Temperature not constant

[shafique2511]

Sorry if wrong section..don't know where to post..I want to ask.. I put my aquarium in my room and at night I on my aircond from 1am to 1pm  at 24°c..is it ok for the shrimp..btw i live at malaysia

That should be ok. It will vary depending on the type of shrimps as Bee shrimp aren't as resilient as cherry but that is a few degrees below any upper limits! I kept bee at 23 and currently keep cherry at 25 (alow for reliability of equiipment though)! You don't want the temperature to fluctuate too much either so in a high temperature region you will need tto keep it a bit higher as you don't want the temperature to fluctuate between air con off/on periods too much either!

I keep bee shrimp..as you said need to keep abit higher so what temperature you recommend so not fluctuate to much..

I think you are probably about right but it depends to a large extent on what the temperature will be normally during the periods the aircon is off and use that as a startig point so that (within the acceptable range) the tank stays as steady as possible. Obviously everywhere in the world the temperature does change between night/day and season etc.

Here in the UK we probably have the opposite problem to you and use heaters to keep the temperature as steady as we can in our aquariums. My fish tank for instance is 25degrees but in the winter over night it can even get below 10 indoors (an extremely old house) so you don't want that type of swing.

I doubt your temperature varies too much indoors (?) and assume you are comfortable with the 24degrees, so as long as the temperature the other 12 hours doesn't vary much from that, and indoors that is unlikely I would stick with it. If I assume that indoors is normally 20 (?) when the aircon is off you should be fine and could turn the temperature down a degree or 2, but you need to feel comfortable as well of coarse and it will cost more to run the aircon the lower the temperature - 22 or 23 degrees is optimum balance. The higher the temperature the shorter the shrimp live as it speeds up their metabolism but they breed more as well? Maximum for the shrimp should be about 27-28 then they are likely to start having problems coping, cherries can go up to 30 without a problem. We (rarely) get those high temperatures here and there is a lag involved between water and ambient temperature so even if we get 3-5 hours at 30 degrees in an afternoon (extreme for us) the water temperature won't get near the 30 degrees, but it gets scarily near 28 occasionaly (one or two days last summer).

Here my weather

I'd say, looking at those figures you have the temperature prbably about right but it is more about the indoor temperature. You can assumeit will be 24 when the aircon is on of  coarse but what happens when that goes off, do you feel it gets colder or warmer or is it quite consistant ,

The easiest thing to do is get a thermometer and test the tank during a 24 hour cycle, or get one of those stick on the tank ones which make it easier, like this one, very cheap and you should be able to get one easiliy localy I would think,

It may not be laboratory accurate but gives a rough idea of how it is fluctuating without keep doing it all manually.

Thanks Simon..I will buy thermometer
