This is a very rare fish that doesn’t show up very often. You need to be careful if you do purchase one, as small ones get mixed up with Titan Triggers because they look very similar when small. If you see the start of a mustache around the sides of the mouth, then it’s a Titan Trigger as Yellow Margins don’t have mustaches. A fairly shy fish that does better in FO or FOWLR tanks with aggressive fish, but not too aggressive.
