Cheers pal, and it died about 15minutes ago

It would still be information others could use - so - please - answer.:)

The bottom line -

1. If a fish is on the bottom of the tank breathing heavily - act quickly. it's unlikely to survive.
2. Really sorry about the fish.
3. Again welcome to R2R

Welcome 2R2.
You post the tank is new.
Is that “new” or “new” but cycled, the former could be ammonia poisoning and the temp not great for keeping oxygen levels, if you have no inverts, drop your salinity to say 1.020-1.023.
Sorry for your loss.
