Danionella translucida

The smallest vertebrate on show in Europe? These little guys grow to 1cm, so that the shoal looks like splinters of glass suspended in the water. Male below and female above - you can see eggs developing in her abdomen. These fishes are related to the zebra fish and the other danios, but have no scales or lateral line and fewer bones in their skeletons.

Cracking photo there, far better than my attempts!
Out of interest had they fixed a couple of the tanks up? When I was there in April there were two big tanks out of commission, one in the corner and a Madagascan tank.

These photos came from my second attempt. The first batch were rubbish
The corner tank (next to the triple Amazon tank) was boarded up. There were 2 tanks for Malagasy cichlids on either side of the piranhas if I remember correctly, a single tank on the left had young adult damba, the double on the right had a single old pin-striped damba (perhaps the last survivor from the original import circa 1996).

That's a shame, hopefully it gets renovated over winter. I didn't realise the pin-striped damba was one of the originals, looked pretty old though!
