Paramoecium is a very small Protozoa. It is only just visible to the naked eye and is better viewed using a strong magnifying lens. It moves about the water column, feeding on bacteria, using an arrangement of hair like filaments (cilia) along its body. It is a very good food to have in your killifish larder for feeding to the smaller species fry. These minuscule animalcules are ideal for feeding to fish fry which are too small to accept artemia and microworms as their first food upon hatching from the egg.

Culturing Paramoecium is relatively easy but your vessels need to be maintained on a rotational basis in order to keep the culture going.
In the following article I will show you how I set about culturing this fascinating little creature.

For the most part the items you will need are all available on the high street they are as follows;

Pure Paramoecium starter culture
Square slab sided Mason Jar with French Clip Lid
Small bale of Straw or Hay (pet bedding)
Bicarbonate of Soda
Electric Kettle
Pipettes
Household scissors

Mason Jar...I discarded the French Clip lid and gasket.

First thing you will need is a pure Paramoecium culture, one that is not contaminated with any other protozoans which may feed on the Paramoecium.

Boil a handful of straw in the electric kettle and leave to cool. When it has done so pour about 1.5 ltrs into your glass pickling jars. you will probably find that the amber coloured water is a bit acidic. If it is, you should then counteract this with a little Bicarbonate of Soda to make the pH neutral (7.0)

The next step is to take the boiled straw from the kettle, and with some household scissors snip some 2cms cuttings into your liquid in the jar. 10-12 snips will be adequate.

Finally pour in your starter culture and store in a warm, lit room (but not in direct sunlight).

The culture will take around a week to really be suffused with these tiny little creatures as they feed and sub-divide, but visible signs will be there after a few days as the liquid clears somewhat.

After a period of two weeks it is time to set up a couple of new cultures (sub-divide) as the original one will be starting to wane. At their peak these cultures are absolutely teeming with life, dont take my word for it, try it for yourself.

Note: Do not use the same pipettes for feeding etc, to avoid transferring of liquids from vessel to vessel for fear of contaminating your culture.

Quite a simple and easy protozoa to culture, that if properly maintained will last indefinitely.

Thank you for the replies. I'll start some infusoria right away, but it won't be ready for at least a week right? What do I do in the mean time? Since the X-mass moss hasn't been in my aquarium very long (only 4 days). If I spot any fry, I'll move them (with a baster) to a new container filled with some of my established tank water. Then should I add a little of the moss to the container? What should I feed them (if I did get any to hatch, who knows, maybe the eggs weren't even ready)? When can they take microworms?

Right now my Killiefish have been wet for about 20 and a half hours. I started them yesterday at 3:40pm and it's now 10:50am.

Please tell me what I should do! I don't want to do this wrong.
 
A vase of water that has had cut flowers in should be full of infusoria which should help you along...dont pollute the tubs though
 
Okay, so I'm going to go start some infusoria, using some water from my Betta tank (it has a lot of algae in there, and has been established for quite a while). I'm planning to use lettuce leaves, instead of banana peel (since it has pesticides and I don't want that to harm the fish).

I don't have any fresh flowers in a vase, so I can't use that.

I just looked for hatched Killies again and didn't spot any. I do however see eggs in there still and they look undisturbed (round and not hatched). I did spot what looked like some of them "eyed up", so maybe I just need to wait longer for them to hatch. I'll keep the containers with them floating in the tank for now.

I'm going to add some of my X-mass moss to both of the containers with the eggs, just in case any fish hatched so they won't starve.

How long before I can start feeding fry on microworms? If I see any.
 
leave until tomorrow...if none hatch then follow procedure for re-drying your peat for another week or so
then try again...this will give you ample time to get a micro food culture started

Okay, I'll do that. Thanks for the suggestion!
 
I have a question about snails...

Would it be a good idea to put a snail or two, in my infusoria (mason jar along with the lettuce leaves)? So they could eat the lettuce and make infusoria? If so what type of snail?

I'm considering getting some snails for my Killifish raising trays, (when they hatch)which type should I get and how many should I put in there? Should I also put some in my Betta tank? Or should I wait until I have free swimming fry in there first so the eggs that fall out of the bubble nest don't get eaten by the snails?

Thanks for the help.
 
I use Red Ramshorn snail available from Phil Blackburn at Fish Philosophy
a bit late in the evening...I'll post his address tomorrow
contact him via below address

http://www.fishphilosophy.co.uk/store/
..tell him Colin (BigC) sent you.


One or two snails per tub only...remember they also contribute waste products so waterchange regularly
Not sure about Betta's as I have no knowledge on this subject.

I am not sure about snails making infusoria, but a renowned killifish breeder used apple snails in the fry set-ups to eat any left over food so the water doesn't get contaminated.

Colin, the OP is based in the US... I think it is better for her to find the snails there.

Thank you for the info. I noticed that website is in the UK, so it would probably be better for me to get some snails from some place closer, especially considering the strange weather we've been having here in Montana. The last plants I ordered from a different country froze by the time they got here. :p

I'll keep this in mind though and maybe this Summer I'll need some, and can go to him.

Thanks!

[color="#222222"][font="Verdana]Sorry Eleanor....thank you for pointing out that fact...[/font][/color]
[color="#222222"][font="Verdana]Some research on an endemic or easily acquired (non invasive) small snail would need to be done on behalf of the OP.[/font][/color]

Biulu, what is the "OP"? Sorry, I'm not familiar with some of the terms you guys use on here. :) I raise fish by myself and I'm not part of any club, group, etc. I also don't know any fish hobbyists in town. Most of what I get comes from Walmart (I know not a very good place) and the internet. We have a couple pet stores that sell fish, but no dedicated "Fish store".

So if you can give me any tips on buying some snails, I'd like to get a couple. If anyone on here has extra they want to get rid of, I'd be willing to pay the postage.

Thanks a lot!
 
OP (Original Poster) being yourself.
Try and contact some members of the American Killifish Association (AKA)....(You should join)
But realistically if you are interested in Killifish they will for the most part offer you some valuable information on all aspects of this niche area of the hobby

TBH (to be honest) in your case (infusoria aside) I see no real need for snails.
Do your homework and get a micro food culture going that suits your needs and stick with it.
Look toward biological supply companies and hobbists for your source cultures.
After that you can maintain these with a little care indefinately
