55G stocking suggestions

[Brine]

I just upgraded my 23G planted to a 55G.
Currently housing 6 Cardinal Tetras, 2 Otocinclus, some wild strain Neo Cardina and 2 random ADF.
The frogs are going to be rehomed.
The upgrade came with a 46 inch JC&P light with 3 strips of LED. I can't seem to find any information about it.
Got some Fluval Stratum substrate and some plants.
I'd like to go planted but I can't decide on what to stock given that stock can be hard to get right now.
I'd love to get another Carinotetraodon Irrubesco but they are hard to come by.
Perhaps an Amazon Puffer of some kind? Apistogramma? More Cardinals? Some form of Pleco?
What do you suggest?

You can probably contact JC&P.  They are based in Toronto I believe.

Great suggestion! I've sent them an email.

I've personally had no luck finding Amazon Puffers around here, but if you find any, let me know!
