?Best size tank for these fish?

[wannaarro]

Trying to figure out best size tank for:
(all still juveniles, 1 of each)
* Green Sev
* Jack Dempsey female
* Paratilapia polleni (max length 14", height @8")
* BGK
* in new home, thinking of some pictus cats

Been enlarging their space; presently in a 55g with largest being Sev and BGK at 7" long. Will I need more than 2ft wide? Shooting for something like a
125w=6ft long, 2 ft wide, 17" tall.

Any recommendations? Want my little monsters to be happy. . .
(BTW, I live in a 1999 mobilehome so I can't go huge on the tank . . teachers don't get paid ****e)
Thanks!

Im immagining along the way that your going to buy more fish. I do like the WIDE idea tho. Maybe a 150 wide? Maybe,(not sure), it could be 30" wide. But I doubt it. Even if its not, and is standard, go 150 because thts a 2ft wide anyway.

Nope, don't plan on adding more fish, I have other tanks. And I don't want a random mix any more that I have--the polleni is Malagascy. If I get (lol) more fish, they'll need a bigger tank!!
