Hello, I don't have an aquarium yet but I've been planning out every part of it before I actually start so I don't screw up. I eventually want to get one Rainbow shark, but first I was going to start the Nitrogen cycle and put in a group of Tiger barb. I read up about tiger barb, and they're pretty tolerant, was thinking of getting about 7 so that they can have a nice school and then when they're healthy and established, introduce a Rainbow Shark.
...My question is I was thinking of getting about a 29 gallon tank, and it says that these tiger barbs like a lot of vegetation. Some sources recommend filling 2/3rds of the tank with heavy vegetation and leaving room for swimming, I was wondering if I could get away with using fake plants or if I would need live plants. Does it make a difference?
