Australe Killifish Tank Setup
Plan for at least 10.6 US gal min of water—that is the minimum in our database for a workable setup, not a challenge to crowd fish. Aim to hold 64–75°F and pH 6–7.5 without daily drama. These fish use the Top/Mid zone most, so put wood, plants, or open water there accordingly.
What Do Australe Killifishs Eat?
We record diet as Carnivore (micro/live foods). Offer a few food types that match—dry, frozen, or gel—and swap now and then. One flake every day for a year is how dull color and gut trouble creep in.
Australe Killifish Tank Mates
Temperament in the data: Peaceful. Beautiful West African killifish. Cooler water than most tropicals. Live food preferred; will take frozen. Plug your full stock list into the stocking calculator—single-species compatibility scores are hints, not a whole-tank verdict.
Are Australe Killifishs Good for Beginners?
We rate this as intermediate. Budget time for testing, maintenance, and watching behaviour if the water looks fine but the fish do not. If this would be your very first tank, start with something more forgiving and come back to this one.
