    • This species is not easily sexed. The females when mature are slightly larger, but this only holds true for fish raised together. Statistically, if you have 4 or 5 fish you have good odds of having a pair.

    • Most fish are Hermaphrodites... Er.. The fish start out their lives as females and the dominant fish in the group changes sex and becomes a male. This transformation does not always occur in the aquarium and if you truly want to breed these fish you are best off finding a mated pair in a fish store. A mated pair could be expensive because not all fish will form a mated pair which means one usually ends up killing the other...I am not positive this is the case with Figure eight puffers but it is the case with most Brackish/Marine fish.
