its about 1ft or a little more. these are the best pictures I got. It has many smaller spots in rows and some almost look like dash marks. it just started coming out more frequently, but not that often. It's hard to get good picture of
Most mastecembalus and macrognathus eels will get close to 18inch in most home aquariums. With exception of a half banded spiny eel as this is most commonly seen. There are a few others but rarely seen.
I have a starry night eel (Mastacembelus frenatus possibly) in my 33 as a grow out. How long until it gets some size and can be added to the 150? It’s about 6in and is as thin as the stiphodon gobies I have with it right now (eel is temporary)
