    Hi all. Thanks for such an interesting site. I have a year ago spawned Sewellia speciosa. Survived only eight fry. Now they are 3 cm and stopped growing. Please say, it is normal that as age sevellia has this size?

    yes and no, Artem.
    it’s normal for tank-bred sewellia that they don’t reach the wild’s caught size.. the reason is simple: not enough food in the first two weeks in the period of hiding (in the field no specimen less than 12 mm are reported for all hillies; but there the fry is swimming in big quantities of food)
    s. speciosa in particular appear when they are about 12mm long. that’s too late to start with sufficient feeding.
    s. lineolata is the species with the smallest tank bred specimen. of my first “series” I have still the smallest – 3-3.5 cm – which spawn now and then.
    it’s better with sew01 spotted, because I feed the adults daily with smallest dry food “Staubfutter” and the normal artemia, frosted stuff, vegetables. this way the fry gets a lot more to eat. they grow up to nearly 7 cm.
    the same effect I had with sew02/03 because the sufficient feeding was intentional for breeding success.
    one more observation: sewellia tend to stop length growth now and then. sew01 spotted start the “large growth” with almost 4 cm, the spotted pattern is completed. my best bred s. lineolata do the same at about the same size; specimen I got hold of at the size of 8-9 mm. they reached about 5 cm up till now.
    that means: a lot of food and waterchanges – up to 50% a week.

    yes and no, Artem.


    Thank you very much. Very interesting.
    Hello. I still have many questions:)
    In Russia sevellia spawn many aquarists: Sewellia lineolata, Sewellia sp. spotted, Sewellia speciosa. But … I do not know a single case of re-spawning. Maybe because sevellia were sold here in large numbers only about three years ago … Now the questions:
    1. Is there some kind of spawning season (in which months sevellia spawn, or they may begin to spawn in any given month)?
    2. Can parents eat eggs or larvae?
    3. It is well known, that sevellia spawn for two or three months. If spawning began in the general aquarium, can I move parents in a special aquarium? It will not stop spawning?

    My guess is that spawning begins at about the start of the year… Why?

    Well I have now advanced fry, about 10mm and another user seems to have fry too! From the loaches.com page it would seem that it taked about 20-30 ish days to get to that size. It seems to be brought on by a cooler than usual water change. I did happen to do one in about early February which may of brought on the spawning.
