Not unless it's a zebra plec, which, having seen many photographs of very young zebra plecs, we're pretty certain it isn't!

(plus our two never interact and are still quite young).
The only other fish in the tank are:
1 x
Annamia sp. (been a lone fish for some time)
10 (ish)
Eirmotus octozona
2 x L46 zebra plec
2 x mature
Schistura balteata
Lots of
Sewellia lineolata
and a good sized group of
Sewellia sp. spotted......
Nothing new added in a long time, except the
S. lineolata fry from the baby tank - and there was nothing else in there (that tank was set up using water and media from the main tank only).
