Green terror

[Casey1234]

Hi everyone, just wondering if you could help me, there is a lump that is growing on my green terror, it’s pinky/white at the bottom near his stomach, I have put a photo on for you to be able to look at

Hi and welcome to the forum

It's either the ovipositor (egg laying or sperm depositing tube), or the fish has part of its intestine sticking out its butt. If it's the ovipositor it's nothing to worry about. If it's the intestine it can be an issue, but they normally go back in by themselves. Try feeding the fish some plant matter for a few days and see how it goes.
