Datnoid with this stock?

[TheEelKing]

Hey, all,

I have a 180 gallon tank. So far, here is my stocking:
1x severum
1x blood red parrot
1x leopard ctenopoma
1x black ghost knife
1x fire eel
5x clown loaches

I want to add 2 more fish (if possible) to finish my stocking. I want to add a flagtail and a datnoid. Will this work long term?

i've seen dats with everything on your list except the perch. guess it depends on how big ur dats gonna be.
