I've seen Hoplias in action in Uruguay. Your 265g will be just about right for one.

This one will feed on anything, he's only about 6" now and mean as can be, he was in a 55 with a Rd growout and the rd pushed him too far one night and he took two chunks out of it killing it...good thing is this is just a malabaricus and should only get about 16" tops

Fishbase lists them to 55 cm which is about 22".

They have a really wide range and array of colorations. The one that we (meaning Felipe and Pedro) seined up in the Rio Yi was MONSTROUS - every bit of 2' and probably 6" wide!

I know aimara get very big but I've never seen a malabaricus over 16" in aquaria

That's a beast of a fish. He'd be a joy to watch in your upcoming 265 (if I read that correctly). That's a monster tank!

My question, how do you get your substrate to stand vertically like that? Whenever I try that gravity makes all the sand collapse. You must share your secret! Anti-gravity would be the key to explaining why we have observations of the universe expanding at an increasing rate! :p

Is there anything that can be kept with those guys? I've heard that even the same-sized fish will get chunks taken out by wolves.

I've seen them in community tanks with other monster fish, for the most part the wolf is pretty docile, the only time my wolf showed aggression was when my red devil went after him, the wolf took chunks out of him

Also that video is of hoplias aimara, they get much bigger and cost a lot more than malabaricus (common wolf)

I wouldn't keep a big wolf with anything that I would care went missing or was torn to pieces. Kind of like an African Lungfish...

We collected a bunch of them in Uruguay and unless housed individually the larger ones would eat the smaller ones (and anything else). Like a 3" wolf fish will eat a 2.5" wolf fish. Or a 1" one will eat another 1" one!

What's interesting is that we collected both Hoplias malabaricus and lacerdae in Constituction (off of the Rio Uruguay) in Western Uruguay. Lacerdae gets to about 3' long (!) while malabaricus gets to ~2'. If you look at the gills from the bottom of the fish, the gill plates come together for malabaricus and are straight for lacerdae (or maybe it's the other way around). Otherwise, they're pretty much indestinguishable otherwise (and I'm sure interbreed).

The hobby has decided that H. lacerdae is the holy grail and worth hundreds (thousands!) of dollars. Folks spent a lot of time looking at the bottoms of wolf fish to try to pick out H. lacerdae to bring back. And in the end most of them ate each other along the way ;)

I brought back a baby last trip and (my own fault) it jumped out...
