I work on a sewage works and a colleague found this fish near one of the tanks. It could have been flushed or dropped by a bird.
We have been trying to identify it and also work out why the scales (if they are scales and not bone) are intact.
It is currently a feature in the office but nobody has been able to identify it, the general consensus is that it is a baby carp.
Can anyone tell us what it is and why it is not a normal looking fish skeleton?
Any help with this office mystery would be much appreciated.

This looks like the Catfish, Hoplosternum littorale. Do a google image search and you will see what I mean. You don't say which country your sewage works is in but it is available as an aquarium fish outside its normal range of South America. It has been introduced to a river in Florida. If you are in the UK this may reprsent an invasive species and it may be worth reporting to the Ministry of Agriculture and Fisheries, sorry I have no idea how to do this!!
Thank you John.
We have googled it and that is definitely the fish. It is facinating that it grows armour, i must research it further.
We are in the UK, I image it is an aquarium fish that was flushed down the drain.
We are really pleased that our fish mystery or 'fishtery' has been solved!
Thank you again,

I don't think this is a Hoplosternum, your fish is too small and short bodied. It is more likely that it is a species of the genus Corydoras, a relative of Hoplosternum, and of the same family Callichthyidae. Corydoras are very common aquarium fish and there are several species in the UK trade. Almost every shop has at least one species in stock. Hoplosternum is much less common.
