Satanoperca and geophagus..can i????

[dccruibay5]

Hi,
I'm planning to put in my 150x45x55a little group of geophagus,but in these days i've read a lot of article of satanoperca leucosticta.. but... i've read in the web,that someone say that they will grow up to 30cm,other say 25 cm..another no more 15 cm... i'm a little bit confused..and,can i put some pterophyllu whit those or some mesonauta ?
PS:if you have another suggestions for this tank,please tell me..

I've also found some geophagus parnaibae...what d you think about they???
Thanks in advice

25-30cm is very realistic for a S.leucosticta. Your tank isnt large enough for any group of eartheaters growing over 8" and even that is a stretch.
