- What time do you have with the CRS?

I started to keep CRS since Dec 2007.

Let's begin for the values of the water:

- What you value will you say that are the ideal ones for the CRS?

Ans) My tank normally :

pH 6.7
GH 6 - 8
KH 1 ~ 3
TDS 290 ~ 400
NO3 <5ppm> NO2 -> NO3 normally No3 is low they other 2 should be fine.
if suddently introduce large amount CRS to tank, the water parameter would change. or Any odd of CRS death Check NH3,4 and NO2.
NH3,4, NO2 should be 0 . and NO3 should under 25ppm
KH is not a big deal.

The Water has to be clean water, like drinking water, RO water. around 10-40 TDS.

- To keep these values like that, what filtering material uses?

Ans)

I would choose high Biological media since Biological filtration is a long run.
I would choose acidic bio media to keep the tank acidic, eg. Totto media, ph House. One more Eheim Substact pro doesn't affect pH much.
I am using Eheim, and Totto media.

- What type of filtration advises (interior, exterior( filter, of bottom ...)?

Ans)

Many breeder love to use part UGF.

My choice is Exterior + UGF.

- What substrat do you use in yours aquariums?

Ans)

A good substact also is vital to CRS. I use ADA I Amazionia.

- What size of aquarium advises you to raise CRS?

Ans)

I will choose 20gallon 2 feet or under, easier to setting up again after a year or later. 10 gallon and 20gallon to start CRS is much more easier than start CRS in 5 gallon in my experiences.
Larger size may be hard to re-setup.

As for the feeding...

- What food do you prefer? Arrange the following ones of better to worse: hayashi, biomax, mosura, shirakura, ebi - ten, ebikuma, benibachi.

Ans)

I use mix food. spirulina power, normal CRS food.

every food is different, may be the best choice is feeding different one each day.
I special like G10 for small shrimplets and left to 2nd's for big CRS.

- What every all the time realize water changes? What percentage?

Ans)

- What do you think about the new mutations of the CRS?

Ans)

In my opinion, the original CRS is still the main stream. and a CRS can improve
the color, shell, pattern from the breeder.
Mutant probably is another kind of blood line like CRS. or a tool to improve CRS. but if using mutant breed back CRS, may have a risk or lowering the grade or the offspring. like Golden white shrimp (mostly would lowering the whitness of CRS) but using top grade GWS - snowwhite may get a higher grade offspring.

- Do you add to the water some type of chemical complement? (Minerals, bacteria ...)

Ans)

I add variety bacteria. Hagen has two : 1) red cap, 2) white cap. Using 3-4 Japanese CRS breeders (one is from EBI-ten) bacteria. An glass tube bacteria from Europe for emergecy or high No3 use.

- What function have the little red stones that you supports in your aquarium? http://i305.photobucket.com/albums/nn203/kelvin2go/1st_tank/082008update/whiteBody1.jpg

Ans)

The stone from above link are for decoration only.
However, the grey stone from this picture
http://i305.photobucket.com/albums/nn203/kelvin2go/1st_tank/082008update/whiteBody2.jpg

That is EBI-Ten Old Sea mud stone.
- provide many materials
- stable pH
- helps to absolve bad substance.
- brush it back to grey stone to renew.

- Why do you put groups of different CRS in cut bottles?

Ans)
I put them in a bottles for selling. sometime grading is different in different people minds. I shoot a group of CRS and sell as what the picture show.
