    Banggai baby photos coming soon!!...and here they are!

    This little guy is 1 month post hatch. The rest cowered in the corners for this shot. They eat live newly hatched brine shrimp and frozen brine shrimp.

    [​IMG]


    A couple shots of 4 months post hatch. Another month or two and ready for market! They eat whatever will fit into their mouths - flake, crushed adult brine, frozen baby brine, and live baby brine.

    I noticed the pictures of the babies are all in a breeding net did you have to isolate them?

    Also just as an FYI to you and anyone else that comes across this thread :) Banggai have direct development, no larval stage, so technically settlement and hatch happens at the same time. Two reports for the price of one!

    I lost a few to the overflow :mad: so that is why they're all in breeding nets. It is a huge pain to clean those things but I haven't come up with a better solution. Sponges over the overflows get clogged almost daily and cause floods. With frequent feeding a slower return doesn't wash the pollution to the sump to be dealt with. I have the same issue with baby ocellaris, but it's worse because there are 100s of them!

    Have you considered a more porous sponge or filter pad?

    About the only thing that did work was tulle (or whatever you call that stuff you make wedding veils out of) with a silicone band over the bulkhead strainer. That still gets clogged.

    I would use "Cheese Cloth" Its very thin and water would pass through with less clogging *as long as you clean it regularly*...reuseable and cheap.

    I'll give cheese cloth a shot. I'll have to get some this weekend. I also have a space crunch until I sell those gold banded maroons.

    Can't stretch them to much, they will tear. Plus you can layer them to how ever thickness u want.

    Tulle is the same, only with bigger holes. I am just guessing that the cheese cloth result will be the same or worse. Tulle netting clogged the slowest, requiring only weekly maintenance. Regardless, it will be nice once these guys are big enough to not get caught! There is also the matter of a powerhead. It's a 60 tall so I have to have a powerhead. It is perilous to be so tiny.

    Since you are using the Breeding trap have you ever tried to just raise them right in your display? Just curious, You nearly have a system here where you can show that breeding fish doesn't really even require you to setup any new tanks or equipment. That in itself is a pretty interesting motivation to try breeding.

    You could easily raise Banggai's without a separate system. I would never dream of dumping these little guys free swimming in with their parents or clownfish though - they'd be swallowed in one gulp! They seem quite content at this size to live in the breeding nets. It makes feeding them easy. For a time I had them in a 10 gallon with about 200 ocellaris, but the O's got bigger than the banggais and there was a lot of rough-housing going on so it was back to the breeder nets!

    I should take a pic of my new egg tumbler. It works better than the tall shot glass and aqualifter. I built it from this web site

    you could attend wetone's meeting for acrylic works and make a few breeder boxes with flow throughs or replaceable sponges.

    Good idea! I've got a 48" x 24" sheet of clear acrylic, a router, a table saw and weldon. I bet I can build one!

    I bet I could cut a series of very thin slits with my dremel - like a large acclimation box but with much smaller slits!

    I'm gonna get yelled at for inventing another fish project.

    Wohoo! Thanks Matt!

    I thought they should be bigger by now too. I must need to feed them more.

    I moved all my baby banggais to a 20 high tank with tulle over the overflow. I'm going to try to fatten them up. They seem to be growing really slowly. I fixed my nitrate and phosphate problems with vodka dosing and GFO finally. It took FOREVER! Most likely poor water quality was the cause for their slow growth, hopefully it will speed up. Now I have cyano all over my breeding system. Yay. If its not one thing, its another.

    I just moved a batch of 18 newly hatched babies into a breeder net in my DT. Three are not swimming as well as the others so they will likely not make it. My survival rate is increasing as I get better at this and keep water quality high. I am going to attempt to keep these guys in my DT until they are off enriched NHBBS and see if that helps.

    Success count thus far -age based on spawn date:
    167 days old: 1 still runty, eating adult brine w/Selcon
    141 days old: 2 eating adult brine w/Selcon
    116 days old: 1 eating adult brine w/Selcon, cyclopeze and NHBBS
    91 days old: 7 eating cyclopeze and NHBBS
    23 days old: 18 not eating anything yet - still have yolk sacs

    All except the 23 day olds are in a 33 long plumbed to my breeding system.

    Update - another spawn yesterday 10/21 at 2:45 pm!

    The last hatch from 9/13 has 12 survivors doing well.

    Total count of baby banggais = 23!
