[RichNJ]

Looking for opinions on Trout Goodeid (Ameca Splendens) vs. American Flagfish.

Which is more aggressive and nippy?  Which is better at hair algae control?

While I have never kept goodeids, I have kept flagfish on several different occasions and currently keep them as well.  Flagfish definitely are nippy but are great algae eaters of hair algae from my experience, that being said keep them hungry so they will eat it though. If being fed multiple times a day they will not graze as much.
