He's camera shy, but you can see his three new tankmates, red GloFish (I asked for Neon Tetras, but whatevs, they're cool too.) So far the only "aggression" he's shown is chasing after them and wandering off after about a half-second. He doesn't flare up, so I think he's just entertaining himself ^^ And they get along at feeding time, though yesterday he got a bit confused and I think didn't get all his pellets, so went after the flake food instead.
But yerp, they all seem to be getting along :) He gives them looks, but doesn't flare up or attack.
And edit, the tank water is a lot cleaner than it looks! The blue of my wall combined with the camera flash gave it that icky-ish colour. And if you look pretty careful near the filter and heater, you can see Milo's fins. And ughh, I can't get the top suction cup on my new heater to stick.
