1 December 2016, at The Deep, Kingston-Upon-Hull. In a Mekong display. I apologise for the poor quality, because they are so small and fast, as well as the fact I'm a poor photographer it wasn't very easy!
I don't seem to recall seeing these before here, but now looking at my notes from a previous visit I see I have them written in. I thought the Bumblebee Goby were in this tank, but they must have been in the one that now houses Figure-Eight Puffers. They really need better signage in 'Deep Blue 1'...
