My 1st Planted Shrimp Tank

[Robert]

Hi Jack,
blue (which one do you mean? There are said to be at least 3 blue species, perhaps more) and green won't cross-breed. Green shrimps do not cross-breed with any other shrimp in my experience. Cherries do "cross-breed" but only with other subspecies of Neocaridina denticulata. They won't crossbreed with greens. Perhaps with blues if these blues are a subspecies of N. denticulata or a closely related species.

Tiger and diamond shrimps cross-breed easily because they are closely related species of the Caridina serrata group. I don't know yet if bumblebee also cross-breed with tigers but there is the possibilty. I never had hybrids before although I keep bumblebees and tigers in the same tank. But I would be careful. I have just a very small group of bumblebees, so not enough shrimps (and also space at the moment) to give them their own tank yet.

Diamond and Crystal Red "cross-breed" of course because they are the same species and the Crystal Red is only a autosomal recessive mutation of the diamond. So I wooldn't keep them in the same tank if you would like to breed a pure CR population in your tank for a long time.

BTW, it's true that tiger and diamond shrimps are a bit more sensitive than your bee/new bee shrimps. But they do not need a strong water ciruculation if there is enough oxygen in the water. Floating riccia is easy to keep and produces a lot of oxygen, you can see it if there are lots of bubbles. It's a good way to get enough oxygen in a small tank if you use only a spong filter.

best regards

Robert

Robert, You know what I mean. The example I give is just a exaggeration, just to get the point across.

My tiger and new bee always drop the next morning in my planted tank even though I know that the O2 level is more than enough in the day. That's the reason I say that strong water circulation is needed.

Over here, diamond is more hardy then bee shrimp (you call it new bee there). It can be due to wild and bred form, the water parameters play a part or other factors

buy a water test kit and test for metals in the water. Any substantial amount of copper in the water will make the shrimp drop like dead flies.

Looking at Chris' tank, it would be very hard to believe that ammonia or any other product of cycling would have caused the shrimp demise - that is, unless you are deliberately adding this in large amounts to your tank. I say this because the amount of waste two little guppies and a bunch of little shrimp would produce would be *immediately* consumed by the plants. Even if nitrifying bacteria are not present, the plants would consume the ammonia before there is any chance of it being converted to nitrite or nitrate. It would be a different story if it were a sparsely-planted tank with lots of fish. Or could there be a lot of nitrate in your tap water? This would be rare in the U.S., but I think in other countries, it is not out of the question.

Even pH shock is believed to take *days* to "take effect."

We would have to know the tank parameters to make any attempts at guessing, including fertilizers added and the amounts. I agree with jwarper that it looks more like some sort of poisoning. I had a similar thing happen when I introduced both shrimp and a new plant into a tank. I believe the plant leached out some sort of insecticide or natural toxin (it was Lobelia cardinalis 'small form' still mostly in emersed form) and all of the new cherry shrimp and two of my three old Yamatos died one by one in the 2-3 days following. The new platies were okay, though.

Good luck with the new shrimp tank you're setting up. I like to keep my shrimp in "low tech" tanks. Adding fertilizer and CO2 and that sort of thing seems to stress out invertebrates very quickly if the conditions are unstable or too extreme.

You've got the makings of a great planted tank there. The plants look like they are doing very well with the CO2 and lighting levels you have. After your cycle completes, you'll have VERY HAPPY SHRIMP in there. Do you get your shrimp on aquabid? Do you live in the US? Our selection of shrimp in the US is so small; all I can ever find are Amanos, ghost shrimp, and last month I finally found Bamboo Shrimp and got two of them. I would really like to have several kinds of shrimp like you all have but cannot find them cheaply. Maybe I need to give up on finding them "cheap", and just fork out some cash...
