Most impressive home aquarium fish...

[Soil]

I'd say a big, mean walking frogfish/anglerfish

 

[cichlidinsomniac]

[Bottomfeeder]

For me:
Scomb, Datnoid, Jaguar Guatope, Silver Arow, and call me crazy but I love the slow swagger of a BIG Piranha.

 

[guerilla 33]

vampire tetra or goliath tiger fish are damn impressive

 

[RogierT]

Salt water: Scorpionfish. Must have seen them 1000 times, but still makes me think: GDAMN I WANT ONE.
Fresh water: Arowana's, no1 for me.

You said earlier this is SW right? I can't
FW- Planted discus tank, and not that 75g crap. No need to go crazy here, 200-300 gallons would make room for a good 10-15 school of discus with some clown loaches in bottom and maybe a small school of dithers.

i just threw up a lil

i would love 2 Astronotus crassipinnis, a Goliath dat, 3 florida gar, and as many birchirs as i could cram in e.g. P. delhazi, P. endlicheri, P.palmas polli, and P. ornatipinnis

nioce!
