Yeah. They pretty much have the same facial structure and their dorsal fins look alike also.
I had one in with my dats, he was a great tankmate till he got about 5" and started bullying my NGT. Thats a nono in my book, so off he went.
haha i see i havent really seen them before but i was reading a book with some pics and thought they looked super close didnt know where to put this thread
I have several Ctenapoma (acutirostre and kingsleyae) in with all my dats, they seem to all get along pretty well. A few scraps here and there but nothing serious.
They are very cool fish, very inquisitive just like dats.
