    Nocturnal fish, thus shy in day time. they do jump! And will eat small fish. No scales so parasites can be a problem.

    Very slow growth rate. Mine hides entirely during the day and only comes out when all the lights are switched off."oscar freak is you dont mind I will be tagging along with this.
    I actually wanna build him a tank. What dimensions will be adequate for a adult?

    BGF are very interesting fish,
    They just look amazing

    Mine grew very fast from 3-12cm, unfortunately he just does not want to grow anymore.
    I have mine with parrot cichlids, deacons, uaru , clown loaches

    He stays alot between the driftwood and rocks

    In the wild they grow big, like in almost half a meter(45cm). In aquariums they usually only get half that. 25cm.

    Feeding; because they are nocturnal you must feed few minutes after light out so that the food can sink down with out being eaten by the tankmates. Its a carnivor and would eat beefheart, shrimp, snails, bloodworm, tubiflex ect.

    Also, when treating with meds, be careful of ones that have copper in them.

    If you're talking 900mm, then no. As a grow-out tank it'll work but not for the long term. As mentioned earlier, they have the potential to grow to 50cm, although I've never seen an aquarium kept specimen over 30cm. Try for 1500mmx600mmx600mm for a long-term arrangement.

    If you're not keen on the BGK, try a very close relative, the Brown Ghost Knifefish (Apteronotus leptorhynchus). They get to about half the size I think. I kept one before and I have to say that they're every bit as interesting as BGKs. Not as common but I'm sure if you sweet talk your LFS they'll be able to find some for you.

    I have one in a 900cm tank, hey like to stay in the cave alot and does come out in morning and late afternoon, they are very shy eaters though and can sometime be bullied away from food when very small. I feed him bloodworm , real worms reaaly enjoys that and he also enjoy eating the tetra sinking food the small red stuff. He is learning from my eel and know whats to eat out of my hand. the grow fastish when the small but then the slow down abit. seen some really big one like 30cm, mine is over 12cm and have had him for about 7months where when i got him he was 5cm. Must be honest the fish have huge mouth and im sure the help the eel when it comes to eating the guppy babies( i have guppies to breed and feed my eel)

    must say if u enjoy watching you fish swim then bgk are the best cause they have the most eligant way of swimming and feeding.

    If anyone is interested in the fish they must get hold of me, cause im off to NZ and unfortunetly have to get sell my fish and tank
