we had two baby gold tulip eels (the wholesaler called them exactly that) at my lfs about a year ago, they didn't last long though, they were about 6-8" long each. Cool looking, but someone put some green terrors in their tank the next week and I found them shredded the next day. Too bad, I had no idea how rare they were.
Mine is not likely to be synbrachus, they are not native to my country or region, and as i mine was wild caught. I know the picture didn't show its tail, but it has a very tapered tail.
Most of the swamp eels here has a narrow head. here is a link that shows the general configuration, its head is also said to be like the head of a dog. There really are alot of different asian swamp eels such as belonging to the family of Ophisternon, but mine is not those, its the common type.
Guys, I just got six of them (at 8"-12" long) and I plan to post picks soonest. They're still in qt and I'm trying out different foods. Can anybody suggest food items for them? Tnx!
