Sep 26, 2012 · What is the average adult size of a female betta fish? I have a female betta who is about an inch long (not including fins). I'm wondering if she is very young because she also still has "stress stripes" after having her for a few weeks. I know babies have those stripes for camouflage and then the stripes go away at a certain age.Status: Open.

In a review where 38–39 piranha species were recognized, 25 were from the Amazon and 16 from Orinoco, while only 3 were present in Paraguay–Paraná and 2 in São Francisco. Most species are restricted to a single river system, but some (such as the red-bellied piranha) occur in several.Family: Serrasalmidae.
The average size of a piranha is 6 to 10-inches in length however, some have been recorded to measure up to 20-inches in length.
