Oscars probably yes, as long as they can settle the dominance thing quickly, angels, probably not a good idea. . . IMHO. Pick up the pikes and worry about the rest later Oh yeah. . . show us what they look like!
agree with big pic. get the pike. and then if the others work they can stay. if not then they have to go. xingu 1's are sweet looking pike. if i have the space id get one. and an acutirostris, and a cobra, and so many others.
