    Here are some photos of the tank from today.  A new air pump for the hamburg filter wall is on its way, should be here tomorrow.  After that I plan to remove the airstone, and no equipment will be visible inside the tank.

    Hopefully the plant roots will grow along the wall and cover the foam.  When I move in a few weeks, I also plan to cover it with sand again before putting it back together. :)

    Yes, I will definitely have green water and infusoria in with them.

    I wonder, did the oyster relish have enough unsaturated fatty acids?  Apparently that’s a big thing with these fry, and something most of them spawned in captivity miss out on in their diet.

    I hope to be able to find a specific gravity reading on the areas the fry are found in at the estuaries.  It may be that salinity is as big an issue as food.

    Oh my gosh guys, thanks so much!  So excited to hear from people who have actually been there and done that!

    I did end up getting B. hulstaerti (good my research proved correct).   However, a friend who’s bred ansorgii advised not to put them in the tank.  Because my intent is to breed the ansorgii, I don’t want to put the (very expensive) B. hulstaerti at risk of getting attacked for eating the occasional fry.  So they are going in their own tank LOL.

    I wish we could “like” posts here.  Everyone would be getting thumbs up!

    They are very easy to spawn and you get thousands of eggs every few days. I tried lots of ways of raising the fry. Different water depths, temperatures, filtration, salinity and all types of foods – green water, rotifers, mud from rock pools etc. etc.
    The best I did was 10 days.Hypseleotris_compressa_spawn.jpg

    Oh wow.  Never in my wildest dreams did I think you’d ever see this, Graham.  I didn’t even know you were a member here.  LOL!

    Do you know the micron size of the foods you were trying?  I was reading about your methods last night (earlier today for you Brits :P) looking for inspiration on things to try.  I came across a product called Troch-feed (oyster larvae initial stage) that are cryopreserved and probably very expensive and hard to find.  But apparently this is one of the feeds the gudgeon larvae would have in the wild, they also swim around the same way as the gudgeon larvae.  The ones I found are size 50 microns.  Reading up on someone who is working on captive breeding in Australia, he suggests a first food size 10-20 micron and smaller and apparently has a method for culturing these foods.  Hopefully he will contact me with instructions on how to do this, as I’ve never tried raising such small ciliates before.  My hope is that the ciliates from this culture will be able to sustain the fry until they’re able to accept larger food.  If it doesn’t work, all I’ve lost is time.  I already have the gudgeons and most of the equipment necessary to do this.

    I also wonder, Graham, how you transitioned the larvae to brackish water, and the approximate gravity you kept them at?

    I wonder if there is a way to find out the specific gravity of the estuaries where they’re found in the wild.

    Looking forward to it! What are your water parameters for this aquarium?

    I couldn’t tell you exact numbers.  Even if I still tested the water, my dogs ate the color chart for my test kit LOL.

    However, I do know that TDS is in the middle range, somewhere between 50-80 depending on how much water is in the tank and when my last water change was.  gH and kH both very low, kH is likely negligible.  My test kits for those two have never once given me accurate readings, because the numbers are so low.  pH is lower than 6, sometimes ranging down around 5.2-5.0, depending on how recently I’ve done what I call “re-blackwatering” aka adding homemade tannin water to the RO water for water changes,  adding IAL, and sometimes “betta spa” if I haven’t had time to make blackwater extract.  

    I haven’t done nitrogen testing since the first month I had the tank set up.  So many plants, I figure there is no way there’s ever going to be a reading for ammonia, nitrite, nitrate ;)

    When I re-do the tank, when I move, I will be keeping better track of the water.  My boyfriend wants to build a computerized fishroom with sensors detecting ammonia, nitrite, temp, pH, TDS, and probably some other stuff I’m forgetting.  It’ll be set up to send readings to my smartphone or tablet, so I’ll know exactly what’s going on in every tank at all times, eventually, when we get it built. :)

    Nice! Are the ones in the pictures wild, or are they some you bred yourself?

    They are the parents of my babies :)  I got them from Hermanus Haryanto.  I don’t think they’re wild caught, but true wild strain as he keeps impeccable records and keeps all of his strains separate.  If I remember correctly, the male of this pair is F3 from wild caught.  Not sure about the female.  His fish are prolific spawners, so I’m sure she’s a lot further down the line, if you know what I mean.

    I do have two pairs of wild caught coccina complex fish, but I need to fix up their tanks before I dare show them to the public o.o  They need a LOT of work.  LOL.
