Either way will work. I got my plants after I got my fish. Next time I set up an aquarium, I think I'll get at least some plants before I get the fish. It's easier to set up the plants without the fish in there, 'cause you don't have to worry about stressing out the fish too much if you don'ot like the way your plants are arranged. Like I said though, it'll work either way.brookie said:im getting starter fish for my 10 gal i was wondering if it would be better to get plants first or the fish?
