Aggressive 

Price: 85.98 

Qty/box: 10pcs

Gender: NA

Water condition: Freshwater, PH 6.0 - 7.5

Tank mates: Must keep an adult Gymnarchus niloticus (Aba Aba) alone, as they are highly aggressive and predatory, with a powerful bite that can injure or kill other fish, even large tank mates. If you must try to house them with others, only very large, armored fish like some species of Megalodoras or adult Polypterus are potential, though risky, companions, and you should always have a backup tank ready. Avoid any other knifefish or electric fish.
