Third attempt raising clownfish...

Luis, David,

Using a OR 6500 should give me enuff water flow I hope. I will create a loop that the pump feeds so there are no dead ends so to speak.

I am thinging of a similar setup to a shop setup.

Pam, if you have trouble finding that link let me know and I will locate it for you. There are several places that I she has posted.

Or using an extra wide delivery line as David says,in this case that pipe is the manifold.

Yes, that is exactly how you do it, and it does work. Under pressure from a pump if you close one valve you will increase flow to every other tank, just like a gang valve on an airpump. With the gravity system you can shut off or limit any tank without changing anything else (maybe very slightly but not consequential). My point above was that it's fine for low flow applications but impracticle if you want to push a lot of water through the tanks.

I have a 1-1/2" feed with (5) 1/2" taps feeding one rack and it works great, but the 1" feed with (6) taps can't hold enough water so I had to put a pump on it.

Not trying to argue but I do actually like the design, just have to size it right.

Kathy,

My thought was to use water from my main system diluted with fresh RO water to start the process in 2 five gallon buckets. Would I then harvest a gallon out of each bucket daily and replace with more diluted tank water. I imagine that the food that I purchase will be quite a bit more concentrated than what you're making.

sounds like a plan. Depending on their concentration, you may not need 2 gallons daily. You only need to grow 4 times what you need each day, to harvest 25% (which I've heard is a good harvet rate to keep them from crashing.).

I'm wondering if there might be a market in the Atlanta area for selling the rots that I harvest.

I don't know, I don't sell them. They have a very short shelf life, though, if you want them to be live.

How would you know how many you have (can you see them) and how much to used in tanks for feeding?

How young are you? If you are over 40 as I am, you can't see them unless they are in high concentration and there is sufficient light. I have a microscope and a pipet. I count how many rotifers are in 0.1 ml rot soup, and multiply by 10 and that is how many rots per ml that I have.

For clownfish, one starts with 10-15 rots /ml in the larval tank, and I don't know what it is for dottybacks.

I wish there was a way to raise the babies in my large refugium, if there was a way to keep them separate from the rest of the system. Any ideas? I only have a pistol shrimp w/goby and recently a seahorse in there. It's approx. a 75 gallon tank with low flow and lots of pods and calerpa. The problem would be keeping them separated and feeding them without poluting my tank. If that's not possible, I have a 10 gallon tank that I'm not currently using.

I am afraid I have no helpful ideas or advice. I think you may wish to start a thread of your own to attract the kind of experts you need for this project.

I've read a little of Martin Moe's book and so far it seems quite discouraging. I would love to hear from people that have succeeded with raising orchid dottybacks recently and learn from them what worked.


Yes, me too. Martin did have great success but not at the beginning. He was very analytical and instead of getting discouraged he tried to think of the reason things went south. He learned from each failed attempt. He kept trying and he got there in the end.

I'm sure my 1st batch of eggs were a snack and I may have a new batch by now. I don't want to get too invested in this project and lose hope. I know it won't be easy plus I'm sure it will be time consuming.

Any thoughts?

Pam

Most likely it won't be easy and I'm sure it will be time consuming. Dottybacks may be more difficult to raise than clownfish. I have no experience in either. I think you need a thread of your own to attract the kind of expert help you need to help you succeed. I will be very interested in following your progress. Good luck!
 
David,

Thanks for your response. I understand what you are saying with the size the system correctly and the gravity fed system.

Kathy, how are your rots doing? Have you manage to go beyond the second jug yet?

Thanks

Steve

3.5 gallons today. I could get them to grow faster, but I want to keep the phyto population going for when the eggs hatch. Then I may need a gallon a day of phyto as well as rotifers! The rots will be at 4 gallons, 200/ml, I think, by Thursday when I collect the eggs from my friend's clownfish.

Steve, don't forget to do the bleach/dechlorination on that tank water before you use it to culture rots and phyto!
 
Kathy,

Still trying to find those magic Chlorine test strips here in the UK.
Once I have one of those I will do the math for the amount of bleach and de-chlorinator I need.

Think I have also found a local supplier of Phyto, so should I have any problems I can get more to culture.

Thanks for the info on the rots. I will post a photo of one of the Demi-jons for you over the next couple of days.

Good luck for Thursday. Wil you start a new post or keep this one going?

Steve
 
I picked up the eggs from my friend's house yesterday (Wednesday) evening to prevent the "early hatch in parent tank" problem I had last time. They did not hatch last night. Good.

They should hatch tonight! I have 400000 rotifers enriching for the next 8 hours, so I can feed the fry first thing in the morning. I turned down the bubbles so they won't get killed on the turbulence like the first attempt. We are in a 20 gallon tank, so I can increase the volume later after rotifers. Everything is ready!

I have to be strong to resist the urge to creep downstairs with a flashlight to take a peek!

I've decided I don't need so many rotifers. 2 gallons at 200/ml is twice as much as I need, I've got the 2 jugs going in case one crashes, so I collected the rest of the rots this evening and packed them in the fridge in case of emergency. With 4 gallons, I can't keep up with feeding them without running out of phyto and now I need extra for enriching rots and making the larval tank green. I could use yeast, but that would be more work as I would have to clean jugs more often. So 2 gallons of rots, harvesting 25% per day should keep the fry fed without depleting the phyto bank.

:D
 
Kathy,

Hi there, thanks for the update, did you pick up the eggs yesterday? Hope you did :)

Steve
 
The Hatch !!

The Hatch !!

They hatched last night! There are around a hundred I think! Most are swimmers, some are floor darters. I just added the enriched rots. Still not sure about the light. I put a paper towel over the tank to shade it. And there is greenwater in the tank. Let's hope they start eating!!!!!!

Can you tell I'm a little excited? :bounce1: :bounce3: :bounce2: :dance:
 
Definitely Excited.

This is such good news for you. Keep us posted and how did you enrich the rots?

Steve
 
Mine layed eggs yesterday, I havent made the attempt to aquire them yet, if I did I would leave them for 9 days?

Yes, here are pictures

Yes, here are pictures

Backtracking a little, here are the egg laden tile and incubation pictures. I glued the airbar to the back of the white ceramic tile with silcone aquarium sealant to weight it down and make a space between the air stream and the eggs:

Got Larvae?

Got Larvae?

I have 1-200 of these so far. I haven't found any dead ones, but a couple are doing the psychotic circle dance of death, so it won't be long for them. Still this is SO much better than I ever did before:
