Thanks for the advice guys. I guess angels in a 29 gallon tank isn't quite as clear-cut as I thought it would be based on the number of opinions here.
The tank will at some point be heavily planted as soon as the plants grow. If I did do 3-4 angelfish, it'd just be the angelfish and maybe some ottos, nothing else. Not too sure how this would be practically or aesthetically.
Would it be better to maybe get a breeding pair (or just a compatible pair) of angels as well as some schooling fish that would get along? If it gets anymore confusing I must just have to convert it into another shrimp farm :silly:
