Sorry for the delay - I was in mourning yesterday (actually I was at Paignton Zoo and then working on my next batch of scans). This Asian species is one of the smallest in its family. Perhaps for that reason, it is the easiest to breed in captivity. Otherwise it has the same characteristic dentition, specialised diet and unique behaviour as its larger relatives. There is no photo of this animal in our Gallery, but it has a page in Zootierliste. Alan
It's the bit about it not being in the gallery that I'm struggling with- I was going to guess Pygmy Slow Loris, but a quick search revealed several pictures. Perhaps green-spotted pufferfish?
Really struggling to find species that fit the bill but aren't in the gallery! Lesser/peacock spiny eel?
Macrognathus pancalus is a very good choice, which meets the criteria well. Unfortunately it is not the species I have in mind. You were very warm, but you're getting colder Alan
I don't think it's ever been bred in captivity. But Swampy has hit the bullseye The answer is the Malabar dwarf puffer, Carinotetraodon travancoricus, which is much smaller than the previously mentioned puffers (little more than 2cm standard length). I will celebrate by posting a photo of a pair than I used to keep as they were spawning in a clump of Java moss. Well done Mr S! Alan
Thanks gentle lemur. My species is one of two in it's genus, but the only one to have been kept in captivity. It's binomial name suggests it is not in need of a manicure. It is found in four countries, and is the only member of it's family in two of them. It, too, is not featured in the gallery.
I have an answer that fits (although it may be like your spiny eel, a perfect fit - but wrong). How about the Madagascar clawless gecko (Ebenavia inunguis)? I think it meets all the criteria, but I couldn't get close without your manicure clue. Alan
