Lost a fish

[BCReefer]

Today is a sad day. I found my 5 month old firefish laying on its back behind the tank. I have a big hood that goes all the way around but I have 2” in the back to allow airflow etc. I can’t put apiece of wood in the back since I have my wire and a hang on skimmer.

I am very sad. Can anyone please over me some assistance in how I should cover the back? I know of crates and mesh but shouldn’t the mesh be plastic, not metallic? I guess Revy or HD will be my best bet.

I think he jumped since I changed the tank 2 weeks ago and his hiding place was moved.

I am going to buy some more rock and add the mesh then when the rock settles I will add another firefish. I really liked him. This is my 1st causality since 1 screwed up in the beginning going to fast. I have taken my time and read. I knew that the firefish could jump but I usually give him good hiding places and the back is half blocked.

Thanks for the help.
