stocking a 55 gal lightly planted

[Beowulff83]

Hello all i was wondering about some fish i am looking at stocking in the future in my 55 gal lightly planted tank. I curently have 9 Neon Tetra's and 9 glow light tetra's, 6 ghost shrimp and 1 pleco. I was looking at adding some marbled hatchet's, 3 or so oto cats. And for my main attraction i was wanting to get a royal farlowella cat. Would there be any issue adding any of theese?
How many hatchets would be recomended, and should the royal farlowella's kept solo or would it be better with 2 of em? Any advice is welcome.

I'd add 6 each of the hachets and otos, while skipping the royal.

since you already have a pleco in your tank, skip the otos.

get 6 hatchets.

corydoras would be a better choice for your tank because you can have more of them instead of just one farowella.
