    So, not to make too confusion in my other thread I thought it would be good to start a new one specifically about IDing my newly purchased ones…

    This was imported as “breviventralis” via Ruinemans in Holland. I find the very close to pictures of SEW04.

    Second one, also from the batch with “breviventralis”. I am not shure what this is. There were only 2 and they were bigger and paler than the others.

    Third from “breviventralis”…seems like SEW03 to me:

    SEW01? Seems there is a bit difference between the specimens (small lines vs. spots). I photographes 3 different ones from different angles.type4-2.JPG

    Sew04 in the first post, Sew02 == Sew03 in the second and third post.

    (Incidentally, “breviventralis” shipments usually have mostly Sew02=03 and few of Sew04…. You want more of 02=03 since they can be bred… 04 so far is unbreedable.)

    In the fourth post: probably Sew01, but do seem just a bit different. The 2nd photo shows a fish with light head — this is almost certainly a disease, bacterial.

    Marmorata seems marmorata.

    Last but not least; I had a tank with the remains of a S. lineolata breeding group that I wanted to stock up…but the new ones are a bit different from theold ones. As these Sewellia clearly isn’t as straight forward to ID as I had hoped, I wanted to include these in the thread to get an opinion…two “typical” specimens of old and new origin:

    Thanks Mike.

    I have 9 of each type if the big pale one I didn’t have an idea about and the third are the same. I emptied the tank in the shop 😉

    Regarding the SEW01 – I will do a “group shot” from above before releasing them into the breeding tank (sometime this week).

    Regarding Sew01: I’d treat the group. Pale head is a bad symptom.

    This is inaccurate but the author is correct that this is serious. and may wipe out the entire group.

    Minocycline may or may not work, but it is a good choice for the first antibiotic to try.

    Monocycline/Tetracycline and other antibiotics are very difficult to get hold of in EU, even if you go to a vet. JBL Furanol 2 is the best I can do (even illegal in Denmark, but have some from before all that was banned). It works for Corydoras which are fairly sensitive, so might be OK for Sewellia too.

    Furan2 is often helpful with hillstreams and seems somewhat similar to Furanol 2. Worth trying.

    Any thoughts on the lineolatas? Just differences within the species?

    Good article you linked BTW!

    Yes, different populations of lineolatas have differences in color.

    Hmm…. actually Sewellia’s are about the easiest hillstream genus to ID 😛

    not really… the author is mistaken that this condition is always a bacterial disease, and also that it is always minocycline-treatable. But no argument that this is a bad sign.

    I agree, Mikev. That’s why in import-stations there is always a diagnosis first.

    @ Kim

    As for the situation in EU:

    is a good choice. Available in EU. Best stuff on the market at the moment. As for all fish with completely/partly lacking scales: tight controlling of the effects.

    Cheers Charles
