I'm trying to make a plan for my 75. It will be planted with lots of dirftwood as decor. It will be a low light, low tech setup. I'm trying to decide what fish i want. I'm not into neon tetras, or guppies or anything like that. Currently im trying to decide between 12-15 exodon tetras or 5 or so angel fish. What do you guys think? Are there going to be negatives to keeping predators like exo's in my planted tank? What fish would all of you recommend? experiences good or bad?
