Bought 3 of these not realising that syno's are known as upside down catfish. I looked at Synodontis nigriventris which has the common name Upside Down Catfish but the pictures look different to my fish so im assuming mine are not this breed.

Any Ideas

Hope the quality is ok.

Regards and Many Thanks In Advance

Hi!!

Not so sure they are not tank raised... the region near the dorsal fin hard ray look really diformed...

The color pattern indicates that this is a juvenile (this form of juvenile color pattern is common to many species), so it may be necessary to wait until it grows bigger to tell for sure.

juvenile or no; definitely NOT a nigriventris.
those look the part -including the black belly and the telltale tiny white spots- at sizes even below 1".

my vote's on hybrid as well.....

Now 8 months on and I ask again any ideas this fish is now 120mm long I still have all 3 the one in the pic is 120mm long another is 80mm long and the other is still 50mm long the latter only a shade larger then when I got them. Buy accident I came accross a website that was selling Synodonts Eupterus which I thought look like these could be the ones. Anyhow here is mine

The pectoral fins look unusually long for S. eupterus. I suspect you have a hybrid.

S.Eupterus. NOT A HYBRID....

Def S.Eupterus, aka featherfin catfish

All I can add is the hard spine on its dorsal fin only runs about two thirds the length of the fin and then the rest is like a soft tassle

This is still a young fish at this stage so lets see.

I have managed some better pictures of my suspected feather fin syno





does this help better ID it

Yup, it's a regular featherfin.

Just thought I would post a photo update



Its now 4 months since the last pic and its fins are really developing with a nice long tasle on the dorsal fin

That is a really good looking Eupterus..or maybe an average Eupterus that you are keeping in fantastic condition

very handsome syno.

How are yours getting along Andy I remember your thread when you first got them and then again when you were putting them into a larger tank

Mine seem fine, thanks for asking, Colin.

I have so aqua scaped their tank that I cannot even count them anymore on a daily basis.

I can see eyes and fins moving and I know there are five still but I do not really see them unless it's sand tilling, vac'ng all sand time or it's feeding time. Even at feeding time they are pretty much swoop and run. But I love them.

My two oldest are probably 5 inches my next two are prob 4 inches and my youngest is prob 3-4 maybe. The youngest is the slenderest and a slightly diff colour. I am thinking I have 4 girls and one boy but I am not sure. The only time they swim the tank is when I am not in the room or at work so it's hard to capture their bellies against the glass for a picture. If I sneak in at night after work and use a flashlight I can see them swimming all over all water levels but soon they discover i am there and take cover. they peek at me from behind things and wiggle their whiskers.

I will try to get pics of all 5 so you can see tho. And they really like the bigger black ABS pipes best. Altho they do go into the white pvc and they are all over the driftwood.
I havent had one by the heater or intake tubes in quite awhile.

I noticed you asked about acintic lighting well that is what I use but I dont point the light directly into the tankl and mine are very active I'll try to take a pic without the flash so you can see but mine are in with other cats also.

yeah i would love to see the pictures.
