Killi is from the Dutch word for Ditch where they are found. Killifish don’t need large tanks. 20 or 30 Gal is fine for them. Some types do best in same species tanks because some can be hard to keep due to them being very sensitive to water chemistry. They are similar to bettas. Males should not be kept together. but you can and should keep 2 females and one male. Or 2 pairs of 3.

So it depends on what type of killi you are looking to get.

Here are some good sites to check out.
