That's a lot of fish in only a 60 gal. Judging by the pleco it's likely going to outgrow that tank. Pleco's also poop A TON. Like I said, clowns need groups. And yours will get quite big. That's a rainbow shark. Some will lean toward docile, others are little territorial nightmares. I would be careful.
To sum it up I would rehome the pleco to a larger tank or to someone who has a large tank. Clown loach the same because they need groups and will outgrow your tank. Watch out for the shark they are territorial.
