Tetragonopterus Argentina

[Keys_to_Adventure]

So lets get into the meat of this! I have an attempted biotope in the making, I have 3 (soon to be 5 or 6) Tetragonopterus Argentina and a Red wolf fish. I have noticed one specific Argentina has much larger scales, larger mouth, even eyes than the other 2 in my tank currently. He has no aggression or interest in food, and is being bullied profusely. The other 2 are monsters in feeding and attitude just like my amazing LFS said they were! Everything Ive looked at or searched has come up black with only minimal information available. Can anyone whos kept these beautiful fish shine some light on this for me? (Sorry bout the scratches on the glass I got the tank for next to nothing! I’m upgrading to a 75g soon)

I had them years ago and they were are you said, non aggressive but fast feeders. They are a really cool fish.

After adding another 3 the larger of the now 6 is MUCH more aggressive of a feeder, But all still extremely skittish. IM about to add a ton of plant cover to keep them a little more happy.
