[edit] Alternative names
- Figure Eight Pufferfish, Eyespot Pufferfish, F8 Puffer
[edit] Sexing
- Very difficult to sex visually.
[edit] Tank compatibility
- Best kept in species tanks as this fish can be aggressive and will fin-nip and attack tankmates. While young they may tolerate their own species but as they grow and mature this becomes less likely.
[edit] Diet
- Must be fed with molluscs and snails in order to make sure the Puffer's beak will not become over-grown. Feed snails such as Ramshorn Snails and baby Apple Snails, can also be supplemented with Ghost Shrimp and bloodworms.
[edit] Feeding regime
- Feed once or twice a day.
[edit] Environment Specifics
- Although often marketed as a freshwater Puffer, this fish does best in brackish conditions with an SG of 1.005 - 1.008. Hiding places and dense decor is appreciated as these are curious fish. Can be transferred to either marine (saltwater) or freshwater environments after acclimatisation, but prefers low-end brackish conditions.
- These are very messy fish so their tank should be mature, well filtered and spacious.
[edit] Behaviour
- An aggressive active predator.
[edit] Identification
- The markings on this fish can vary, they have a short rounded body with a white belly and the base colour of the top half varys from brown to yellow to green covered with yellow lines and dark spots with yellow outlines. Also there are a few black spots that are outlined in yellow on the tail, body and nose.
