Fish Names Beginning With R

Here's an overview of fish, from the dangerous red-bellied Piranha to the docile red aphyosemion, that begin with the letter "R."

Common Fish Names Beginning With R

• Rachow's darter tetra (Characidium rachovii): This bottom-dwelling Tetra likes to be around its own kind. It lives well with fish like Danios that dwell at the tank's mid-top but don't keep it with larger fish that are predatory.
• Rainbow cichlid (Herotilapia multispinosa): The rainbow cichlid can alter its coloring according to its moods. The background color is a lemon yellow to gold, and it has a horizontal black bar running from behind the eyes to the caudal fin's base.
• Rainbow copella (Copella vilmae): Copellas are unique as they lay their eggs on plants out of the water. When a female agrees to spawn, she positions herself next to the male. The partners then leap out of the water together and attach themselves to the underside of a leaf using the suction of their fins.
• Rainbow shark (Epalzeorhynchos frenatum): The rainbow shark is a good fish for a semi-aggressive aquarium, as long as it's the only shark and its tank mates are of a similar size.
• Rainbow tetra (Nematobrycon palmeri): Rainbow tetras are peaceful but can exhibit territorial behavior with each other. Keep them in groups of at least 10 to reduce aggression between males.
• Ram cichlid (Microgeophagus ramirezi): The ram cichlid is a popular fish for a tropical freshwater aquarium. While most don't do well in a community tank, a male and female pair can live together quite nicely.
• Rathbun's bloodfin (Aphyocharax rathbuni): Keep the peaceful Rathbun's bloodfin in a shoal of at least six. However, don't keep it with predatory fish or those with long fins.
• Red aphyosemion (Aphyosemion sjoestedti): This is a quiet and shy species and it will be intimated by more vigorous fish and out-competed for food.
• Red base tetra (Hemigrammus stictus): This peaceful Tetra that won’t do well with larger or boisterous tank mates. Keep them in a group of at least six, and ideally 10 or more as they prefer their own kind.
• Red-bellied piranha (Serrasalmus nattereri): These fish live in a huge school and spend most of their time trolling for prey. The red-bellied piranha is a freshwater predator that is dangerous to both people and animals.
