Mandarins are not like most fish we keep. Their digestive system is more like a seahorse or pipefish. They don't have a real stomach and can not store food as we, and most fish can. You can tell how often a fish has to eat by the size of it's mouth. A mandarin has a tiny mouth which is not designed to take a big mouthful of anything at any one time. They are also not designed to bite pieces off larger food items.
A mandarin was designed to eat pods and little else. We as aquarists tend to call anything alive, that we can't hardly see, a pod, but there are actual "pods". Pod is short for copepod but for our purposes we can call any small creature a pod.
Many animals in the sea were once pod size, and the young of almost everything we commonly keep in a tank, that hatched from an egg was a "pod" at the beginning of it's life. Of course if you keep Manta Rays or duck billed platypusses that does not apply. Well platypusses are a fresh water animal and they do lay eggs, (I think) and I know real ducks lay eggs but that is for a different thread.
Virtually all of the crustaceans we keep lay eggs but most of them hang on to the parent until they hatch, sort of the way Paris Hilton's dog hangs on to her.
But I digress. We all know that some mandarins will eat pellets and other commercial foods but this does not mean we can change the way it digests food. The short tube it has instead of a stomach has very little capacity to store food so it will get some energy from that meal but then be hungry for the rest of the day. A mandarin is an animal that was built to eat a "pod" every 10 seconds or so. Pods are small and mostly shell so they offer very little nutrition, but that is what that fish needs to eat.
To me, a mandarin is the easiest, least maintenance, most resistant to disease fish there is but it is also one of the fish that many people have so much trouble keeping for any length of time. I am not sure how long a mandarin is supposed to live because I am not the God of mandarin's but I have had many dozens of them. I find that they are accident prone and the first fish to find it's way into a powerhead when the screen comes off. They also swim up tubes and get stuck, but they almost never get sick and if you feed them correctly, you can't stop them from spawning.
Just today I saw a post about a guy who wants to keep one in a 5 gallon tank because he saw one in a 2 1/2 gallon tank.
Years ago they used to keep tigers in zoos in 5' cages. It can be done as you can keep a whale shark in a bathtub as long as his head is underwater. I am not sure how long he would live or what you would have to use to clean that bathtub with after it dies, but again, that is for another thread.
If you are the type of person that keeps a sterile, spotless tank, who goes to church to pray if you see a little algae or if you personally know Miss Hilton, then a mandarin may not be the ideal fish for you. Yes, you can keep one in that type of tank but that fish should live at least ten years and I can guarantee you it will not in a 5 gallon tank.
There will just not be enough real estate to grow enough pods, it is simple math.
You can of course teach it to eat pellets and throw one in there every ten seconds but sometimes your girlfriend may want to go out to dinner and have a nice glass of merlot.
In my tank there are plenty of pods and God knows what else so I can keep a pair of mandarins, scooter bleeny and some tiny pipefish that all eat pods, but I don't just want them to live, I want them to spawn, Why you ask? Because spawning fish are in the best condition, and if the fish is spawning it is extreamly resistant to "all" diseases and should live past it's normal lifespan.
There is a way to get a mandarin in this condition but it takes a little work and about $2.00 a month.
Luckily for us (and mandarins) brine shrimp are very easy to hatch and very cheap. A mandarin doesn't know a baby brine shrimp from a real Pod, and I think new born shrimp are vastly healthier. The reason they are healthier is because a real "pod" is an adult animal but a new born shrimp (or newborn anything) is mostly oil. A shrimp is born with a huge yock sack which is all oil. Oil has many times more potential energy than meat which is mostly protein. So for every baby shrimp a mandarin eats, it gets more energy. If you don't believe me, start a thread of your own and call it "Paul B is a crack pot and doesn't know a pod from a duckbilled platypus".
I don't keep platypusses, but at one time they were my favorite animal and I went looking for them in Australia. (I didn't find any but found something else, which is also for another thread)
Anyway back to baby brine shrimp. The problem with baby brine shrimp is that for some reason they like to have a tan so they are attracted to light, sort of like Paris. But the light always comes from above so they head to the surface.
Mandarins are attracted to pods and stay on the bottom. To remedy this, I built a baby brine shrimp feeder that is a simple device to keep the mandarin well fed by gradually distributing the shrimp near the mandarin. This is a simple plastic container with a fine mesh over it and a tube going to the surface. Every morning I pour new born brine shrimp into the funnel at the top of the tube and the pair of mandarins, scooter bleenies, pipefish and manta ray fry spend most of the day hanging out on ther mesh sucking shrimp through. When the shrimp are finished the fish go about hunting pods, but on every trip around the 6' long tank, they always visit the feeder to see if there is anything left.
As I said, it is simple to keep mandarins if you don't have a new, sterile or small tank but if you suppliment their diet "every day" with new born brine shrimp, they will live forever and if you have a pair, they will spawn almost every month.
I hatch shrimp every day in a shrimp hatchery and egg seperator, I don't know if they sell these but they are simple to make.
These are just thoughts and I hope it helps with mandarins or possably for the few that may want to try their hands with manta rays.
Here they are spawning

Thank you for the great idea Paul! I did not know they were readily eating Artemia nauplies!

Regarding the egg separators, if you want to simplify your life and make your culture more resilient, you should look into decapsulating the eggs, or buying already decapsulated eggs. I do that for my dwarf seahorses since I do not like the smell of bleach and it is pretty cheap anyway. (www.brineshrimpdirect.com/ carries large quantities)

It is just a container with a fine mesh over it. I used an old net. The container I used for this one is something that electrical tape came in but any flat container will work. At the top of the tube I have a small funnel where I pour the shrimp with a little water.
The shrimp last about 2 hours until they eat all of them but I have a lot of fish that enjoy them.

Many of the fish enjoy the feeder but I made it mainly for the mandarins.
Here is another video with the copperband, mandarin, pipefish and scooter bleeny


Here is the hatchery and egg seperator. I put eggs on the right side every day and then cover it. Then I slide open the door between the two sides and they swim toward the light on the left side. I open the valve and only shrimp come out.
You can decapsulate the eggs if you like but I find this very easy and have been doing it for over fifty years.

I guess that would work. My thing is very simple, it is just a dark container with a divider and a hole in it with a way to close the hole. I am not sure how much energy a shrimp expends hatching, but I never thought about it.
But I make everything and I wrongly assume everybody did.
If I was stranded on a desert Island, I would build a flat screen TV out of a coconut, and if it was a really good coconut, it would be HD

thats a beautiful pair of mandarins. i like your feeder idea, just have a question, if the feeder is on the bottom, and funnel is on the surface, how do you get shrimp to the bottom?

lmao Paul your post are always so informative & hilarious.

Regarding your feeder, ever think of making one and selling it? I would buy one since I'm as DIY inclined as Paris Hilton is not being a street walker :x.

A lot of people ask me that. After I collect the shrimp and water from my hatchery, I strain then through a baby brine shrimp strainer that you can get from Florida Aqua Farms as a rotifer strainer. I think they also sell a net for that. Then I put a little water, maybe a tablespoon of water with a baster through the net backwards to collect the shrimp. So now I have the shrimp in a little water, I dump that into the funnel. You can't pour the entire pint of water from the hatchery through the funnel or most of the shrimp will be pushed through the mesh.

No, I already have two patents and still sell one item. That is enough of a pain so I am finished selling anything. You can build the thing in about 2 minutes no matter how DIY handicapped you are. Get a plastic container, put a net over it with a rubber band, drill or melt a hole in the side and find a tube to stich in there. Home Depot sells a black or gray PVC tube the right size, it is used to connect bathroom sinks and is about 2 bucks.

You offering to hatch them for me so all I need to do its get them from you? ;)

I guess you already know the answer to that one also. :eek:rangehat

The original design for this feeder was my patented seahorse feeder that worked with adult brine shrimp. http://breedersregistry.org/Articles/v4_i3_paul_b/paul_b.htm

Just something to add...womens pantyhose or nylons work great as a brine shrimp net. Also if you want to be even cheaper go to a womens shoe store and grab a few of the free nylon socks they have out for women trying on shoes.
