Oh shoot.
If your tank is only 35G I see
possibly a few potential issues you should be aware of. They may be okay, but with these species you're prone to certain things happening.
2 ocellaris
1 ywg
1 firefish
1 neon blue goby
1 fridmani
1. Firefish are super jumpy, and Fidmani are super mean.
Your firefish mostly are going to hang out in the water column, and your fridmani will establish a "territory" among the rock work.
See photo of your tank I ghetto photo edited below. Your fridmani (Purple) is going to be about that big, and your firefish is gonna be that big, swimming around. If your fridmani feels encroached upon he may nip at your firefish, which are very known to jump, so I would ensure you have a screen lid. Additionally it might overstress the firefish out eventually leading to death.
2. A blenny also will try to find refuge in the rockwork. With such little amount of rockwork, the fridmany
MAY find it hard to share the space.
3. Neon blue gobies are quite small, and very possibly that fridmani will try to turn him into a snack or bully him to death as well.
this isn't a gurantee'd but that small space it is a high possibility i'd say 40%.
the common denominator in all of those is the fridmani.
IMPO i'd skip him and go for a blenny, then you'd be much safer
