Cetopsid of some sort?

Post by Rusty »

We picked this guy and a larger specimen of the same sp. up at the LFS for $6.00 each (they were labeled as "Baby blind whale sharks"!). Both of them were close to death, w/ a bad case of fin rot, but they are healing nicely. Now, the question is what are they? I was thinking Pseudocetopsis, but looking at the picture now, I'm really not sure.

Any thoughts?

Rusty,
Looks like the photos of Pseudocetopsis that I have, but it does not look like any of the spp. I have photos of. Great acquisition.

The small one is about 3 inches, and the big one is around 4.5-5 inches. Caol_ila, which atlas? Burgess?

Looks like it might be <i>Pseudocetopsis minutus</i>.

The larger one is about 10 cm. Fishbase, which as we all know is often wrong on sizes, lists Pseudocetopsis minuta as 4.9 cm SL. Is that wrong?

Interestingly, they can really leap!

The only other fish that looks a bit like these is Tatia, or Centromochlus (both Auchenipterids) but those have very small or modified anal fins; that one has a nice, long normal anal fin. It looks a lot like the Pseudocetopsis pics in the Wels-Atlas!
Those tatia's etc have serrated pectoral and dorsal spines. If it hasn't spines, it's a cetopsid!

Dinyar,

I was mooching about the Fish Division library today to try and better identify your cetopsid. Didn't find much, but I think <i>Pseudocetopsis othonops</i> is a much better candidate. Plus, it's about the right size for your fish.
