It would appear the new fish has quite the appetite. Today he fed well on a mussel nearly as large as himself. The end result is a somewhat enlarged stomach, as seen below:

If he climbs out of there then he will face the porky, trigger and two flat toothed eels, so I reckon it is in his interests to stay put.
Quite small and cute though:
