will my tank be overstocked?

[batang_mcdo]

I have a 300 gallon tank with 6 adult severums and 4 pcs 5 inch true parrot cichlids. I;m planning to move my 18 inch super red to this tank.
maybe together with 2 8 inch motoros. will my tank be overstocked?

Water change will be once every 2 week, maybe 30 - 40 %
filtration is 75 gallon sump, 55 gallon drum filter filled with scrubbies.
and 4 ft 2 layer overhead filter with 3 large sponge filters inside.

Can this work?

or do i have to get rid of some severums?

im no expert. i think it will work tho. definitely seems like you have alot of filtration going. ive definitely seen more heavily stocked 300's out there.

Doesn't sound overstocked, but what width is the tank, as the Motoros will eventually need a width of at least 36''.
