So yes I got a new fish on impulse. Well it's not a full outright impulse buy since I've looked into getting killis before.

Here's the story:
I had been checking the feed store( they have lot of animals, like a petshop) to get new driftwood for my clown plecos. So I look at their fish selection, which is good, though I am not actively in the market for new fishies.
I find two baby silver aros and overall their fish look well taken care and besides the aros I happily note the overall lack of tankbuster fish such as pacos, irredescent sharks etc.

I look into a guppy tank and find a fish that I've never seen before, a male killifish of some kind ( panchax species I'm guessing). I've never seen a fish like this, then again I hardly ever see any killis.

I curiously ask about said fish and get the fish offered to me for the price of a common guppy. This fish seems to have a history of being returned to the store twice for being aggressive, the fish's origins being that the original person who had the fish gave him to the store. Nobody at the store had ever seen a fish like this before either.

Do I have a community tank?. because if so, then it's not the fish for me.
Now my tank I could put the killi in is my planted twenty gal which houses a single female betta. I'm not terribly concerned about an aggressive loner fish, because I've no desire for a community tank and like my simplistic planted tank.
I take note of a male betta already in with the guppies and killifish hoping this means it'll work out ok. They have assured me if it doesn't work out I can return the killi. Yeah so I get tempted enough to buy the killi. I figured it's a chance to get a rare killifish for the price of a common guppy, probably not going to come up again.

So my new killi is mostly yellow. Due to the coloration, I'm assuming it's a male killi. Looks like a predatory fish with a large, upward turning, pointed mouth. Has a long streamlinned shaped body.
Is said to be aggressive, though I don't know under what circumstances, Anyone have a clue what this killifish could be?.

EDIT: I think I've found the killi's ID already. I think he is a golden panchax, that was quick eh?.

the panchax are not aggressive so much as a bully. They can get pretty big and thick and have been known to eat small fish like neons so are not for the peaceful community but I had a pair in with my rtb shark, bumblebee cat etc and no probs. I love their expressions
 
Had 2 just lost 1.........beautifull, active, top dwelling fish.......

mine is feeding on small FD shrimp...........bloodworms, blackworms, flake.........pretty much anything, even pellets every now and again!!!

btw mine is approx 3"....
 
This is a FAVORITE of mine as far as smaller fish. They are not too territorial but be CAREFUL they are very very predatory (I call them micropikes!). My first one was in a planted tank with white clouds and harlequin rasboras. One by one the smaller fish were disappearing...and I couldn't figure out why until one day when I watched the killi flex his jaws. I was like...oh wow those open pretty big. As they grow larger and more dominant they can get VERY brightly colored. Mine glowed in the freakin dark when he got to about 3 inches.

Anyhow...Enjoy!
 
Golden panchax adult size: 4 inches.
Betta adult size: 3 size.
So I'm going to assume that a predatory fish will kill a fish half their size or under.
 
I've got 2 of what petsmart sells as golden wonder killies in a planted tank with a few black skirt tetras and some corys, no aggression. They really like freeze dried blackworms, and they've also eaten very small ghost/grass shrimp
 
Going to photograph the killi later to make sure, but he's hiding and I'd rather not stress out a new fish too much, so it'll wait.
