I currently own a 65g planted tank. I have a pressurized co2 setup and 198watts of light going to it. I currently have the tank stocked with, 5 raspboras, 5 pristilla tetras, 10 neon tetras, 4 cory, 2 sae's, 5 ottos, 2 bristlenose plecos, 1 marbled angelfish. I used to have two angelfish and they had paired off and started laying eggs. One died when I moved 2hrs down the road. The plants have grown out quite a bit and there is cover amongst the plants. My question is that will I be able to add another angelfish without an aggression problem? My angelfish has shown some aggression towards the other fish. If I can't add anymore angels I'm wondering what other type of fish I could add?
