I think I will just stick to the puffers can you tell me about there care and if possible give me some examples of how to setup up a tank with decorations can you also include pictures if possible
I don’t have any pics of my old dwarf puffer set up on this phone.
This is my 36 gallon Amazon puffer tank:

I believe
djsaltynuts
has dwarf puffers currently.
For setup, the most important aspect is having a good amount of wood and rocks to make up caves as well as plants for cover and breaking the lines of sight.
For care, they like a neutral ph at around 7, moderate flow, and temps of about 74-78. Water should be very clean of nitrogenous compounds as puffers are very sensitive.
Foods should be made up of shrimp, bloodworms, black worms, and snails, as well as various small insects and larvae. These guys do not have the beaks of other puffers but still love snails. It’s a good idea to have a snail breeding tank (like the 15 L) so you don’t have to go out and buy them (pond snails are preferable for dwarf puffers due to their small size, avoid Malaysian trumpet snails which can break puffer teeth).
One of my old dwarf puffers:

I had 3 in a 5 gallon tank, the dominant one eventually killed the other two. I also had some otos (if I remember correctly) and rosy red minnows (harassed the puffers) which did well.
