Okay, i i just bought some of this amazing fishes...im keeping them with my clown laoches, as well as tiger and rosy barbs..so far doing quite fine...but i heard they prefer live foods...i cant seem to find any live food that is smalle enuff to fee dhim though...coz my knifes fishes are kinda small size...abit longer than my tiger barbs...same size as my rosy and clown loaches....the tiger barbs did try to nip them, but after a while they dun bother since i have 10 of the tiger barbs, so after some time they just ignore them as well...just wondering how big can they get when full grown?

This shrimp is so good it needs to be seen in wide
I have a ghost knife too. Amazing fish aren't they? But it says in your sig you have 5 ghost knives! The rule is only one per tank, because the weak electrical organ they use to find food can be interrupted by other ghost knives electric signals. As for your questions they get pretty big! And fast too! They get up to 24inches fully in the wild with good water conditions, but usually 12-18 inches in an aquarium. You said your ghost knifes are small - with live food expect them to be 8 inches each within a year. They don't need the live food although they like it better, I just use frozen ones. Any more questions or comments just post

It wont affect growth, just that the electrical signal gets interrupted. Just feed them bloodworms frozen or live.
I didn't exactly get that question, did you mean do they eat other fish? Not really, if they are small enough to fit in the mouth I would say yes.

OMG! 5....
This is not a good plan, how big is the tank?? I would agree one per tank is best, and as pointed out, these fish get HUGE.
Here is a caution from a BGK owners web page:

I hope the cowboy who sold them to you will take four of them back!

Eh there's no way i can retunr my fishes...hah...so i guess i just see how the 5 ghost fishes works in my tank...hah...but they dun stay toegther most of the time anyway...i have quite anumber of plants and they tend to hide in their respective locations, occasionally swim here and there, and hide again...the tiger barbs dun seem to bother about them also

Soon enough the black ghost knifes will get so big, that they should only live with other big invertibrates (i.e -plecostumus's, black sharks, etc) 
Edit: but im not exactly sure on the growth speed. Let just say until there mouths are big enough to engulf the other fish. Just think obviously. BGK's have big mouths too!
Take them out when you think they are too big.

They will eat bigger shrimp than just brine shrimp, anything under 3" will make a tastey snack for a 8" BGK 
Not that you need worry, with 5 in the tank (unless its 300 gallons plus) the fish wont survive long anyway, as already mentioned they use a electrical organ to find food and navigate around objects in the tank, if this is disturbed the fish become stressed and will probably die. Also live foods are a must until you can train tour bgk to take non live foods, they require their food to be moving to be able to locate it and since these fish have most likely been taken from the wild they will not have seen many pellet and flake foods

Uhh, well what I do is I put the food right in front of them so they find it immediatly. Works a charm . And If I put live food other fish get it before my bgk does, so yeah.
