Dying Shrimp :(

[VL1990]

Hi guys, I started a shrimp tank about a month ago (cycled before I added shrimp). I think its around 15litres. I started with 20 cherrys 2 tigers 2 yellow. Everything was fine I was doing weekly water changes my berried cherry had babies etc, then gradually they started dying one by one. I havent had a nitrite spike because hoth nitrite and nitrate have always been 0.nmy readings are as follows
ph 6.8
khmg/l 180
ghmg/l 200
nitrate 0
nitfite 0
The only thing thats been playing on my mind is the temperature it fluctuates from 27 to 24 depending on outside temperature could this be the problem? Also what should I do with the remainder of shrimp (around 5 left) doni remove ghem immediately to my very stable thriving fish tank until my shrimp tank is safe again? Baring in mind I do have large amanos and a frog in there?

Thank you so much for advice. Ps iv added a picture of the tank incase you spot any visual problems.

Hmm, shrimps into a new tank can happen like this. Shrimps will do much better in an established tank as water parameters tend to be more steady and settled down. 
 
You suggestion of moving shrimps to your other tank that contains a frog, assuming its an ADF or similar, these ADF will eat small shrimps really so not the best bet.
 
I'd leave your shrimps where they are in current and hope over the next few weeks they will adapt to your new tank as it slowly establishes.Its possible you may lose them, yellow shrimps are a variant of RCS and sometimes are more sensitive to water parameters, same goes for Tiger shrimps. RCS are basically the cheapest and hardiest shrimps around so maybe gat a few more of these to try and establish your tank a little quicker maybe.
 
Also your heater fluctuations will not help, try to get this sorted and to stay at steady temp of 22 to 24C, not too high a temp otherwise this will basically shorten the shrimps lives. I know you said tis depends on outside temperature but a decent heater should be able to deal with this do within a degree or two either way at most.
 
Those are all just suggestions, not based upon any evidence /facts or anything like that, its just basically what I would try and do myself. Hope it works out.

I would agree that it's the temperature variation that is causing it. A thermostatically controlled heater should sort the problem.

Definitely a temp issue.. First off 24 is a little hot, what is that somethang like 85F?? Lower the temp to aboot 73F and you should be fine.. Also watch the temp of the water you add during a water change.. Match it as best as possible to the water temp already in the tank
