Hello All,

Ive Googled this but had no luck. Just wondering if anyone can name some predatory fish that are active swimmers similar to how an arowana swims around, not looking for anything that grows over 12inches. I have 2 55g tanks with a red wolf in one and a Channa Pulchra in the other. They are rather boring and don’t move unless it’s time to eat?.

Ugh tough order here lol, not many active predator fish that stay small that I know of. You could possibly get some nimbochromis venustus, nimbochromis livingstonii, nimbochromis linni, nimbochromis polystigma, nimbochromis fuscotaeniatus. Honestly can't think of much of anything else except the nimbochromis species, could possibly do some catfish but in my mind most are scavengers rather then predators. Hope this helps ya in some way and I'm certain someone else will come along and give some more suggestions.

The ones I saw were kept in a large shoal, reminded me of swordtails with attitude.
Chalceus is another one.

Ever see a belonesox eat? It's so weird and amazing at the same time. Just imagine your bottom jaw being stuck permanently in place while the top jaw is what moves and pivots/shovels food in. Chalceus would be a good one too, basically another top water predator with a torpedo for a body.

Large chalceus are impressive fish, had a 8 inch one a while ago. Belonesox I find fascinating, been tempted a few times but I work away so the wife feeds my tanks, i need fish that easily accept pellets, something that from the research i did belonesox don't.

Yeah I heard the same. My ex-roommate had a male belonesox and he eventually got it to eat flake food. It was hilarious to whatch it eat, it would rocket forward skimming the surface and basically shovel everything straight down it's throat. Atleast they are easy to sex tho, exactly the same as a guppy. Neat that they are live bearers too. Got to have a tight fitting lid for chalceus tho, found mine behind the tank the day after it went missing, it got out thru a 2 inch opening next to the filter.
 
I would consider 55 gal tanks too small for any active, 8" predators.
There just isn't enough space for them to act normally, so in small tanks most sizeable predators sit around and mope
You might find a shoal of tetras, or the above mentioned Belonesox, that stay small to be a much more interesting and an active display, and although most people don't think of small tetras as predators, they are.....and just as lethal as their larger cousins, piranhas.
