Choosing a medium size aquarium: Is a 70-gallon, 100-gallon, or a 130-gallon the best mid-sized reef tank?

75 gallon is the best imo, its the cheapest and big enough to open a lot of options with fish yet small enough to not take up to much space in your home.

48x24x24 120 gallon imo is about the perfect starting mid size

this is my favorite size as well!

I personally do not see a tank over 70 gallons as midsize. To me something in the 40 to 65 36” long tanks are midsize. In my opinion a 36” x 18” x 24” 65g makes the best mid sized tank.

I voted 130 gallon because it was on the list. In terms of mid sized (IMO), I think 70-gallon falls in that category the best. 130 or even 100 is a bit large for me to consider mid-sized, but a lot more stocking options open up at 130

How much weight can your floor support?

40-75 imo are small tanks when we are talking saltwater, below 40 is a nano, and anything longer than a 4ft tank is large. I know a 125 can come in a 6ft tank, but that’s more floor space needed and swimming space for larger fish. Just my 2 pennies worth.

Moving from a 60 gallon AIO (36lx23dx16.5h)to 90 (48x18x24) in the next few weeks. Love my SR60 but I’ll enjoy the extra space.

60 g breeder love the size

In this category size tanks I am easily on the side of 36x24x24 or 48x24x24.

24 wide is important for inhabitants and rock work.

 

[gregdepot]

The cheapest options are 75 and 125 generally. I would consider a 125 to be large .

 

[Reefahholic]

24 wide is important for inhabitants and rock work.

No doubt. 18” isn’t enough.

This is about the best price you’ll find. I don’t think anybody can beat it by much. Only $55 to ship.

I feel like 6ft long is the perfect medium sized tank. I feel like it’s the sweet spot that opens up the fish you can keep without going insanely huge.
