    It's a pleasure to watch these critters swim around. They have the tendencies to swim till near gravels or plants to hunt for food or something, behaves a little like drawf puffers. But they do not seemed interested in flake or palete, maybe not used to them yet.

    Those Hikari micro pellets should do fine. I've a friend feeding them with it.

    Halo!

    Got mine from C328 and they were looking fine in the small tank. However, after putting them in my 2 footer, they turned timid and hide behind the plants. You cannot see them at all. Is it because of my open tank concept. Currently, running 36W PL on a 2 1 1 tank. Feeding them is vexing as I have to pour the sinking tetra flakes into the water and only 2 of them rush out to nibble cautiously before running back to its hideout. Please help!

    Cheers!

    Just Wondering...

    Will all this sudden poaching affect the sustainability of the natural population... since its new and there is a craze...

    Anyways, I bought 10 of these lovelies and have kept them in my Moss tank. Feeding them micro pellets that I bought from Gan's. They love it... all 10 are doing well.

    They are very skittish... fly into cover at any sudden movement... very cute. Seems curious when i stare at them, 1 will slowly come towards the tank to "investigate" then the others will join in.

    Any clearer tips on how to sex these fishes?

    You are discussing their husbandary and this is the correct thread for it.

    They just about eat anything actually. They forage among the plants or near the gravel to pick up food that drops to the bottom. Spend more time watching.

    Don't need to do that. They will need time to get use to your tank when first introduced. Just feed what you normally feed your other fishes, but if you are standing too near, they will not eat in the open.

    Once they get used to the routine, man, they eat like pigs! If you are worried, like I did as some of them were emaciated, then use live food for a couple of days, tubifex, daphnia or BBS to fatten them up.

    Poaching? Uhm, poaching = illegal fishing or hunting. There isn't any law that prohibits this, neither are they endangered species. So no poaching going on.

    Your concern is certainly understandable, but I think we may have reached the saturation point already, and if not, pretty soon, going by the declining prices. I don't think there is any immediate danger as for now as the collection point is not made known yet.

    On the sexing, you haven't gone through the entire thread? There are pictures of male and female each. The pelvic and anal fins of the female is colourless/less colourful.

    Another observation that I made is that the male is normally larger than the female. I am not sure if this is the norm as no one has mentioned this yet, but I observed this from my fishes and also the recent batch in EC, the males are definitely larger.

    Enjoy your fishes. They are really interesting to observe, especially when two males sparring with each other.

    actually in my several batches the females are significantly larger.
    why I don't do garden hybrids and aquarium strains: natural species is a history of Nature, while hybrids are just the whims of Man.

    mine is on tubifex worms, they adapt to changes rather well. But they don't shoal that well.
    Cheers,

    The galaxies are eating now. So far so good. They are not shy or afraid of anyone thought they are the smallest fishes in my tank of cherry barbs, neon and golden tetras and varieties of shrimps. A little "street chase" observed so far between the 2, guessed they are both males.

    Great, do share with us the experience. I will try to get something going myself as soon as I can sort out some things.

    From what I have read elsewhere, it isn't confirmed exactly how they spawn. Some reported successful spawning uses Java moss and/or spawning mops. Cool, alkaline (or close to it) water supposedly triggers the spawning.

    The thread by the same title at Petfrd.com reports a successful spawn, perhaps we can learn from there and compile a list of the parameters...

    There are more than one successful reported spawns. So it's good news. Been meaning to share some of the reported parameters here, but haven't found time yet.

    Lim right? It's actually in the same thread that Ken posted. I am puzzled by the water parameters, which was contrary to what I have read around. I think he shared some more information in there. Will need to re-read and go through them.

    hi all

    ive also been reading the posts on petfrd, from what ive read they are being spawned in a variety of different water parameters.

    the first to breed them are two mates of mine, theirs were bred in soft water conditions i'm also using soft water and getting good results.

    a few europeans are doing them in hard water and still getting the same results.

    i think that anyone wanting to try to breed them decide for yourselves, as they are being bred in both parameters i can't see anyone going wrong.

    cheers

    My galaxies spawned a few times. Saw a few mini galaxies. Minutes later the adult ate the babies. How do I save the babies?

    hi charlessito
    due to the nature and breeding of this fish, a few of us have come up with a reason why the fry come out into open water in the upper regions of the tank, studying the parents they always stay in the lower part of the tank also they keep very close to heavily planted areas, so if the fry stay in the upper region they are fairly safe.
    as to you saving some fry, if you have a nano tank spare set it up and as you see some fry scoop them out and raise them in the nano.

    hope this helps

    cheers
