[Filtration recommendation]

Hey @subramn
If you have an STT of 6+ months this tank with so few guppies could even run without a filter at all provided you have at least a bit of gravel/sand on the bottom.So your current setup should be more than good enough.

[Guppy or endler]

Hello,

As far as i am aware there is not any "pure" endlers being sold to the hobby anymore.
Almost all fish labeled as endler are a endler/guppy mix and most of the guppies usually have some endler mixed in because it makes them more robust and more colorful.
That being said the fish on the picture is a mix and usually would be labeled as an enlder in most stores.
