Dwarf Puffer Fish

So I've always thought these fish are awesome and we saw some yesterday and my partner liked them and I noticed a few of you seem to have them! I always thought they were hard fish to look after but a few sites I've seen say they are easy!? I've also read they are happier in smaller tanks.

So what size tank do they need and does anyone have any care tips? I might see if I can convince my partner we need a bigger tank 

Dwarf puffers are some of the cutest little bundles of adorableness. 
I've read a couple of articles saying a minimum of 10L per fish, but as Fiona says, lots of space & planting to break up the line of sight to avoid territorial disputes. Mine are in a 125L tank and I mainly feed them on bloodworms (live & frozen) and pest snails that I pick out of my other tanks. The guy at LFS who keeps South American Puffers suggested giving them a prawn to nibble on. I tried, they weren't interested. I might try them again, and on some other seafood. They are messy eaters and need a bit of cleaning after meals, but it is completely worth it.

Do you still have the Edge, and are there fish in it at the moment? That is just about suitable for 1 dwarf puffer. But obviously with a bigger tank you could have more.

Or another Edge? Maybe the bigger one? They have the same footprint as the smaller one

Thanks for the links  It's handy they like hard water as the water here is super hard! I currently do a 50:50 RO tap water mix in order to reduce my water hardness as it has normally restricted the kind of fish I can keep! I wonder whether my Amanos are still a risk - they're massive shrimp I can't imagine a little puffer eating one but I guess if they harassed them enough it would cause problems for the shrimp. My Amanos were called 'XL Amanos' by the MA - I made sure to check they didn't have any claws so they aren't a risk to my fish as they're much bigger than my killi and so far so good!

My partner seemed happy with the idea of one in our edge but has outright said no more tanks when I said about a bigger tank! Humph! We're planning on buying a house in the not too distant future so I might be able to persuade him then about a tank but until then I'll do some reading and see if I can suitably house one in my edge. My remaining killi seems happy enough at the minute so I guess it'll be quite a while until I'll be able to get one though, makes it tricky knowing whether to buy more or not now as it seems a bit mean to leave him on his own!

Puffers are very curious fish and chances are they will peck at the amanos. I'd advise you have a plan B ready for the shrimp just in case. They love live brine shrimp so.....

Although they can be territorial they are also quite social fish so I wouldnt advise keeping just one tbh.

Hmm sounds like my best option is to get another tank then... I'm thinking that maybe when we do buy a house I can convince my partner to let me get a new bigger tank to make it 'easier to move', then I'll have to sneak the old small tank somewhere  I had previously planned to attempt a marine tank once we were in our own proper house but the costs and complexity have been putting me off  Hmm, now I'm more conflicted as I would quite like to attempt a nice community tank, but these puffer fish are so darn cute and sound like they need their own special tank! Guess I'll have to go back to the drawing board and have a ponder about what I want!

Oh Sue, those are some smooth moves     
Liking your style. 

I live on my own, so apart from one of my friends who is coming over today to help move a tank, and has been saying that he's worried I've gone a bit overboard with the fish, I don't have anyone else to consider. As a general rule the girls think it is fine and between the pets and the garden I'm fairly occupied.
However, if my circumstances ever change, I am making a note of that particular move and absolutely plan to use it.         

I have tanks in spare rooms, but it's not that good an idea. If you have to go into a room specifically to look at your fish, there's an inclination not to do so that often. As a result, I find that I don't get nearly as much out of those tanks as the ones in the living room, where I spend most time. Unfortunately, lack of space and electrical sockets means that I don't have much choice. In retrospect, I would now go for fewer larger tanks in a couple of rooms rather than more smaller ones spread throughout the house.
