4 Meter Aquarium, Snow white platinum gar, Hypostomus luteus, BB & HB Arowana Couple, Tigerrochen... 

Mega, wie immer lieber Addi! Viele Grüße Faton 😊

Not to be a PIA...but aren't those Gars getting to big? or will? You have those great Arowana. The Gars are looking great and they are fish that aren't all that active..but still,that tank is not wider than they are long. Or,won't be soon. At least you give great care,I give you that.

That pleco🥺🧡

What kind of filter are u using?

Very classy aquarium
