Pat fish dry with clean paper towels. Brush with butter and rub with blackened seasoning.
In medium skillet, heat oil over high heat. Sear fish on both sides (about 1 minute per side). Pour drained tomatoes next to fish; reduce heat and sauté tomatoes until fish flakes easily with a fork (about 5 minutes).
Transfer tomatoes to a dinner plate and top with fish.
