Alright so now that I have solved my angelfish nipping problem I need to kind of restock my 45 gallon. I have 5 angels in it, 2 bala sharks, and 3 pictus cats. Now the bala sharks, and the 3 pictus cats will eventually end up in my 180 when they get big enough to not get eaten by my oscar. So I would like to stock the 45 with kind of a South American natural angelfish habitat type of thing. So I would like to add either 2 bolivian or german blue rams. Any other suggestions? I would love to add like 10 cardinal tetras and since the angels are so tiny would it worK? I am open to suggestions. Thanks
