I'd say you're right.

Hi Alison
Nice find! What size are they? I'd say no to

Trachelyichthys exilis

based on markings, but I'm definitely no expert.
[EDIT]
Looks like Siluris beat me to it, so I bow to his identification skills.

Thanks.
I have been meaning to get a picture of them for months. I think they are 3 inches max. Typical woodcat -fleeting glimpses here and there.

Based on the positioning of the eyes I agree with T. exilis, although the colour pattern of your fishes seems a bit a-typical (no spots at all?).
T. decaradiatus was named after its ventral fins having 10 rays (each), but T. exilis has that too....
When the eyes are positioned almost on the nose, you have exilis; when a little backwards on the head you have decaradiatus.
According to Greenfield & Glodek (authors of T. exilis) the differences are not hard to see. One tiny problem: one should have both species to make a comparison
