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).

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.

      Welcome fellow UK shrimp keeper! I would think it would be better to remove the shrimp into the quarantine tank and keep them there whilst you treat the fish in the main tank and once you finish treating the tank and fish do a complete water change (maybe 2 a week apart for safety) before returning the shrimps. That would seem the best option though obviously the shrimp would need to be in the separate tank for weeks. I'm not aware of any medications available for ICH that won't kill shriimp and/or snails. With neocaridina they probably will just about survive 30 degrees but you are pushing it close to the limit! I don't believe ich affects shrimps.

      Re-posting here from The Shrimp Spot forum as I need help. Help, 40 litre tank has a ich (ichthyophtyirius multifiliis) / white spot outbreak. We've been able to separate the few surviving neon tetra into an emergency quarantine tank, with appropriate medicine for the fish. We had done this as we had noticed the issue practically too late as we miss identified the white spots as cotton mouth (which the tetra also have). We luckily quarantined the fish from the tank as  the ich reached its second stage as most have matured and abandoned the fish. This has become an issue as even if the neon tetra do not survive the treatment, I cannot re-add them to the tank and I don't want to keep the tank's environment full of parasites. Thankfully ich seem to not be able to effect the shrimp but the medicine we have for them is toxic to the shrimp and the plants in the tank, hence the separating of the neon tetra. I was wondering if there was anything I can do to the tank while the shrimp are still in the tank, as removing them isn't a viable option. We've been trying to get the temp of the tank to 30C and leaving it at that temp for an hour, however the tank's heater is verry slow and doesn't seem to be going up past 27C. From what I've searched 30C should kill of the ich without irritating the bloody mary shrimp too much (too many websites vary their recommended temp, so I wouldn't keep it above 28C long if we were able to get it that high) If anyone knows if there are any ich treatments or methods of killing ich that are safe for invertebrates and potentially plants I would love if they could suggest one.

      For beginners and smaller tanks, I recommend glass aquariums because of their affordability and scratch resistance. For larger, more advanced aquariums, we recommend acrylic because it's lighter and easier to repair than glass.

      Hooray! I was hoping it was molt but he hasnt progressed at all in about a week. Thank you guys so much for your help again. Ill keep an eye out.

      It looks like the shrimp is about to moult.  I don't keep Ghost shrimp, so I'm not too familiar with how they look when going into a moult. But the white band along each joint is common in other shrimp when they start to moult.
