My Stock So Far

[carpus]

hello all

so far in my 55g tank i have the fish listed below

3 golden rams(2 have paired up)
2 apiso cacatuoides paired up
1 bn pleco
2 corys
10 cardinal tetras
10 amano shrimp

ive got a pair of apisto viejita II coming at the weekend

the tank has been running for 3 months now with no deaths so far.

how many more pairs would be ok to put in the tank?

im thinking of rehoming the pleco and the other male ram
as the plec eat the eggs of the other 2 rams and the odd male ram hassles the pair all the time

thanks
