amatitlania id?

Post by fishop » Thu Nov 17, 2011 6:44 am

can anyone help me i.d. these little ca cichlids?

i think they're amatitlania.. supposedly f1 from adults originally collected by barry mckee.. i have no location info.. they're nice, red/brown tail, and orange dorsal and anal fins.. a little blue in the throat (but not nearly as much as my honduran red points)..

Potentially beautifull species but I think it's a Cryptoheros sp :lol:

I'm not convinced that the different geographical forms of Convicts really merit specific status. Be that as it may, but if the classification into several species is applied, I would say they are A. nigrofasciata in the strict sense.

I presume you mean in the broad sense;) Without collection information (or detailed phenotypic measurements) you won't be able to get a good ID. Considering the coloration of the male though, I feel somewhat comfortable in guessing that this is a population from northeastern Honduras (A. cf. siquia based on my own data, the A. nigrofasciata from the Pacific drainages look different). But I'd be also very happy to be proven wrong in my gut feeling. The species status of fish from that region is anything but clear.

Just for a comparison:

What I think is A. nigrofasciatus s.s.:

What I treat as A. cf. siquia (HRP region):

thx for the replies..

i have recently made contact with barry mckee and he says that these were originally collected just north of tortuguero, costa rica in "a 'puddle' that was evaporating in the dry season"

he refers to them as amatitlania siquia "red" because of the very red tail.. collected in 2003..

michi, your picture of the cf siquia looks similar to the fish in question.. here's a pic of the third male i have.. similar spotting in the fins and colour in the upper half of the body..

i'm really not up to date with the classification debate.. would like to hear ur opinions now that i have found location information..

thx,
brian

They look great!

Here in MN, the LFS has a large breeding pair that look similiar in color to your pair, but size is larger and bulkier. Has the orange/brown tone to it as well. Almost copper like.

No Michi, I actually meant "in the strict sense". I find they fit better to A. nigrofasciata with regard to body depth (as far as determinable from a photo) and color pattern, e.g. the caudal spot seemed not to be extended onto caudal peduncle. However, now that we know the place of their origin, it is clear that I was wrong. The question is, what are species worth which are apparently identifiable only by locality data.

If they're from Costa Rica would they be A. siquia?
