Tetraodon: Greek, tetra = four + Greek, odous = teeth
Tetraodon miurus is strictly a fresh water species, no salt should be added to its environment. The water should be of high quality with high levels of oxygen and very low nitrogenous waste levels. The substrate should be fairly deep to allow the fish to exhibit its natural behaviour of laying partially buried. Don't use fine sand as this may compact and cause other problems, use river sand with a grain size of 1 - 2mm.
Good circulation is essential in order to keep the oxygen levels fairly high so a good power filter should be regarded as essential.
A simple layout with a few well rounded stones and some bogwood is all that is required, live plants won't thrive as they may be dug up on a regular basis but artificial plant could be included.
Wild Tetraodon miurus feed mainly on smaller fish, in captivity they will accept a range of live and frozen food. Snails, shellfish, prawns, earthworms, crickets, meal worms, blood worms, lance fish and krill will all make an acceptable diet.
Note, in the UK it is illegal to use live vertebrate animals (this includes fish) as food. The practice is cruel and unnecessary.
Aggressive, ambush predator which will lay partially buried in the substrate ready to snatch any prey item which passes within reach, Tetraodon miurus should therefore be kept alone.
There are no known external differences between the sexes.
This species has never been bred in captivity.
Tetraodon miurus is a relatively common species across a large range. Congo puffers face no major threats.
The colour is extremely variable with this species and common natural colours include brown, red or even yellow or green.
