American Flagfish compatibility?

[koaladarshana]

I saw some american flagfish at my LFS today and I'm in love! I was told by an employee that they'd be compatible with my current stock...

pygmy cories
endlers
galaxy rasboras
cardinal tetras (I would re-home these for flagfish, however)

... but I was skeptical! Knowing all too well that I should do my research and avoid impulse buys... I came across some info saying they are peaceful, other saying they are too aggressive for community tanks...

Basically, what do I need to know about these beautiful killies? Thanks guys!

Flagfish just are one of those fish that are really unpredictable. Some have no problems with their flagfish, others report predatory, nippy, aggressive tendencies. However,given the significant size discrepancy between a fully grown flagfish and the rest of your stock, as well as the aggression that seems to occur with every second individual who buys a flagfish, I really would not risk putting a flagfish with the rest of your fish.

Good to know... I'll pass on the flagfish for now... I'm way more fond of my cories, endlers and rasboras.

Muchas gracias!

One of our most colorful native fish.

Am I right in saying they also prefer slightly cooler temps?

[madagascariensis]

Yes. They are temperate fish actually so they won't mind temperatures down to 18 edges Celsius, and possibly even lower. Conversely though they come from shallow swamps that heat up fast and don't mind really high temperatures either, although high temps may increase aggression.
