+1 (emphatically) to all the "no" answers.
Also, just want to add that goldfish are notorious fin-nippers. Two speedy goldfish in with your slow betta is no match. Incredibly high stress level for the betta probably, and stress is a big contributor to illness & disease in fish as it lowers their immune system and makes them avaliable to host any sort of nastiness that happens to come along. And, lots of bad stuff already lurks in the aquarium and on the fish, but a healthy fish and proper environment (temp, ph, being handled properly, good diet, etc.) will keep the bad stuff at bay..... UNTIL stress comes along. You've already got that! It's a waiting game now.
Your dad's set up is just inviting an early death for that betta!
