Copepods, you think you know them? well in this show im joined by Dr. Adelaide Rhodes, a world recognized expert on Copepods. Adelaide will take us though the in's and out's of copepods and what they mean to out tanks today, and in the future.
In this show we discuss
- What are copepods
- Identifying copepods
- What are copepods good for
- How to get copepods in your system
- Breeding copepods in and out of your tank
- And much more
Gosh, I can't wait for this to finish downloading. I've enjoyed reading her website and have thought she would be a really interesting guest on the show.
Excellent show. Adelaide was a fantastic guest, with lots of great information. I plan on visiting her site next, if I can ever get off this one! I agree with Veriann - these are my favorite types of shows.

awesome, yes, make sure you check out her site, great stuff.. OceanPods
im glad you enjoyed it..
Adelaide was a great guest, and has agreed to do future shows if the listeners want.. just think up some questions and let us know

Great show Rob and informative as usual. It was good to hear from Adelaide as I purchased a bottle of Oceanpods about a month ago and placed them in my tank a few weeks before putting in my clowns. I was very skeptical when first receiving the bottle. I honestly only saw a few copepods swimming around the bottle. I could not believe it a few weeks later when I inspected the tank in the middle of the night to see more than I can count on the glass. I wish I had a refugium, but even without on I still have noticed that these little guys(Harpacticoid copepods) have multiplied big time. At night I can see a bunch of them mostly on the glass in the corners of the tank. I thought it was interesting that she mentioned keeping a bit of the glass with some algae as from experience these little guys flock to these areas of the tank. I will take her advice and stop cleaning at least a partial section of glass for them. When I look on the rocks, I rarely see them but I will pick one out from time to time. I am wondering if this has something to do with current in the tank. I have 25-30x turnover going on and I rarely see them anywhere but the glass.
Some LFS's have been selling an alternative copepod(Tigerpods - Tigriopus californicus). Not sure about the benefits of these little guys in our aquariums. What I have noticed is that the Tigerpods are much larger than the Oceanpods. The Oceanpods are really tiny.
I set up a mini refugium with sand(I guess not a good idea) to start culturing some Tigerpods. I think I will try the 1 G Rubbermaid method as it seems the current 5g refugium idea is going to be impossible to get them out. I am really interested in culturing these little guys. It is great to see these products out there these days as like it was said in the show, the mandarins really need these little guys to survive.
At the moment I have a couple questions regarding copepods in general:
1. In noticing Oceanpods mostly on the glass, would high water turnover(20-40x) effect the production of these little buggers in the aquarium?
2. In such a large system(our aquariums) in comparison to the size of these little guys, can someone explain how it is possible for such a small amount of live phytoplankton to be taken in by these little guys? I guess what I am getting at is if I am not seeing them much around the rocks and mostly on the glass, how are they getting to the phytoplankton if it is in the water column? I am turning off my skimmer for an hour after dosing phytoplankton.
Thanks again for the info, Rob. Can't wait to hear a few more out of the million copepod topics in the future.
Great topic Rob, now I may actually be able figure out what is in my tank. I thought the photo below showed Copepods, but now I don't think they are. I also don't think they are Amphipods, because I have seen the photo of them. So after a little research my educated guess is they are isopods. Maybe sphaeromatid? What do you think?
A litttle history on the photo, sometimes Nori falls out of my clip and gets pulled into the overflow. I usually remove it, but when looking this evening, I saw these buggers all over it.
Whatever they are, they are doing a gereat job at cleanup!
This was a wonderful show man. I was wondering something while listening to it. If copie's are more nutritious than rotifers, might culturing copies be the key to sustaining the fry of other fish species? When we were talking rob, you mentioned that only about 20% of the clown fry survive to adulthood. If you are going to try feeding copies instead, maybe that number will increase. Let us know if you do so.

my answers would be speculative, i will defer to Adelaide on this one

yes, think you are right in that they are isopods.

actually, what i as mentioning is that i had about 20 survive from my last clutch, people that do this more regularly can get hatch rates as much as 95-98% survival, but yes, it does involve properly enriching (gut packing) the rotifers. Copepods do sound like a great alternative food source, one i will be trying in the future
