My 100 gallon Oscar tank

That does leave it a little easier to look into tankmates that won't be eaten before they grow large enough.

I'd be hesitant to recommend clown loaches unless you were planning to upgrade to even larger than this tank size in the farther future (they're slow growing, but they can get massive and are schooling fish), but they're a possibility with some considerations.

Perhaps could look into striped Raphael catfish, or some of the larger synodontis catfish. Featherfins are lovely

Thank you, would a seachem tidal 110 and a large sponge filter be enough filtration for a 100 gallon with one oscar and a pleco in?

I'd go canister imo. Best mechanical filtration you'll get

I agree with that as I’ve always used canisters, but I’ve got a tidal 110 which is said to do up to 100 gallons and pushes 2000lph.
If I combine this with a large sponge filter, this should be good filtration for my single Oscar tank right?

I think you'll find yourself cleaning them frequently, they'll be enough, but may find yourself with more frequent work
