Red Congo puffer
Scientific name: Tetraodon miurus.
Origin: African; Congolese.
Habitat: Often found on the base of very fast flowing, clear or turbid streams and large rivers.
Temperature: Keep between 24-28°C/75-82°F.
Water parameters: Completely freshwater in origin, pH of 6.8 to 7.6, hardness 10 to 16°DH.
Diet: Fierce carnivore and predator. Chunks of fish, earthworm, cockle, mussel, shrimp, and snails.
Sexing: No external indications.
Aquarium: A solitary fish suited for a species-only tank. Use a set-up with fine substrates, cobbles (which the fish will pretend to be one of) and branches,
and a strong flow of well oxygenated water. Koralia pumps, or even a river manifold are both good ideas.
Notes: This will devour any fish it is kept with and it is ill advised to place alongside other species. It is particularly hostile towards its own species. Be careful when maintaining the tank, as the powerful beaks on these fish can cause damage to any unattentive aquarist.
Why we like it: Congo puffers are fascinating curios at the best of times — but the red markings truly set this fish apart, as both something that likes to hide away, yet can be frequently seen in the tank. It is a superb character fish for the species-only aquarium.
Availability: Seen at Seahorse Aquariums, Dublin.
