Need some help re-arranging fish.

[Gonzaga]

I just picked up a TSN at my LFS and I need to put some fish in some different tanks.

I have as the follows and need to put my TSN in one of these tanks.

20 Gal. 6"Arowana, 6"Jag
10 Gal. Hex Empty
40 Gal. 6"GT, 4"JD, Syno Cat
75 Gal. 9"Pbass, 7"RTC, 2 Tinfoil Barbs, Con Pair.

The TSN is just shy of 4". Where should I put him? What could I switch around?

seriously need to get larger tanks. the 75 isn't even close to big enough to house most of these monsters for long. plus i don't know how it hasn't already happened but don't make big plans for u'r barbs or convicts as long as that rt is around. but if i had to say a tank i'd prolly say the 40 even though the jacks will kick the crap outta them but in the bigger tank it wouldn't stand a chance with the rt.

I've done plenty of research and have a 155 that is cycling and I've got two 600 gallon ponds waiting on the side of my house. All these tanks are just for growth purposes. I'm actually waiting for my RTC to eat the cons!
