Who has kept CRS without chiller?

[CHOO]

hi just want to check, is there any one keep crystal red shrimp (CRS)without chiller and has breed........

[EvolutionZ]

im keeping my crs in a non chiller but with fan tank..
they have been breeding and i have quite alot shrimplets =)

[bryant_16]

bro evo, whats your constant temp?

[marle]

it is a certainty that some breeders have been able to breed crs with fans.

Question you might us is how? 2 factors. (Lets keep all other stuff like filtration and others out of the picture, all others ceteris paribus.)

With fans, you need to constantly top up the water in your tank due to increasing evaporation rates. The tricky part is to keep your water parameters suitable to your shrimps. If you are able to do so, thats great. Its better to keep a bigger tank at least 1.5ft and above, so the parameters will not change that much compared to a smaller tank when you top up water.

During warmer months, a fan might not lower the temperature enough for successful breeding of crs. Its only in colder months, the process will be easier.

I feel that these 2 points are vital to consider when you want to breed crs with fans.

for this few months.. my tank's temperature has been hovering around 25 - 26C. like what marle say.. when topping up of water. water parameters will change.. i usually use those drip method thingy( i use plastic one as metal always rust on me) and slowly drip aged water back into the tank within 2hours.

hi evo,

how is your temperature like when it is the warmer months?

above 28C?

iin the warmer months, what happen to your CRS? do they just stop spawning or do they die off easier?

Bro, What's your contingency plan for hot weather? Blow more fans?
BTW, what are your CRS grades for your non-chiller CRS tank?

[EvolutionZ]

the max my tank has gone up is 27C.. well.. i do have deaths of crs but still okay..
just yesteday one of my A grade pregnant shrimp die.. i would say using fan is not really stable for crs.. im considering chiller again.

anyway. my grade ranged from B to Hinomaru.. but i only have 2 low hino and a few S grades.. other than that all are A and B..

[stillife]

I read some posting on web that the higher grade you go the more sensitve they are. So if your higher grade CRS casualty numbers starts to go up, you may have to consider creating a better water environment for them

Colorful boss told me best to set 24 degC for CRS. I shall set mine to to that temp range if I'm going Hino range.

Good luck Evo.

cheers!

[EvolutionZ]

yea you are right.. but strangly.. all my crs which died are all B grade big mama.. over 2cm.. perhaps they die due to old age? i bought them 3 - 4months ago at adult age..
good luck to you too

[stillife]

Hmm...perhaps too many male ones? Not enough mamas?

Or too many male ones until the mamas confuse which to mate? Just kidding.... I have zero knowledge on how male shrimp pick their female.

Or like what you said, they could be old liao. I remember I read their lifespan is about 15 months.

I'm now hoping to see my CRS grow and start to mate and breed.

Will put some pics if they are nice.

cheerio!

Just wondering did you guys using fan have a raise in temperature today?

[CHOO]

so is there any hobbist keep without using fan as well, as I see shop selling like C328 never use any chiller, is it grade A,B,C can don't need chiller or fan?

[Lala~]

CHOO, they just keep for sale. Do you think they care if one or two of the shrimps die ?

[EvolutionZ]

Just wondering did you guys using fan have a raise in temperature today?

yes! mine was like 27.5 today! highest ever recorded

[CHOO]

CHOO, they just keep for sale. Do you think they care if one or two of the shrimps die ?

just check is there any does without cold water as electricity is going up trend , thinking whether can do away cold water. I believe shop owner they do care because is directly effect their profit .

Hi,

I'm also breeding CRS at home without chiller, only fan... before then, 70% of my CRS keep alive but cannot breed (temperature was average 29-30 deg).

When i installed two new fans, the temperature stay around 28-29 deg and now breed like rabbits.

[stillife]

Hi Ivan,

What grades of CRS are you keeping and managed to breed? Any pics to showcase your CRS?

[stillife]

Hi Choo,

In my opinion, in order to ensure stability and good growth for the CRS, they should be rear in best conditions suited for them. These conditions derive from veterans and many experience hobbylist or fishfarms.

You may be able to keep them alive without fan or chiller. But can the CRS sustain or live long (chances could be slim).

There are some hobbylist who are able to retain their tank temp below 28 deg as they stay in high floor where the tank is constantly blow by the wind near the window.

Not talking about CRS, i tried keeping cherries at 30 degC but all died after a few days. CRS may not even need to consider.

For C328, the CRS there are meant for sale and they got it from supplier at definitely good and low price. We may not know how many CRS can survive end of the day when they close the shop.

Sustainability is more relevant in order to rear CRS.

Perhaps you can give yourself a chance to try rear CRS w/o Fan. Measure and observe how long they can last with harsh condition.

Hmm....put it in simple analogy, assuming we are thrown into North Pole or Sahara desert, I wonder how long can we sustain these kind of weather.

Ok..have a nice weekend pal!

Cheers!

thank for all kind and experience input from various hobbists.will try CRS if I find that I more ready then.
