Some deep-bodied tetras such as diamond tetras will look stunning in her tank.:hearts: Hope she provides plants as well to make her tank look quite natural.
no danios, neons, cardinals, barbs, african cichlids, clown loaches (well, they get to bgi anyway) sharks, or white clouds. stay away from rainbowfish. they can be kept together, but the rainbows are just to hyperactive.
Agree w/ most of the above choices but before adding it would be good to know how many angels are presently in the 35g? How big are they? What type of filtration? Is it fully established? Not trying to be a wet blanket but these are important ques. for success. Good luck, "T"
I have glo-lite tetras, red-eye tetras, and neon tetras (which I wouldn't recommend as I heard that angel fish can dine on these guys).
I have also had cories and platys in with mine with no problems. My angel is way laid back and stays to himself all of the time. He is almost 5 inches now.
