How fast will sevs eat plants? I want some floating plants for the Limas but i know sevs love to munch on them so i was thinking if once i get the tank set up throw in a load of duckweed and let it cover the tank before i get the sevs and hopefully it would mange to reproduce as fast as the sevs are eating it so there would always be floating plants. Could that work?
Sevs will eat plants as quickly as they discover they are edible. Basically straight away

I had to move my live plants out of my 50g with my Rotties in as they kept munching on them. My Betta appreciates them much more
