Red Terror Pair In 450l Tank

[spikeyboy]

I saw a stunning breeding pair of Red Terrors in My LFS.They are around 8-10 inches.

Can i keep them in a Jewel Vision 450.Filtered by a Fluval FX5 ?

What`s the chances of them killing each other ?

Can i add anymore fish in the tank ? If yes any ideas ?
