    Hopefully this will be interesting for you.

    I’ve obtained some loach eggs yesterday (again, pseudogastromyzon/vanmanenia tank, no certainly whose)… these;

    the eggs are huge (2mm) and most are rapidly developing. Actually some are moving around now…. whether they hatched or not depends on the exact definition of hatch… this larvae is strange.

    I’ll try to document the process on this thread; this is as not to repeat the same posts in several places. I’ll try not to kill them, of course, but this is the first time I’m artificially hatching loaches….so apologies in advance if something happens.

    Very cool Mike! Will be interesting to follow their progress.

    Aliens! What are you shooting with Mike??

    PS. if you haven’t followed the link to “this thread”‘ It’s definitely worth a look!

    Very nice documentation and amazing fry photos Mike! By the series of pics you posted in the other thread do you think you might have recovered freshly-hatched fry with yolk sac attached rather than eggs? Only asking as there appears to be no sign of eggs hatching in your pics?

    What do you intend to feed them once the sacs have been completely absorbed?

    In answer to the question you’ve been asking, some people would refer to the young as fry, others larvae. Personally prefer the former but think both are correct.

    Thanks, Matt,

    I definitely collected eggs. The way they develop it is very hard to notice hatching: they first release the tails, then the shape of the yolk sac changes, and the egg shell gets shed sometime along the way.

    I realized that I don’t know what the term “hatching” means anymore… if you define it as shedding the shell, then some of the fry hatched 2-3 days ago, and only yesterday night, but they are equally developed and mobile…. does not make sense. If you define “hatching” as piercing of the egg shell, well they all did it three days ago when they grew the tails, but they had no mobility at the beginning.

    Food: I was asking for good ideas. In theory, they should eat everything, they are fairly large and omnivore scavengers….

    I’d define ‘hatching’ as the overall process of leaving the egg and ‘hatched’ the state of the fry post-hatching i.e. once they’re 100% independent of the egg.

    If you want to feed them live stuff microworm might be a good choice as it tends to sink.

    With this definition, hatching took 3 days, they were shedding the shell at different times…but this had nothing to do with the development. (Reason I’ve been asking to make sure that if this leads to a write up I use the term correctly…maybe I should just avoid it, safer this way .)

    Hmm….microworms….let me try to get them to, thanks.
    I’ve been thinking of sinking some powdered food (Sera Micron), algae on a plant, and killing some artemia for them (I’ll give them some live ones, but doubt they can catch them.). The older fry in the tank ignores algae wafers that the adults eat but is interested in small flakes.

    At the current rate, the yolk sac should be used up by Thu +- a day.

    Here is a new shot of their possible older sibling (shown before on the S.elongata thread):

    I’m surprised to see some color already, most of the adults I got at 1″+ with no color yet, this fry is 0.5″ and less than 2 weeks old… This does not help with figuring the species, the same yellow appears in both species.

    Really seems to be growing fast Mike, looking good!

    Thanks, Jim,

    They are getting braver too… I see them out during the hour of madness…11-12pm, during and after dinner, is the time when the ladies beat up the guys and the lizards… the fry used to hide, now they watch.
