need some help stocking my 125g

[cyclops23]

my LFS just got in 2 red tail barracudas, i'm hooked! man those things are awesome! i got to feed them, very imperssive show. they were lightning fast. i figure i'm gonna get about 6 of them for my 125, but what else can i put in there with them?

i really want to get a black ghost knife, a pictus cat, and either a tire track eel or a fire eel. doable?

you could try the knife and some kind of cat but tire track or fire eel can get 3' so it might be able to eat you barracuda but id get a poly of some kind but if the baracuda were big you could try the fire eel there less preditory then tiretrack eels

how fast do the tire track or fire eel grow? do they get big fast?
