What’s the smallest size tank you’d keep?

[Azedenkae]

Start over for my main tank? 40 gallons.

20g long. No smaller please. Lol
Starting a 3g cuz its the thing to do rn but ive also had a 10g before in my bedroom back at moms and it wasnt set up very long till i went to the 20L.
The 20L was a very succesful tank.

I have a 40 breeder now, before I had 20 long. If I had to due to space or something I could live with a 20 long, but nothing smaller.

Small space: No less than 55 gallons

Medium space: No less than 75 gallons

Large space: No less than 180 gallons

Mansion: Up to 350 gallons


At minimum I would want enough to keep a Clownfish pair, a pair of Centropyge, a pair of smaller damsels, and a couple other smaller fish.

How funny, I have one of those really tiny picos that aren’t even a liter. I haven’t picked my livestock yet

 

[Pntbll687]

33 long I had was really nice

I'd also consider one those 12g long ones, they are just sexy.

I ran a 5g for almost 6 months. I recently upgraded that to a 20g. I'm currently running a 40g and a 20g. Small tanks = small water changes. I'm good with that, lol.

If I started over....the same size I have now 29 gallon in a wall with similar sump. I could go smaller in that space with a 20 gallon which would give more side room for pump placements. The 29 is a tight fit now.

It would be SPS dominant since I haven't focused on that realm.

The smallest I’d do is probably 2 gallons. I’ve had tanks from 5 gallons to 200 over the years, and right now I only have a 28 gallon Nanocube. I would still probably have a larger tank if I didn’t have health issues and could keep up with the maintenance. I think if I get my health sorted out, I’ll probably set up a larger tank (I would like maybe a 180-220g cube). I’m currently thinking about setting up a 10-20g frag tank, but I’m not 100% on the idea yet.

I have a 75 but Im going to sell it and get a 13.5G

 

[ApoIsland]

After keeping a variety of sizes (16, 29, 40, 50, 55, 120) there is no way I would go smaller than 75 for my main display. Ability to keep multiple tangs is the reasoning behind that.

I am in the process of setting up a couple 2g picos though but I like fish too much to have just that as my only tank.

 

[Hermie]

10gallon QT

 

[drewwCh]

If I could start over, I'd definitely go with a minimum of 75 gallons. Have a 30 gallon right now and I hate the fish limitations and how you quickly run out of space for corals.

I had a slant-nose 7-gallon AIO once. It was fun. (actually there were two, one on each side of the fireplace, on bookshelves.)

 

[Laith]

I've been thinking about a nano AIO tank for my office for a while now. Just not sure I'd have the time to take care of it properly.

 

[Amps Reef Life]

Smallest? 20 gallon. I have a IM 20 drop off that has a pair of black storm clown fish and two Chicago sunburst anemones in it. It's one of my favorite tanks and I have a 210, 85 and 55 gallon in the house.

 

[BanjoBandito]

3 gallon cookie jar, it's actually empty now after I transitioned to the bigger nano....but it's just....empty. Might have to fix that.

 

[brandon429]

.5 gallon

 

[Zionas]

I’m not really into small tanks because I want more fish and some of my faves are larger species. Smallest I’d go is probably a 90.

 

[Just John]

.5 gallon

Holy cow!!!!
