I'm 100% certain of this :lol:

I was confused, I didn't know it was called IA, just thought it was Phyto feast or shell fish diet. I was 100% sure what he was using just didn't know the product had so many names

just an update. 2 nights ago i had a spawn that was ready to hatch. i only had about 20 fry hatch in the fry tank ( i messed up and pulled the pot a day early.. long story). but anyways, i have only put rotifers in the fry tank with no Roti-Rich and 2 days later all but 1 fry is still alive. this is good news.

how often are you guys doing water changes in the fry tank. and also are you making up fresh SW or are you useing broodstock water for the water change.

There are many IA's, they are all used for different applications. I maintain my roti cultures with nannochloropsis, and enrich the roti's with Isochrysis. I started the roti culture because I have several pairs of northern erectus, and bbs are too large for the fry. I am raising my first batch of SI perculas ( six days old today ), and the roti's were just right for them. IA is fine for culturing roti's but not for green water applications, because it breaks down and adds to the ammonia problem in the rearing tank. Whereas, live phyto will be absorbed and not contribute to ammonia toxification.

Would DT's be a good phyto for the green water, or would I be going through so much of it that it would not be cost effective? I tried using IA in my rearing tank before seeing this thread and that was a complete failure, 100% fatality rate.

DT's or any live phyto culture will work, just do a search on culturing it do determine how much you'll need.
