I bought it yesterday. It's a brilliant yellow-green colour all over. LFS didn't know what it was. They had it in a Rift lake tank, where it was busy bossing around the multipunks and cichlids. It's very active and started feeding right away.

I'm fairly sure it's a Synodontis macrops, going by a photo of that species in the Burgess catfish atlas. Has anybody kept one, or can link me to more photos? It's listed in the Cat-eLog, but there's no pic.

I think the "S. macrops" in the Burgess book is a young S. schall.

In Poland hybrids are often sell as green synos for about 1$ - they are silver when young, then they get very attractive colouration - look at <a href="http://www.planetcatfish.com/catelog/mo ... p">this</a> fish.

S. schall was my next best guess. Do they sometimes have yellow or green coloration? The colour of the critter is exceptionally vivid; it is practically fluorescent.

Is there an easy way to tell them from macrops?

Synodontis macrops, as its name implies, has a large eye. IIRC, it doesn't look similar to S. schall, having a larger eye and more slender body.

The only neon-green synos I've ever seen have been hybrids.
E.g. this Synodontis "sp. 3" sold as Synodontis multimaculatus:

It was iridescent green - the white balance is not off. Others have reported czech synos which were bright lemon yellow ( http://www.zpet.se/medlemsbilder/data/5 ... CT0029.JPG ), or which had blue fins.

Does it look anything like this fish? It was all-over yellow as a juvenile too, but more greenish at 9" TL now..

If I remember right, HH thought it might be S.resupinatus

Yes, that is extremely close; my fish is more green, but I bought the biggest and greenest specimen out of a group.

One possibility is that they're some kind of albino.

I think that second one of Mike Noren's pics is possibly Synodontis adobephotoshopus.

Chrysichthys,
Is this close to your fish?
This is the only greenish(slightly anyway) yellow Synodontis I can think of.

I believe HH had ID'ed this fish at some point on these forums in the past.

Silurus, you remember which species you thought these were?

Synodontis rufigiensis, I believe.

this one looks really yellow in the right light
S.obesus(?)

No, mine is deeper-bodied, has a bigger adipose fin, and no markings on the tail.

It isn't the obesus either. It's the one DeepFriedIctalurus posted. Silurus, you reckon that one is Synodontis resupinatus?

TTBOMK, yes.
