Hi I want to house an angelfish in a 30 gallon with some panda cories and maybe a dwarf gourami. I would also like a school of tetras in the tank. Problem is I heard angelfish eat small tetras. I know I won't get neon tetras for sure, but I'm thinking of getting a school of cardinal or penguin tetras. But will these fish also get eaten by the angelfish? And if so, which species of tetra similar to these varieties will the angelfish not eat? All advice and comments greatly appreciated!
