All that being said I would not recommend them in a large tank. They can be quite shy and easily outcompeted for food. Your also not going to be able to appreciate their beauty due to their size and the size of your tank. My other killi's which are all smaller species are kept in smaller tanks not larger than 24 gallons and the ones in community tanks are housed with nano fish.
