There's already a little Senegal named Udon in there with him, so they'll be tank buddies barring aggression issues! I'm hoping the pair of parrots I have will grow fast enough to avoid being snacks, but we'll see.
I'm thinking either switching him to a 55 with Udon or else setting them all up a 75-100, but that really depends on what his growth rate is moving forward. And what I can get away with before my housemates finally kill me for all these tanks.
