Sorry to make another topic like this but i need some advice on my 180 litres stocking. I currently have 3 Pearl Gourami's, 4 Zebra danios, 7 Harlequin rasbora, 6 bronze corys and a kuhli loach. At the moment i plan on getting more zebras and kuhli's. I am also considering a small catfish of some kind (thinking maybe a whiptail) and i am also beginning to look at killifish. Any opinions on this?, should i leave it as is or what?
