I kind of wanted to add a Betta to my tank that has shrimp and neons. Someone at my fish store told me they might be inclined to try and eat the neons, whereas someone else from a different fish store said the opposite would be more likely to happen, ie. the Neons nipping at his fins. I've had a Betta in with my Glowlights before and they all left each other alone. I'm just wondering if this is a good idea, though I am trying to stick to the South American theme.
