Silver Arowana and African Knife Fish Compatibility?
Hey guys.. I just introduced a African Knife Fish into my Silver Aro tank. Are they compatible? I thought I saw the Knife fish take a bite at my Arowana. Any suggestions or has any one been in a situation like this before. My tank is around 180 gallons. Aro is around a foot and knife must be about 20 cm. The tank is bare.. no gravel no deco..nothing.. I thought of putting a pipe in so the knife could hide in the morning when the lights are on and i could switch it off in the night so he can swim around.. Please help. thanks.
 
Really depends on the fish itself. I have a Silver and Clown and they get along great.

That's a nice tank, I like the big rocks mixed in with the gravel like that, looks cool.

I think in the end the arowana will grow big enough to eat your African knife. ABKs don't get really big, 12" seems to be exceptional with 8" being a common max tank size. An adult silver could eat one pretty easy...probably better off with a clown knife if you have the space, or a black ghost knife if you can find a big one.
 
@masterb - thanks mate.. seems to have settled down.. put in a pipe and he seems to be resting it out there.. and ya awesome tank :)

@ctu2fan - i think my african knife has maxed it already.. he is around 8" and my aro is growing.. close to 12" to 13" now.. I actually have an offer for a BGK now.. but then i dont wanna give away the african knife too.. do you think its wise i put in a BGK and a african knife together with the aro? I read about BGK and they are intolerant to same and related species but then again like masterb says depends on the fish itself.. do let me know guys cheers..
 
Yeah, it depends on the individual fish.

I had a clown knife fish that would leave the silver arowanas alone, and yet would constantly fight with the jardini.

It doesn't really matter how many fish you put in there with your arowana. If any of the fish are too small, they'll be eaten.

I'm not sure whether or not your ABK and BGK will mix together either. BGKs need to be monitored when mixed with other electric species.
 
@jux - thanks mate

@mei - true very true.. hmmm.. i didnt think i'd find a knife fish first in India and in my lil city and by chance i find a african knife fish and again in a couple of days i find a BGK that i always wanted.. the lord does work in mysterious ways and when it rains it pours.. now is the time i be more sensible i guess.. cheers mate..
 
It will probably be fine for now, but just remember that the Aro will grow so much larger than an ABK and grow faster than a BGK. They may become a meal in the future.
 
@benzjamin - ;) true my aro keeps scoping my BGK all the time.. but doesnt really go for him.. well lets see.. just waiting to construct my monster tank (12X6X5 ft) in concrete and then i'll move the arowanas in there..
