    I'm planning to start a 5 gallon aquarium in my bedroom. My concern would be the temperature fluctuation as i turn on the air conditioner at night. During the day my room will reach about 30 degree max and a minimum of 25 degree when the air conditioner is turned on. if there is any fish or shrimp that can handle those temperature please recommend me some. Thanks !!

    Would betta or CRS be fine with those temperature change ?

    Not really. Bettas dont do well in cold water but thrive in warm water. Their natural habitat is in the flooded rice paddy fields. CRS on the other hand, is the direct opposite of bettas. They do well in temperatures below 25 degrees celcius. The change in temperature will be stressful to them.

    If you really want to keep CRS, or any other dwarf shrimps, look for local home breeders who keep and breed them in the same temperature setting as yours for a long time. This way the shrimps are already accustomed to the temp fluctuations and have already graduated from commando school. Those that you get from your LFS, 95% of the time, they are not gonna make it. CRS belongs to the Caridina species and they are more picky about the water parameters. Neo Caridina like your red cherry shrimps are more forgiving, but they generally dont do well in warmer waters. If you are a beginner, best not to start off with Caridinas. Experiment and understand more before going into it.

    Another fish that is close to the temperature setting you want is Ember Tetras and they are a schooling fish. They look nice in a group.

    I assume you are not going the high tech route. You can google around for the Diana Wlastad method. She uses potting soil, but you have to be careful on which soil you choose and theres a whole bunch of plants that she recommends. I can only think of rotala rotundifolia, java fern, water wisteria, amazon sword, coontail.

    Intermediate plants, if you get them right, pogostemon erectus and reineckii mini are nice. These 2 can grow nicely if you do your research and prepare well in a Walstad tank. Easy if they are done in a high tech tank.

    Side note, if you take guppies, note that they breed very very fast. If breeding is not your thing, like taking care of 20 to 50 fries at a time, then get all males. If you wanna try breeding, then its 3 females to 1 male ratio. More males than females will stress the females to death.

    Thanks for the detailed ans jetxx. Would it be a good idea for me to add a heater to my aquarium ? For the plants & guppies you recommend or they will do just fine on those 25-30 temp.

    Re: fish or shrimp recommendation

    Ah ic. Then same country. You can lookup glassbox aquarium on facebook. It's one stop shop for everything you need including liquid bacteria for kick starting the cycling process. You can also ask him for recommendations for beginner tank plants in tissue culture cups, a bit costly but you wont have any hitch hikers of snails, worms or algae. He'll also be able to teach you how to start your tank if you ask.

    Live stock can't be sold at the moment so now it's a good chance to start your planting and cycling process first before adding in live stock. They do delivery to your door step. You can say you are recommended by Jun Yan. If you need help or have more questions, just ask any of us.

    Re: fish or shrimp recommendation

    i've looked up glassbox aquarium faecbook and saw the seachem products. Do you believe that seachem stability & seachem prime really works & i can straight up add in livestocks ?

    Re: fish or shrimp recommendation

    When you do water change, and you dose prime, yes you can use it immediately. As for stability, I dont think the bacteria will activate so fast and house themselves in a day.

    Usually the process will be this:
    1) Plant and flood your tank and run the filter
    2) Pour in the bacteria and observe
    3) Third day test your water for ammonia, nitrite and nitrate. Keep testing until you see some ammonia levels. Then that's when your water cycle will start.

    Cycling process:
    Stage 1)
    Beneficial Bacteria (BB) will start consuming the ammonia and colonize your filter media, substrate or anything porous with water flow. At some point, usually in the first week, you'd see your ammonia at peak level and some nitrites will show. That's when stage 2 starts.

    Stage 2)
    As your BB consumes the ammonia, it will produce nitrites. When you test the water and see some nitrites, its onto stage 2. Both ammonia and nitrite will be showing up in your test and maybe on the 2nd or 3rd week, you'd see your ammonia level lowered, nitrite peak and nitrates will show. And stage 3 starts.

    Stage 3)
    Your BB will continue to consume ammonia and nitrite. Nitrifiying bacteria will consume the Nitrite and produce nitrate. At about 4th week or so, you should have 0 ammonia, some nitrite and loads of nitrate.

    You can google around for the nitrogen cycle. What I've told you is just a summary and based off experience using liquid BB, but not seachem.

    A good link that I've read when I first started the hobby on the nitrogen cycle:

    By the way, you can also consider replacing your activated carbon with seachem matrix. Activated carbon usually needs to be replaced every month or so, depending on your bio load. Once activated carbon is saturated, it will start to leech whatever poison it has taken in back into the water. So if you forget and keep using it, your tank will suffer. I usually use activated carbon to remove medication after treatment or when theres an uncontrolled spike.

    Re: fish or shrimp recommendation

    No worries. I'm just curious and I have a lot of time on hand. Hahaha what plants did you choose and what's the substrate you bought? You can just throw in a few fish flakes and let it decompose for ammonia. How big is your tank and which brand of BB you bought,

    Re: fish or shrimp recommendation

    I got myself a 5 gallon tank with tropica aquarium soil as substrate. For the plants that would be Vallisneria Americana, Ludwigia Plaustris, Rotala Rotundifolia Green, Hornwort & Monte Carlo. Lastly for the BB i got myself some Seachem Prime & Seachem Stability.

    i have another question which is will the plants survive without fishes provding them with co2?

    Re: fish or shrimp recommendation

    Icic good choices. For fishless cycling, you need some fish food to provide the ammonia. Fish producing co2 is very minuscule. For low tech tanks, usually they rely on co2 diffusing through the air into the water. So lighting control is very important.

    You can look into Diana Walstad on that. Her tanks are all mimicking the natural state so there are no ferts and no co2. Just using fish waste to balance the nutrients the plant needs in conjunction with lighting control for plant growth.

    She also touched on siesta light schedule, in a non co2 injected tank, where you switch on the lights for about 3 hours, and off for 4 hours and another 3 hours.

    In a low tech tank set up, she found out that the co2 will bottom out in about 3 hours. So anything more than that is not going to benefit the plants and encourage algae growth. And about 4 to 5 hours for the co2 to replenish naturally in the tank.

    Thanks again for the new information. It helps alot Do you have any algae eating snails that you can recommend that can handle the 25-30 degree temperature fluctuation?
