@ros77uk thank you for being so understanding, and I am also relieved that you chose to do research on fish prior to any purchase, something we would always recommend that people do.
We all go through the disappointment of finding out that a fish that we like is unsuitable for us, for many different reasons. It still happens to me on a regular basis, and I'm often found searching the internet on my phone whilst staring wistfully at a tank of fish in a shop.
As for dwarf puffers, if you do decide to get one it will provide you with hours of entertainment as it explores the tank, being distracted and amazed by every little thing. From a distance they look as if they are floating slowly around the tank, but closer up you'll see their little fins going like the clappers. They really are quite comical, until they turn their big puppy dog eyes on you to beg for food, then they are just adorable. You may have to learn to be firm in resisting this look, and it is quite difficult not to overfeed them.
As I mentioned before, the final decision really is up to you, and we would love to hear how you get on.
