Rob Posted February 10, 2005 Report Share Posted February 10, 2005 How long have you had the fish and what size is it? It doesn't have the colouring I'd expect of a true upside-down cat (Synodonits nigriventris). It looks more like a juvenile featherfin syno (S. eupterus) - they start of with a black and white squiggle pattern and has they grow get a dark spot on lighter background pattern with fin extensions from the dorsal fin rays. If it is a featherfin it should get to about 20cm long. Quote Link to comment Share on other sites More sharing options...
Billaney Posted February 10, 2005 Author Report Share Posted February 10, 2005 I've had them a month or more and have seen on many occation them swimming upside down so i'm pretty sure it is an upside down catfish, the pic is a little dark, the light color is a soft golden color with darker marking Quote Link to comment Share on other sites More sharing options...
Rob Posted February 10, 2005 Report Share Posted February 10, 2005 All synos will swim upside at times and many shops will label any type of syno as 'upside-down' for this reason. A true upside down cat should look like this: Photo curtesy of Scotcat Quote Link to comment Share on other sites More sharing options...
catfish_dude Posted February 10, 2005 Report Share Posted February 10, 2005 i also think they are juvi featherfins. i have 4 juvi synos that i'm growing up at the moment.. 2 of them are growing like there is no tommorow (they look exactly like yours, and i believe mine are S.eupterus). but my other 2 haven't grown too much and they have quite different patterns, so i am hoping they are true upside downs..or some other syno they were sold to me as upside down synos, but at $12 each i was highly doubtful, but that is a good price for any syno imo.. so what tankmates do they have..my huge one (not a juvi :lol: ) is quite boasterous at times and i don't think your average community would care for a rampaging pair of 7'' featherfins Quote Link to comment Share on other sites More sharing options...
Billaney Posted February 10, 2005 Author Report Share Posted February 10, 2005 here are some more pic's , if you are right , what size do they grow to and are they ok in my community tank ? I got them from Animates in wellington , there still on sale there as upside down catfish i saw them today. Quote Link to comment Share on other sites More sharing options...
CatBrat Posted February 10, 2005 Report Share Posted February 10, 2005 I'm pretty sure that those are Feather-fin Syno's. In pet shops they are normally always sold as Upside Down Cat's when they are young and are normally about $12. They will get to 20-25cm (well thats how big I have seen them). How big is your community tank? Mine was fine in my 4' community tank (until it broke), where it grew from about 5cm to 17cm in about 2 years (maybe a little less). It didn't bother any of my small tetra's, but at a larger size they might. Hope this helps....... Cheers, CatBrat. Quote Link to comment Share on other sites More sharing options...
Billaney Posted February 10, 2005 Author Report Share Posted February 10, 2005 the pair of them are in a 200L tank, doing good and don't seem to be a hassle with any other fish. its wrong for the shop to sell at one thing when its another , surly the supplyer/breeder knows the differance.

catfish_dude Posted February 11, 2005 Report Share Posted February 11, 2005 that is why scientific names are so important. the family 'synodontis' are often called upside-down cats, and synodontis nigriventris is 'the' upside-down cat.
