I have never done a side-by-side controlled experiment with this, but I do have a ton of circumstantial evidence!
I have blue tigers as well
After 6 months of regular old EI dosing, I'm selling them off since my fish will eat them but not the Amano's. I had them in with 50 cardinals, 20 cories and EI dosing in a small 20 gal tank packed with plants and ADA AS.
Main thing was feeding them.
I've heard all this same old rubbish in the past about fish and discus and even some species of plants yet through some form of magic and smoke and mirrors I seem to not have issues.............
You need to have a control reference to make any statement about cause and effect and you need to know at least the parameter stated is the cause and not something else. If I add 30ppm a week of NO3, and have no issues over long time frames then I know it's not from the that. I have to look else where for the cause. I cannot say why someone else's shrimp die, only that it cannot be due solely to "high" NO3's.
Circumstantial evidence is no smoking gun............it's speculation and nothing more.............you can guess and pose a possible cause, but if you do not follow up with a test, it's no good to you or anyone else.
It's just an unanswered question.
And we have plenty of those already in the hobby near as I or anyone can tell.
Plenty of folks kill shrimp, have less than stellar results and they do not even keep plants at all or add any ferts of any sort.......same with fish.
Folks can and do gas their fish all the time with CO2.
Then they blame the NO3. Shrimp too, I'd say.
CRS and cherries seem pretty tolerant of CO2 though.
Same for the Blues.......
All I know is that I've kept them, heard these claims and cannot say with any honesty that they are the least bit true near as I can tell. Can I get more brood out of them with lower ferts?
That's simply not the goal.
If that's the goal, to breed.........then you need a bare bottom tank and focus on that.
If the goal is to breed some and have nice looking planted tank, then that is quite another matter.
Now you are trading off not as many brood, but have a nice looking tank.
these are different goals and I agree you will get more brood with a bare bottom tank.
So maybe plants are the problem with getting more from the shrimp here?
Most any breeder will say yes, you will get more brood and larger shrimp/fish etc in bare bottom tanks vs planted.
So that's the other side, but how far are you going with these trade offs and how much is reasonable? Is brood production the only concern?
Go bare bottom then.
If you can handle a little trade off, then you get less brood, but you still get some, and you need not worry about NO3 etc but get a nice planted tank.
You do not get both by adding low NO3. There are way too many other things involved to even come close to saying that that have not been addressed.
This is the part of the research that sucks...........having to go down and rule out each issue one by one to make sure you did not overlook something. I've ruled out several things so far. But I have few issues also......but I'm good at keeping aquariums/feeding critters and have bred many fish over the years. So that's often an advantage.
As far as economics, you can easily make more by having a productive planted tank than you might with a breeding tank given the labor involved and the shipping. Plants grow faster and are easier to raise than fish and shrimp.
Cherries/livebears are pretty easy though. But you tend not to get much for them either.
Still, you might find breeding shrimp more enjoyable than planted tanks, in which case, go non CO2, non planted bare bottom. You will get higher yields since that is something you are suggesting is really important to you.
Try it and start trying to culture some nice high grades and sell them.
Or a monster large shrimp that fish will not eat and that eats all algae.
Now that would be a great breeder project.
I think good sinking sticks are also a big factor with raising shrimp.
I like the spirulinia sticks(not those hikari MSG laden wafers).
The poster "Rain" also does EI and has CRS's without issues, but also admits yield brood with bare bottom tanks, but then that's the goal.
It's not just me
