Hello. Its nice to hear you are upgradiing your tank.
The only things I have to say are that adf
do not always do well in community tanks because it can be hard for them to get enough food. Some people have luck with it, some don't. Up to you.
I suggest only getting like 3 otos to start with. They do best in well-established tanks, so wait a bit to add them. If you start with 3, you can see how they do and then consider adding more if you want to.
