Hehe...yes, he's beginning to dwarf his tankmates, that's for sure!
Absolutely!
Matter of fact, Triton just ate his first tiger barb tankmate the other day. He and the barb decided to dart for the same chunk of food during feeding time, so Triton simply gobbled up both the fish
and the food at once!
As for suitable oscar tankmates...in a 55 gal. (absolute minimum tank-size for a single oscar) there should be none. And yes, I
should practice what I 'preach', but currently I'm not doing that, lol.
In a 75 gal. (which I'll be upgrading to as my Christmas present
) you could get away with an oscar and 3 silver dollars. Perhaps even a pleco instead of the silver dollars, but not both. Most experienced oscar-keepers will tell you that a single oscar in a 75 gal. requires enough water-changes on its own, without any other tankmates...let alone a messy pleco. Still, I intend on having my oscar and pleco together, though I'm sure it'll require more water-changes. Really it all boils down to how dedicated you're prepared to be with regards to maintenance & water-changes, etc.
IF you jump to a 125 gal. tank size and beyond, then your options open up quite a bit as far as tankmates go. People have had different luck mixing oscars with some of the other larger cichlid species, so nothing is an ironclad guarantee to work. Two compatible oscars could survive long-term together. Then again, there's always the possibility that one turns on the other and they begin fighting...usually around the time they hit sexual maturity (which I believe is around 8"). I'm not sure what species have had the highest success rate when being housed in with oscar(s), but I know I've seen GT mentioned quite a bit. Truly I'm not experienced enough to give you as complete an answer as I would like to for this question, so perhaps someone else will chime in.
