I also raise wild type Bettas.
Probably not almond but Terminalia catappa leaves.

Re: Cory Trilineatus and what else? (warning: picture heavy)

The first two images belong to the fishes with straight scutes junction zigzag, the eye above the lines shown in the drawing of the type specimen and head arched above snout I called false Corydoras trilineatus in http://www.planetcatfish.com/forum/viewtopic.php?t=17892 http://www.amergim.com/albums...

Yes, it should be labelled Corydoras sp. aff. sipaliwini or similarly regardless where it comes from. Otherwise the PlanetCatfish gallery will be a source of confusion. Curiously, in Scotcat gallery, the same picture is contained both as Corydoras bondi and as Corydoras sipaliwini . For me the galle...

We are slightly off topic. My starting remark proved to be well based and therefore the false Corydoras sipaliwini should be removed and replaced.

If these were imported I am sure you would be arguing that they are two separate species. By the way the growth rates are different as is the head and body shape. Ian, The head and body shape are fairly similar. I guess that the variant is the commonly encountered abberation in domestic animals the...

Perhaps we should call them Corydoras Epilineatus or Corydoras Trilioscopei :wink: I think it's just variations within the species...my humble opinion. You may be right, but I expected that experts are able to give exact answer. You can see that I hesitated to present my opinion, I simply presented...

The fish you show taken by Jools to me represents a true C. bondi. You may be right, but the description of Corydoras bondi contains the following. Head darker than body, with rather indefinite markings. Fins also without definite markings, except that there may be small spots on the central caudal...

This image from PlanetCatfish shows a fish that differs from Corydoras sipaliwini and resembles the fishes from the Venezuelan part of Guayana Highland. Can you expand on your above statement and supply more information regarding location and comparison pictures, to substantiate it. Ian, It is simi...

Ian,
Will you specify where the speculation can be found.

False Corydoras sipaliwini

The image presented by Ian seems to be Corydoras sipaliwini. There are several differences, the most obvious is the long dorsal spine of Corydoras sipaliwini which is somewhat longer than the first soft ray. The false Corydoras sipaliwini has short dorsal spine much shorter than the first soft ray. ...

Only the accepted name at the end of a record is subjective. The former contains too much errors. niede...
