How big do Gold Spilo's get? I heard around 9" but didn't know if it was the truth.

 

[SnowCichlid.]

If you are reffering to Serrasalmus Spilopleura then they will reach a range of 7-8 inches in length as an adult.

They dont get very big, They are the smallest piranhas besides irritans. correct me if im wrong but I dont think i am.

11-12"

 

[hydroshutter]

I've heard people with 10inchers but it'll be very rare to see one larger than that.

The largest I've seen was 10in. They certainly look like pygos when they get larger.
