Copepod Population

I have recently gotten my sal****er aquarium up and running. I have a 36
gallon tank with roughly 36 lbs of live rock, and a EcoSystem refugium. I
have noticed hundreds of copepods on the rock, in the water, and on the
sand. How fast will these reproduce? I am interested getting a
Manderin/Psychadelic fish and I have read that the cope's make up a sizeable
part of their diet. Will the population maintain high enough numbers on its
own with the amount of rock included? Thank you for any help.

Perhaps, yes, althought *I'd* increase the LR in order to assure he
won't eventually reduce the population and starve. My spotted
mandarin will not eat anything other than 'pods, although I've heard
from mandarin owners whose fish will accept nearly anything.

Keep a piece of open cell foam like a piece of a pre filter in a refugium
and it will fill up with pods and you can squeeze them out into your tank
from time to time. Otherwise the pod population will be decimated if you
have any other pod eating fish in your main tank

I own a 4 year old reef tank with over 300lbs of LR. I have had a very
difficult time in keeping a mandarin goby for an extended period. IMHO
I think anything less than 75-100lbs of live rock may be too little to
insure adequate food. Of course I have not had success, and perhaps
there are others who have had long term success with small tanks.

But you haven't even had success with 300lbs of LR, so on what basis do you
conclude that 75lbs isn't enough?

I've got a 55gal tank with about 60lbs of live rock. I did lose a mandarin
that I added far too early, but after a year or so my tank was mature enough.
I've had my current mandarin for about a year and a half. It doesn't eat
anything that I feed into the tank, but it seems fat and happy just snacking
on the live pods it can find in the rocks.

My point is that Mandarin Gobies are known to be difficult fish to keep
long-term. Even when there should be more than adequate food supply
such as in the case of my tank with over 300lbs. 60 or 75 lbs may be
adequate, but I think many would agree that this is only adequate. Any
competing feeders such as a wrasse, and the food supply may quickly be
inadequate. The poster requested input from others, and I gave mine
for what it is worth. I applaud others who have had more success than
I, and hope to educate myself from others successes and failures.

A refugium will definitely help. When you choose your fish from the
LFS, try to get one that eats prepared foods. Call the LFS ahead of
time to find out when feeding time is and be there. Explain to them
that you want to make sure you get one that is eating prepared foods.
Also don't take one that is emaciated whether it is eating or not. If
it's sides are caved or sunken in at all. The fishes sides should be
very full and round. When the madarin turns its sides should almost
have fat bulges.

And be sure to see the link entitled "mandarin diner" at the bottom of
the page.

The pod population in my 125 ebbs and grows.....a mandarin requires a
continuing supply and IMO, 36# is a 36 gallon might not sustain him
long...especially if other predators like starfish of the sand sifting
variety are present. I believe ISPF has a pod growing set-up that you can
order to cultivate them for fish like the mandarin...
