The Black Ghost Knifefish requires a tank with really good filtration, they tend to be timid and will hide and as such prefer aquariums with plenty of hiding spaces (e.g. roots, rocks, driftwood) and fine-gravel substrate. They do well with other large peaceful fish but may be aggressive towards smaller or similar-sized species.
