Hey I'm wanting to get into cichlids and I have a 20L tank. I have a 60 gallon Whisper power filter for it. I'll probably use sand as substrate. And probably just fake plants. I'm going to need smaller cichlids as I was hoping to do something like 2 cichlids, a school of 5 or 6 tetra, and 4 or 5 cories. What do you guys recommend?
