  1. Thought I'd come back and update this thread.  I was doing some maintenance today and moved a piece of wood and spotted two baby shrimp.  maybe the size of a rice grain and fully deep blue.  I never noticed them before because they're about the length or a bit shorted than my gravel and my gravel is multicolored (natural) so they blend in.  "the internet" says it takes about 2 weeks to get color in babies so if they're two weeks old it aligns with the day I noticed the eggs "getting dropped".  All this is incredibly tight timing, I added males on the 27th of feb and got hatched babies 3 weeks later.  That or I had a male and didn't know.  3 week hatch time is pretty fast from what I've read so maybe my water is hotter than I think it is. my thermometer/thermostat says 24C, but my cooking thermometer says 78F (25.5C), so now I'm inclined to believe my cooking thermometer. 

     

    In retrospect I hope I didn't gravel vac any, but I've mostly been vac'ing open areas.  In any case I'm thrilled about the 4-6 I spotted after looking around some more and who knows how many are hiding.  Could be 50 more 😉 (the mom was BIG)

  2. I hatch about 1/2 g (1 scoop is usually 1g if it came with a little spoon) and feed the same day (as hatched) then freeze the rest into tiny ice cubes.  Mostly because I'm only feeding <20 nano fish so it doesn't make sense to go through the effort more than a 1-2 times a week.  I feel this is the optimal balance of nutrition and effort for me.

     

    and honestly if i didn't find feeding bbs fun I'd probably just stick to pellets and flake.

    I've just been over the moon after finding out I was getting a C.A.R.E. package. I really have no one to talk to about my tanks or aquatic critters, and I'm just so happy to be a part of this forum and wonderful community. Thank you very much for the package; my little brain meats are working on a possible new project using some of the items... if I can find a spot for another little tank!

    Cory said he won't ship fish but he'll ship a dog?!

  4. AH! so they are cannibals then!  They are vicious at feeding time.  its a good thing they're competing with guppies and not a slower fish.

     

    They all seem so happy and healthy color is good. 

     

    Internet says an average cardinal tetra weighs 130mg, so that's probably only 5-10 feedings worth, so I may not even notice the extra nitrogen released if they get digested and broken down slow enough.

  5. I had water lettuce with the first batch that I moved over.  I guess I should have said I didn't have any plants that I thought would be good to lay in.

     

    If I transfer all my extra water lettuce I have to that tank in there is that enough to protect fry until they're big enough to spot?  How can I be sure they're fed until then? right now I'm feeding the parents BBS and flakes.

  6. I've got 7rice fish and one of them is making 3ish eggs a day.  when this started looked up what to do and threw in a mop because there wasn't any plants (this is a temporary tank until it warms up outside).  After 10 days i inspected the mop and found 0 eggs but threw it in a tub with an airstone just incase.  I also made a second mop and put that in with the fish.  It's been 12 more days and no hatches, and I don't see any eggs in the new mop either.  I'm assuming she's dropping them on the substrate but they'd be impossible to spot there because of the mixed color gravel. 

    Are there other mop designs or some other way i could go about this?

  7. Thanks guys! I knew I was missing something!

    Found something! From an EPas pamphlet:

    https://www3.epa.gov/npdes/pubs/dechlorination.pdf

    So any extra SO3/sulfite (or S2O3/thiosulfite I presume) can react with oxygen to form SO4/sulfate. 

    So does this mean once we open our Prime bottle or whatever we use that it will eventually go bad because of atmospheric O2?  I wonder if there's a preservative that reacts to the O2 first and makes oxygen depletion in the tank worse.

  8. I'm same city waiting to get plants too.  my plan is to go easy with water hyacinth and some kinda lilly.

    I'm throwing in medaka as soon as I feel it's warm enough not to shock them.  I'm watching this thread close for more ideas👀

    EZ Carbon won't hurt shrimp or eggs. But, shrimp love algae, unless it's completely out of hand I'd leave it. I wish I could get some algae growing in my shrimp tank. I'm pretty sure they did better with it,  but it cleared up on it's own and I can't get more growing no matter how long I leave the lights on.

    shoot that's a good point.  They don't seem to eat the hair algae, or at least they don't eat enough, but there's more than that in there.

     

    Hmm maybe i can "rent" an amano shrimp.

  10. My monte carlo has finally begun to adapt after probably a month or more and I'm seeing some clusters of new growth but all around it and on it I have a hazy layer of green hair algae that's pearling 😠 .  The non-carpet zones I've been able to gravel vac and the tumbling has kept different sides of the substrate exposed to light so the green hair is less bad there.  At times I've even picked at my substrate removing one pebble at a time with tweezers and replacing it with a fresh pebble from the bag, but it turns out that's not a sustainable strategy.

    I'd like to give my MC a leg up so it can really get the light it needs, so I'm considering an algaeside like easy carbon.  I've mentioned in other posts that I had my first berried shrimp drop her eggs and was bummed out about it, so now I'm extra paranoid.  Would easy carbon hurt my shrimp's eggs or their desire to carry them?

     

  11. Heh.  Thanks guys.  I lost (she dropped) my first shrimp eggs, but I'm sure I'll get babies eventually to replenish the numbers.  In theory I still have a dozen or so.

     

    I was just wondering if there was anything I could have done better. Gh is 6-7 not sure how much of that is calcium in worried about molting.  What's the name of that calcium+spirulina shrimp food block?  Can it hurt to add one of those?

  12. Why does dechlorinator lower oxygen in a tank?  I've heard this a lot and I don't get why.  I tried to look up the reaction between sodium thiosulfate and chlorine and I found two reactions depending on if its cl2 or chlorite:

    Na2S2O3 + Cl2 + H2O → S + 2HCl + Na2SO4
    Na2S2O3 + 4HOCl + H2O -----> 2NaHSO4 + 4HCl

    Neither of these seem to consume any O2.  Is there an downstream reaction with one of the products?
