I have a new little tank set up in my bedroom, its 25 litres (thats 6.6 gallons :P) and I was originally going to get a few different types of different little fishies, but then I thought that maybe I could get a betta and give him a few tankmates. I was thinking a small group of kuhli loaches for the bottom (which should be fine) but I was thinking of getting maybe 4-5 harlequin tetras?? the tank has a fair amount of hiding spots (I have two fake log ornament thingies that have hiding holes in them, and I am going to get a few fake plants as hiding spots too)
Basically my question is, are harlequin tetras good tankmates for bettas? if not then what kind of small fish would be more suitable as tankmates?
