I got this dude when he was a scrawny 2" thing. He's hit the 5" mark and become a real handful.
He used to get into it with my red tail but they've outgrown it. Now he'll get testy when the ropefish get in his way. They love rubbing up on the other fish. He stole a guppy from my larger rope but they don't get too crazy. Quite a little character.
I have a little zodiac loach that's taken to sitting on his back.
