Crystal Red Shrimps

Hi guys,
I am new with shrimps keeping.
I would like to ask if any bro out there manage to keep CRs without having the use of a chiller?
Thanks!

I would think quite a number of us do keep CRS without chillers... but with some other way to keep the tank cool. ie. Air-con room or fan.

I use a fan on my CRS tank and the water is between 23-26C. This is in a cooler part of the house. I have other fan-cooled tanks which are ranging from 25-27C... I have had some trouble keeping CRS in those tanks but may not be due to temperature alone. I tend to get deaths after they berry and the shrimplets mortality is not very good as well.

your water perimeters are equally important... check your GH. i had my CRS dying on me due to high GH water

yap can keep crs without chiller however this applies to lower grades such as C to A grades, for S grade and above its a must for a chiller.

i kept crs without a chiller before... however they only started to breed when the chiller was introduced.

Yes I think somehow CRS can manage to survive below 28C, a setup without chiller. However, when it comes to breeding, optimised temperature like 25-26C is still required. I started to see my CRS berried and delivered only after my setup with chiller. During the time when my temperature is kept at 28C without a chiller, one or two berried, but I have never seen any shrimplet. Most probably none of them can survive after the female delivered.

if you are investing S grade and above is best for you to get a chiller.
if you are investing on low grade, you can just use a fan.

( Just Like Rich people use aircon,
poor people use fan )

2nd that. grade A to C can breed w/o chiller, a fan will do. I used to have a 1ft tank running with just fan and from 2 CRS, which happened to be male and female, the population grows to over 100 in one year. water parameter control is important too.

Oh... interesting to know!
I guess your tank temperature would be around 28'C?

[Crystal Red Shrimp]

i think the most important thing is where you place your tank , i place my tank in my corner where sunlight cant reach the tank and with a fan i can achieve 25 degree to 26 degree.

If you are using fans and managed to keep the temperature at below 27 the most, B and C grade CRS may berried but the survival rate of your shrimplets may be low. But if your room is an air-con room on for 24hours daily, the tank is kept below 26 degree C, then that won't be a problem for you.

Try to invest in a chiller if you are serious in CRS keeping.

Keeping CRS is no joke. Expensive hobby. Lots of up and down on me since i started about 18months ago. I have already given up on them. Everyday staring at the thermometer hoping to lower the temperature with all means. The worst was trying to run on fan and still see hino dying after you got back from your tired work. Really heart pain.

by using a fan, rather than a chiller, are we able to confirm that the fluctuations of the temperature is not much using a fan? too much fluctuations can be fatal. So far, only chiller can maintain a range of 1 to 2C. When u said ur fan setup achieves 25C and below, what is the temperature throughout the day when it is hotter in the day and cooler in the night? Not much fluctuations?

[dankoo]

For me, using fan, I get cooler temp in the day when the fan is on and higher temp in the night when the fan is off...thinking that I should keep it on throughout.

I used to have a 1.5 feet tank. It is located by the window ( better air flow ). i cool it using fan but the shrimps didn't make it. I guess its because of the fluctuations of the temperature between night and day ( maybe didn't control the water perimeter well too).

I gave up on the 1.5 feet and move on to a 2feet x 1 x 1.5 tank using Ehiem 2222 and resun CL280. Now there has been no casualty ( execpt for 1 largest CRS, i guess died of old age.) I found out one of the S grade CRS got bellied last night. I think i'm on the right track now.

Great choice! Good luck and hope u see shrimplet soon.
