After reading through some of the other sections, i came across this post - http://www.planetcatfish.com/forum/view ... 37#p128851 from Marc stating that Centromochlus altae is now a valid species. When I purchased my Tatias, they were sold as Tatia altae, which I had read was a synonym of . I was wondering if there is any way to determine differences between the two? I'm happy assuming I have but was just interested.
Thanks

If you still follow the posting you are refering to, you've found a "theory" that could make sense and - if correct - would imply that the fish in your avatar could be a male C. altae.
However, the theory is of course not scientifical - it's merely an observation - so I wouldn't put any money on it .

Yes, I have been following the post
Personally, I wouldn't have said mine had large blotches, but without having any other fish to relate it to, I will happily take your word.
Will try and get some more shots of my fish at some point to check they are all the same. It also means I will have to be more fussy when I get to go back for the last pair I intend to buy!
Thanks again

Hi Chaps

The theory of big spots = altae and small spots = perugiae has been around for some years now. I seem to think that Klaus Dreyman had an article on it on the net some years ago. I'm not convinced if it is reliable.

The best way is to find out where the fish were caught. If they are from Peru or Ecuador they are likely perugiae, if they are caught in Colombia they are likely altae.
