Am I doing something wrong? Help

    I have 11 beautiful blue platy fry. They were born May 23, 2009. They are almost a year old now.. and they are all still about 1/2 the size of an adult! I change the water regularly, every week or every two weeks and I feed them twice a day. I have heard that they grow slowly, but I thought by a year, I would have at least been able to tell their gender, but they are still too small for that.
    So what am I doing wrong?

    Thank you. :)
    I have Neon Tetras and some Oto algae-eaters.

    Just checked them:
    A: 0
    Ni: 0
    Na: Between 0 - 5, but closer to 0

    Mine seem to grow much quicker than that. Mine got to half an inch in about 4-5 months and close to adult size at around 7-8 month.

    How long did you keep the fry seperated from the other fish? Also, what have you been feeding them?

    I had them in a breeder tank until they got big enough that I felt they would be safe with the adults. (I don't have a second tank to keep them in.. I only have one). When I put the first two biggest ones in with the adult fish, they chased them for about a minute, then everything was fine. They got along great. So once the other babies got to be about that same size, I put them in with the adults. Now they're all together and seem happy.

    I fed them baby bites for the first several months, but now I have switched to Tetra Color flakes.

    Are they able to compete with the others for food?

    No, not at all. They are all eating fine.

    Hmm... I don't know what it could be then. I feed mine a pretty varied diet which included egg yolk and first bites fry food when they were really little and then later on, I fed crushed flakes, micro work, cut up blood worms, baby brine shrimp. I just really tried to mix it up. I don't know if this contributed to their growth or not.

    I guess if they are healthy, that's what is important.

    How long were they in the breeder box for? Possibly they got stunted by being in a small space?

    Um, about 2 or 3 months cuz I wasn't sure. After I put them in with the adults, they grew a lot more but now they are really really growing slowly.. so slow that I can't tell they are growing at all.

    I'm still pretty concerned about my little ones. If anyone has any suggestions of what I could do to encourage growth, I would very much appreciate it! :-\

    They may have been stunted from being in the breeder box for so long. As long as they are eating and seem happy and healthy that;s all you can hope for. If they are going to grow more making sure the water stays as clean as possible will help.

    I would try baby brine shrimp, its supposed to help with growth in fry but if they are a year old I don't know if that can be changed.

    Just an update... the babies will a year old in a few days, but they have finally reached maturity! I can now definitely tell their gender now. I noticed this for sure about two days ago. They are still very small, but they do seem to be getting darker in color and growing just a tiny bit. I guess they do just take a LONG LONG time to grow.

    Hi JCgirl. When Livebearers are kept together and allowed to breed, the older fish release a hormone (possibly in their urine), which slows the growth of the younger fish, this is to slow the competition for breeding rites. When raising the fry, I find that doing waterchanges every 2 days increases growth rate by about double, as it dilutes the hormone.
