Hi,
My son caught this fish in a nearby freshwater stream. Water is fresh to brackish. Other fish in the stream include tilapia, banded jewels, pleco catfish, etc. It's now in our fish tank and I want to have an idea of how big it will get, have him Google it to see how to care for it.

Thanks!

Where do you live?  We take questions from all over the world, and your community information (pleco, banded jewels, tilapia) suggests tropics, but they are all introduced widely.
