a 4*2*2 is the same tank i have. Its plenty of tank, but as mentioned earlier you should adjust the stocking a bit. IMO that tank is not the best pred tank because of length.
all your suggestions are great. the 120 is the longest and widest i can go due to spouse restraints. all i know is an eel will be the basis for my stocking, and i would love the tusk but well see. i'd rather keep things light than crowded, and i know the eel alone is pushing the envelope.
