My plan is to get Angelfish and neon tetras when they are young so they grow together and don't view each other as food. Now I know I run the risk of Angels eating neon tetras as they are 1.5 inches adult size. But, do you think a large enough school of neon tetras will keep them safe? My main concern is the water temperatures My tank is 78F and I hear that temp will threaten their life span by a lot. Also my tank size is 75 gallons and I will be under stocking at 40 gallons worth of fish, so plenty room for the fish to keep their space from each other. edit: if the two fish can live together what would be the recommended amount of neon tetras for the school?
