What Fish in Downgraded Tank?

[ollysaquariums]

Hey all, I currently have a 4ft long 303 litre aquarium including sump and my cabinet has been annoying and the hinges are all detached and the wood is rotting (I bought it second hand) and I’m thinking of just downgrading anyway to a waterbox 20 cube or 25 cube, but I’m not sure what fish I could keep or not. I currently have a pair of clownfish which I will keep, a blue tang which I was planning on selling soon before it outgrows my current tank, a coral beauty, flame hawkfish, yellow wrasse and yellow coral goby. The clownfish have an anemone too so I don’t know how well that’ll go with the corals and stuff. What fish could I keep and what fish would need to go?

I'd get others to chime in as well, but my gut instinct is that the coral beauty and yellow wrasse will need to go. The flame hawkfish would probably be fine.
The yellow goby is the one I'd be most concerned about since I'd expect any aggression to be directed towards it.

As for the anemone, if you give it a well lit spot near the top of the rocks and give it good random flow it should stay put. I've got some that like to sit near the top of my rockwork and don't move for months on end. They typically only move if they split or I change the flow or rarely the rockwork.
