What topwater fish to get?

Tank size 120: dimensions 58.5 inches long, 16.5 inches wide, and 28 inches tall

tank mates would be: 1 angelfish, 1 black ghost knife, 1 rhino pleco, 2 spotted rapheals.

I need help figuring out a good mid to top water fish that has a max length less than 12 inches.

It would also need to be peaceful enough to happily live with the above tank mates.

Ph 7.6, Temp 76f - 82f
Semi hard water

No live plants will be used. except algae.
Also gars are illegal. And an arowana would be to big.

Thak you for your help

Thanks deeb, but i doubt i can get that through the lfs, but ill double check tomorrow.

what else?

Out of the ones suggest the ones i know my lfs can gat are african butterfly fish, hatchets, and needle gar.

leaning towards these two: african butterflyfish or school of hatchets.

wich would be the best?

hatchets would have plastic plants to hide in but i am worried they would become a snack for the black ghost knife.

Would the butterfly fish become to aggresive?
