They might have better hearing then some other plecos
The authors also indicated that in taxa among the Hypoptopomatinae, the
large and well-perforated compound pterotic probably increases sound transmission to the inner ear. Based on this
information it is assumed that in Acanthicus, Megalancistrus and Panaque the perception of sound might be more
efficient than in other Loricariidae with the same proportion of swim bladder capsule and body size.

They are found in areas of both high and low current.
Apparently they are a rather recently evolved species http://agrilife.org/aquaticecology/files/2014/11/Lujan-2014.pdf

He does indeed eat mostly at night when the lights are completely out. Eating sinking pellets and also he's chewing on the driftwood, making relatively thin poops for his size.
He also - I swear I haven't had him long enough for it - but he's grown.

Another keeper of murder pleco:
My own Acanthicus hystrix shows the most premeditated aggression I have ever seen in a fish. Not being a good swimmer, he has little chance of catching anything in midwater, so lurks patiently until he spots a fish swimming between him and the glass. At this point he erects his long and unpleasant interopercular spines and with a well-timed rush impales his unfortunate victim against the glass. After he has sawed backwards and forwards a few times, he retreats to allow the luckless recipient to float to the top. He succeeded in performing this manoeuvre three times before his ‘benefit of the doubt’ was withdrawn, and now lives in solitary splendour.

This here indicates that Hystrix is the big one, and Adonis isn't. But they've been wrong before.
