Every web site I read to research a fish before I buy, says something different! Figured I would ask here for some first hand experience help. I am stocking my 100g tank. Currently I have 8 black neons, 8 red n blue columbians, 5 red eye and 3 serpa tetras. As of tomorrow the red eye school will go up to 8 and the serpa will be at 8 as well. I'm wanting a few larger either individual or pairs to add to this community tank. Some sites say a blood parrot is OK, some say no way. Most say angels will be OK...so my question is, can i safely add a pair of angels and a pair of blood parrots or no? If not, what other larger, colorful, full of personality fish can I add?
