    Are there any bottom dwelling fish species that can live happily in an unheated aquarium that is usually around 15 degrees C or 59 degrees F in winter and around higher than 20 degrees C or 68 degrees F in summer? My tank is about 15 gallons or 56 Litres and its  dimensions are 22″ or 56 cm in length, 10″ or 26 cm in width and 14″ or 36 cm high. It is a planted aquarium and I plan to plant alot of vegetation, java moss, anubius, a feathery plant I don’t know the name of, and possibly java fern. The substrate is pea sized gravel and a small amount of aquarium soil where I will plant my plants. The filter is a built in power filter in the hood, moderate lighting, and two air stones. I am planning to keep white cloud mountain minnows, and if i can find them Japanese ricefish and rosy red/fathead minnows. Also please suggest other fish that I could keep. I could afford one or two small low energy heater(s) to help heat the water in my aquarium a few degrees warmer, but after a heater incident a few years ago, I’m trying to avoid heaters.

    The Hillstream loaches in the genus Beaufortia come to mind temperature-wise.  They require good water flow though.  There are three species in the SF Knowledge Base.  I know nothing of the ricefish or minnows, so cannot say if these all work together or may have issues respecting the water movement and behaviours.

    I’ve heard of them, but I don’t think they can survive in my unheated aquarium at winter, also it would be hard creating a strong single direction current in my aquarium as it is quite small, causing allot of water to ricochet off the other side of the tank, thanks for your help though.

    P.S: I actually spent allot of time researching Hillstream loaches before.Laugh

    Fathead and white cloud minnows come from fast flowing water too.

    But I don’t think rice fish do, they come from slow moving or still water like rice paddies, though they are a hardy fish and can live in moderate current, but not too fast. Also rice fish will thrive better in brackish water compared to freshwater. They can also survive under the cover of ice with no detrimental effects to their health.

    I’m also thinking of getting cold water variety pacific blue eyes,  they come from fast flowing streams in Australia.

    Also I might get some rosy barbs.

    My only comment now would be tank size.  A 15g is not sufficient for Rosy Barbs.  The other fish appear to be relatively small, but you may be at or close to the tank’s limit now.  Again, my unfamiliarity with the behaviours of some of these fish prevents me from offering anything more precise, my apology for that, but I would be careful not to over-populate such a small space.

    yeah, I just researched that….

    I’ll try to make sure I have the minimum number of each species of fish.

    All these fish are schooling species, and I know that there is a minimum of 5 white clouds, 8 pacific blue eyes. I’m not sure about Ricefish though.

    I’m thinking of keeping ghost shrimp as a bottom dweller instead.

    Thanks for your help!

    also I’m not going to keep fathead/rosy red minnows as they will grow much larger than the other fish, and will therefore eat the shrimp.

    This will also reduce the bio-load of the aquarium. I can’t find the fathead minnows in any of my LFS’s either. The other fish I plan to keep can be found in my LFS’s.

     

    Thanks for the help!!Cool

    I just read there is more than one species of hillstream loach, and not all of them have the same requirements. The butterfly loach will do well in a unheated tank at where I live, but a tiger hillstream loach won’t. But my aquarium is too small to install powerheads to blast the water, so I still won’t be keeping them. I have found many other fastwater species that can be kept in an unheated tank, but my aquarium is just too small to allow for high flow rate.Confused
