Just a quick on.

Just wondering what size tank i would be able to house a niger catfish , peruno catfish, motoro stingray, severam cichlids,2 pacu , clownknife (mabey) ,silver arowana and mabey some other cichlid that gets a fair size (12"-14") ?

I was thinking 8(L) x 4(H) x 4 (w).

Would this suit them ?

thanks
Dav.
