I had no plans of adding any moref fish. Well some more lemons.I would not add any fish to that stock unless you are going to be getting rid of what you have. Severum and six cupid's is already at max capacity cichlid-wise in my opinion.
If you want to do the cryptoheros, like the sajica, you will need to start fresh. They are much more aggressive than your current stock.
If you were to find other homes for all of your other fish, I'd say you could do 5 sajicas pretty easily in a 75, with lots of décor. One male and four females would be your best bet. You could try two males, one might kill the other though. It's kind of hit-or-miss keeping multiple pairs in a four foot tank.
But I Love how the sajica looks.
I will not get 5 or 6 of the same fish unless their schooling.
Omg. I'm so confuse. Not sure what to do
