I have a 50 Gallon community fresh water tank. I have a large variety of fish in it which includes 4 tiger barbs, 2 mollies, 1 Platty, 1 dwarf gourami, 1 guppy, a rainbow shark, a spotted puffer, and a peacock eel. When i first got the tank i was worried about putting my puffer with my guppy together because i heard puffers nip at long flowing fins. But i had also heard that if the tank is large enough they will more than likely be okay. I have had the tank going for about 4 months now and all my fish get along. I was wondering since my i have such a large tank would a betta and puffer be okay together?
