Hello, I'll start by saying I'm new to the aquatic world meaning I started my first aquarium last month, I have 10 a.c, a Texas cichlid and a pleco. All the cichlids are still pretty small I bought all of them at around the same size 3" - 4" and I was wondering if it's ok to add a clown or a royal knifefish in there mainly because I don't want to keep it strictly cichlids. I got a 45 gal
tank. And right now with all the fish already there for a little more than three weeks it looks kinda empty.
