how tall does a clown knife get?

#1
i know a clown knife can get up to 3 feet long, but how tall do they get? i am building a tank 2x3x7 and was wondering if that would be tall enough. also, should i put real plants in it or fake ones? i have never done real ones before, would the extra trouble be worth it?

Figure you need enough room for him to turn around as an adult... if he's 3' long, he won't be able to comfortably turn around in a 3' wide tank. Plus, he can't swim very far lengthwise, either. That's like keeping a neon tetra in something 3"longx2"tallx1.5"wide.... not a whole lot of room.

Can you make it like 4'widex10-12'longx3'tall or larger?

That's probably good enough... I don't think the height tends to matter as much as length and width. Four feet wide is enough to turn around in at least.

How are you going to make a massive shelter for him?
