Yeah I have to agree on the first one being hybrid. But I do think that the S. resupinatus are both resupinatus and not galinae/eupterus as both of them have the small branches on their maxillary barbels.

Now the more I've spent time looking at this fish the more I've been thinking that could this still be a genuine S. nigrita? Any thoughts on this? The color has gotten more dark brown but the spots are still visible. I had to move the fish to another tank due to my S. zanzibaricus beating this guy ...

Today I received two Synodontis resupinatus from a hobbyist who was given them with an aquarium they had bought but did not want to keep them. Together with them was a third Synodontis that I was unable to ID from the photos I had received earlier. I think it is a hybrid, it looks a little like a S ...

Have you taken a look at the parasitic catfishes of the genus ? Just a blind guess, but your description reminded me of them.

I'm going of a lot by the description of Synodontis zambezensis on the book The Catfishes of Africa by Dr. Seegers. The fish is lead grey with a little hint of greenish brown, maybe best described as olive brown. All of the fins are of the same color as the body of the fish with markings, small ...

Took me quite a long time to do an update on this fish. Finally went through my camera roll and found these fotos. I also got an confirmation, years ago now, that this fish is actually wild caught and apparently somewhere from the Tana river. I have also come to the conclusion that he is in the ...

Looks a lot like , but I am no expert on these.

Isn't this one a ?

Yes the darker specimens are as well grandiops/multipunctatus, they just seem to be a bit darker. I've seen some equally dark specimens of grandiops before so it is definitely just variation between specimens.

Going through the Cat-eLog I noticed something weird with . The ventral view photo seems to show a picture that of a Parauchenoglanis sp. rather than a Synodontis soloni.

All the synos in your first post are either multipunctatus or grandiops, best way to tell them apart is to count the fin rays as you already know.

The fish pictured in your second post looks to me like a hybrid, because of its large eye (too large to be a lucipinnis) and white pectoral and dorsal ...

That does look like breeding, but those don't look like S. granulosus. These have white on the outer edges of their tails and black barbles.

All 20 of them are hybrids, between which species, I can’t tell for sure.

As Viktor already said it is a hybrid. And it is a hybrid between Synodontis eupterus and S. multipunctatus.

The yellowish dorsal and pectoral fin spines makes me think that this is Synodontis obesus.

Since noone else has given you an answer, I'll try to answer your questions to my best knowledge.

The recommended 500l is good for one fish but in your case when you want to breed these a bigger tank would be more suitable for multible inviduals as granulosus is know to be rather aggressive. From ...

That is S. notatus.

I am not a pleco expert but this isn't a Hypancistrus sp. and it looks more like Peckoltia compta to me.

This is also a S. ocellifer, and this is what the fish in the first post should look like if it had its missing fins.

That is a Synodontis ocellifer. Your fish also seems to be missing both of its pectoral fins and its dorsal fin.

I once had a chance to get a group of green laser corys but I turned the offer down... I am deeply regretting that decision now since those fish look stunning!

I just received, maybe a week ago, a Synodontis flavitaeniatus that is supposedly in his twenties and honestly he does look like it as well. I also have some other synos getting close to being in their twenties. But the oldest fish I have ever heard of was a 37 year old S. decorus. Someone in a ...

As far as I am aware Corydoras do have a swim bladder. And the deformation of the spine is caused either by a mutation or by an injury that has healed over time but has then left a kink on the spine.

Seems like it has something wrong with its swim bladder, also if I am seeing correctly looks like the fish in question also has a deformation on its spine, I don't know if that adds onto its swim bladder issue.

Sadly I don't think there is much to be done in this situation.

I think you are right with that Ambylodoras being A. nauticus. Other known specie from Iquitos is A. monitor but I think they have less markings than nauticus.

Had to do an other reply to post the pics of the Synodontis cf. zanzibaricus! Also I noticed that S. ruandae only has drawings as pictures on the site so if my pictures are good enough you guys can use them.

The fish sold as Synodontis afrofischeri were indeed genuine, but the fish being sold as S. victoriae proved to be a S. ruandae or at least the one specimen I got. Sadly I lost that fish few days ago because of a local heatwave, I'll attach some pictures of him here. The sp. "Kenya" seems to be ...

I'd say this is , but as Silurus said underwater pictures would be helpful to make the ID 100% accurate.

(Mod edit. Fixed typo in name)

Here are some more pictures I've got of him over the years. Although these pics are not the best for many reasons (mostly because they are taken with flash so they don't show the true colour of the fish) you can see some details like the fine spots on the upper half of his body and some of the ...

I got this guy about 4 years ago in a Nigerian import with a name Synodontis sp. "Nigeria". The problem is that I don't know whether the fish was actually caught in Nigeria and thus given the name sp. Nigeria or was it caught elsewhere and just imported from Nigeria. I don't remember all the fish ...
