I have raised a Saggitae from fry to adult and wouldn't want to house it in a 75 myself. 
What I started with

My boy Casper now 2 years old
Amphilophus are a great sp. very outgoing, very personable. I would suggest Lyonsi if you want to go the Amp route. Males are said to only grow out to the 10in mark, females 8in.
Not my pic, thank Google, here a pair of Lyonsi
