I have had three Tiger shrimps (one male and two females). Both femails have laid eggs, one of them hatched 3 days ago and now she had just laid a fresh batch of eggs today!!! Amazing because it was only 3 days after her previous eggs hatched and now she is carrying eggs again!

I think it must be the Indian Almond leaf (Ketapang Leaf) that I add into the tank. It is suppose to be a magic leaf for inducing breeding in fish but it seems that it also induces shrimp breeding too!!! Now I believe why they called it magic leaf!

More information of Indian Almond leaf could be found here:

Here is one of my pregnant Tiger shrimp:

This may perhaps be true, but take into consideration that there are other factors that must contribute to the process. Egg production is a continuous process and is highly dependent on nutrition. While the shrimp is carrying one clutch of eggs, it is already developing more eggs. The amount of eggs it produces during the descended-egg (those among the swimmerettes) incubation period is dependent on how much food is available. The less food there is, the fewer eggs there are. In their natural habitats, I would guess that a new clutch of eggs within three days of a hatch is not unusual. In suboptimal conditions, it can be weeks between clutches. I honestly dont' know how much the almond leaves help and would guess that you provided water that your shrimp simply LOVE. Congrats!

Your explanations make sense to me. Perhaps the Almond leaves provides the ideal water condition that they like hence the non-stop breeding!?

Hi,
I tested the Indian Almond tree leaves (in Singapore known as "ketapang", in German known as "Seemandelbaumblätter") several times with several species e.g. tigers, CRS, cherries, green shrimp etc. . Most of them didn't care, some like the CRS even disliked them. Their colors faded drastically. All in all I saw no advantage of these leaves at all.

regards
Robert

I use oak leaves instead. In Germany we have no Almond trees so these leaves are too expensive.
I just use leaves because shrimps and crays eat it.

They must love the Indian Almond leaves (http://www.theteh.com/html/indian_almond_ketapang_leaf.html) indeed!!!

Ooh err! I will pick some leaves today, I suppose dry leaves are better or slightly older dry leaves from under the litter? I must say where the wild shrimp live here in the densely forested mountain streams they get a constant supply of leaves i.e. there is always a layer of leaves on the bottom.These are assorted species, all semi deciduous broad leafed trees. So I think oak should be fine elsewhere. Though the leaf/causal water quality I think is not so important. As these streams are constantly running with fresh water from mountain mist and seep or heavy heavy rain as today, and as these streams are close to the water source i.e. high up in the mountains the leaves wont have time to leach much back into the water though in winter this is different as the water hardly flows. Our black rain storm warning has been hoisted. I can't get into the garden for awhile.

Late spring seems the time the blue shrimp go mad dropping eggs. There are now always a constant peppering of pregnant females lying ontop of partly submerged water lily pads scattering their eggs. The temp has gone from a steady 23 to 26+ recently, maybea the switch or the heavy heavy rain?

I think when using IAL we have to remove all the tannins by soaking the leaves to leech it out or you can boil the leaves (what some betta enthusiasts do to remove the tannins). Not all shrimps prefer acidic water since IAL will drop your PH if the tannins are leeched. By the way, does anyone know how much the IAL will drop the PH?

There has been a discussion on this topic in another forum that there are different subspecies of IA trees and hence the degree of tannins within the leaves depends on the species. My IAL came from Malaysia and has a different leaf shape to those available for sale on ebay from Singapore.

Those that I use definately did not leach much tannins nor they reduce my water pH!

I didn't know there were different varieties of IAL, very interesting. I bought my leaves 3 for $1 at my LFS and they leech tannins pretty well. There are some fake sellers out there who will sell you used leaves; that is, leaves that doesn't leech any tannins and has been used once already.

I don't think I have bought used leaves as these were from a trusted source (a friend of mine). One can tell if the leaves have been previously soaked in water or not. The Malaysian IAL has a round oval shave leaf compared to those from Singapre.

Compare the two following leaves from
Malaysian:

Small tiger shrimps look cute.

I also use almond leaves for my CRS, but I don't have good result yet.

Maybe they need to grow more.

Hi

I have tried to breed tiger before but have never succeed. Can you advise your water parameters like the PH, KH and water temperature?
