Hi I have a 60 gallon tank with just 6 columbian tetras and a SRBN pleco. I am going to add soon a red shoulder severum, green phantom pleco, striped Raphael catfish to the tank. Now i know the severum will limit my stock being quite big but is there anything I could add. Something like some more dithers or a oddball or a cichlid. Because at the moment it's looking quite bare with just 6 columbian tetras and even when I add the severum it will look bare a the top or middle because plecos and catfish hide so even something like a ram or kribensis or jewel would be ok. I just need to know if there's some room. All replys are welcome. Thanks in advance
