Can you put a Orange Von Rio Flame Tetra and guppy in the same tank?

No, Orange Von Rio Flame Tetras and guppies should not be kept in the same tank because the water temperature requirements for these two species are different. Orange Von Rio Flame Tetras prefer water temperatures between 72-82°F, while guppies prefer water temperatures between 75-82°F. Additionally, Orange Von Rio Flame Tetras are known for nipping the fins of other fish, so they may bother guppies.
