Geophagus Species in a tank

[AquaJason]

Hi, really into geoghagus species and would potentially like to get a group, what are your suggestions for first time geophagus species- I like the tapajos(orange heads) and altifrons. What would be a suitable number and minimum tank size. I am getting approximatly a 100G tank, although currently have a full grown festivum(5inch), a female green sev(5inch) and a blood parrot(4inch) which would also be in the tank- would I still be able to house geophagus or would that be pushing it?
Thanks
Jason

What's the footprint of the 100g tank?

Not sure on stocking because it would depend on your setup & filtration but those 2 you mentioned are good choices....

For a 100g tank and your current tankmates I'd stick with a school of G. sp. "Orange Head Tapajos" (aka Red Heads) and skip the G. altifrons
