Betta Fish: 75 gallon tank overkill for one betta?


I have a 75 gallon tank previously from my hamster zaya, she passed a few months ago. I’m not ready to have another hamster yet, but i’ve always wanted a beta. My boyfriend is worried that i might be overkill, and stress the betta out. Thanks alot! All help is appreciated!

    I agree that it’s overkill but I don’t think it would stress the betta out. It would probably be very happy with all the space!

    Long finned yes, short finned no

    Edit: more suited to a short fin. They’d have a hell of great time in there

    If you’re looking to house a pair I’d say a 55 gal is plenty big. I have a pair in a 29 and they do great. To each their own, if you have the space why not!

    You can add a community fish that’s good and peaceful for the betta. Maybe get either a female betta or a male betta with shot fins.

    All i can say its make sure its a tank meant for aquariums. If its a reptile tank its not made to withstand the pressure of 75 gallons of water

    My dad told me many times when I was a kid that if you use a tank for gerbils, hamsters, etc. it’s forever ruined for fish. The urin and stuff won’t come away from the silicon, plus it (and the gerbils) can damage the seals. I’d leak test it outside at the very least.

    You’d have to plant it very heavily, and even then, it depends on the betta.

    I have actually done this; I had a lovely female who lived in a 20 gallon. I got a 75 gallon and, once it was cycled and set up, thought she’d appreciate the extra space because she had always been very active.

    She went from royal blue to grey almost immediately. Wouldn’t stop stress striping.

    I gave her a week to see if she’d settle in— I’ve had to move her between tanks before, and she would always get stressed the first few days— but when there was no improvement, I took her back to the 20 gallon and she went right back to herself.

    I compared water parameters between the two tanks and they were the same save for a very slight difference in pH— the 20 gallon was a little bit more acidic than the 75.

    TLDR; You could give it a go, but have a backup plan.

    Short finned will do fine and you can add community fish such as tetras, rasboras or Cory catfish to make it less empty. Bettas are really only aggressive with other Bettas.

    It’s a little big but if you fully fill it with plants and decor it should be okay!! I just don’t know if I’d risk it if the tank was used for anything but fish. Sometimes you can even do a community tank since it’s so big. My friend has a nice 35 gallon with a betta and some otos and kuhli loaches.

    I had a 36 gal with a king male betta that had the zoomies and was living his best life going back and forth. I WISH I had a 75 gal.

    You are just going to kill your betta.

    Bettas evolved to live in small rainforest puddles with just occasional encounters of the opposite sex. Females were bred and died, males tended to the young, and the rain moved the young to new puddles.

    They are not a deep-water species and find it hard to live that way. They won’t find your food and can’t sleep on the bottom. They need to fill the channels in their heads with air. Tank filters make currents that are too strong and make them waste all their energy swimming.

    These fish evolved to live in stagnant pools as small as a hoof print in the mud in the rainforest.

    Get some Wild betta antuta. They can be stored in small groups. They’re bigger than your normal betta and would love that size of a tank.
