Red Phantom Tetras can look very similar to their Serpae Tetra cousin.  While both can have an orange body with black spot, Red Phantoms dorsal and anal fin tend to match the body color without any black or white tips. You can keep them in a 10 gallon tank, but push for a 20 gallon with larger groups. Avoid aggressive or territorial species or large fish with big mouths.
