Telling apart Synodontis eupterus and nigriventris
Posted: 11 Feb 2019, 07:13
Hello everyone,
Over here in South Korea, the most common Synodontis is eupterus. Heck, if it is just named "Synodontis", chances are it is 99% just eupterus!
The only other relatively well known species are lucipinnis (as petricola) and mulpitunctatus(The beautiful cuckoo catfish).
Some places sell hybrid synos too...and every now and then I see a chance angelicus. But never the original upside down catfish, nigriventris! Nuts huh? Evem though they are smaller and more peaceful! Maybe eupterus are better bred in huge numbers?
I have seen my fair share of eupterus, but last week I stumbled across what I am fairly sure are nigriventris. The little cats were with a few ture baby eupterus, but somehow they seemed different....But since I have never seen a live nigriventris before I cannot really tell.
Can anybody give me a surefire way to identify between the two? As I said in Korea Synodontis are not popular so I have nobody to ask here ...maybe there are subtle or definite differences in coloring, spots, head shape, fin shape? They were way darker than usual eupterus juveniles, but based on my experience young eupterus do not have a big difference in the dorsal fin(which will grow to be big and beautiful) I got confused.
Can someone please help separate the two? I am kicking myself since I did not take pictures at that time After seeing way too many baby eupterus I think I have gone paranoid!
