Hello everyone! I have a ten gallon tank with only 1 Flame tetra. Yes, the other 4 have died because while I was away a disaster struck. The one flame tetra is really happy with all the room. In fact, his colors are better then when he was with the other flame tetras! I figure that I do not want to add other flame tetras because I really like the one I have. I know it sounds weird but I feel like he is a survivor and I want him to stand out. I am thinking about neon tetras. I am just stuck at how many I can add maximum and how fast I should add them. Any help would be appreciated!
