Breeding Amano Shrimp *MODS: Do not move to FW*

Hello,
I've got a number of amano shrimp living in my FW plant tank. Not too long ago I noticed one was carrying a large number of eggs. Since then I have been researching breeding them. It appears that they are very difficult to breed, and few people have succeeded. Desided that I would like to try raising them.

From what I have read, they need to be xfered to full saltwater about 4days after hatching where they need to remain for 40 to 90 days until they look like mini s. Then they need to be xfered back to full fresh water.

Max has already given me a number of tips on setting up and maintaining a small SW tank. However I'm wondering if anyone here has experience attempting this and has some suggested do's and don'ts than might assist me.

Well, I have a ten gallon nano-reef, so I guess I'm qualified.

Some tips I'd give:

Monitor parameters carefully. In a small tank, nitrates, -ites, etc. easily fluctuate.

Water changes, and regular mainenance are very important in smaller tanks, be sure to keep up.

Keep stocking low.

PS: Be sure to keep a log of the breeding attempts! :)

EDIT: I hope you don't mind, I edited the title so a mod doesn't move this thread to FW after seeing the title.

Do do they hatch in fresh water and then move up to marine conditions? What I wonder is how quickly do you increase the salinity I can't imagine you'd want to take any invert directly from fresh water to sea water. I'd imagine that the osmotic shock would be pretty severe. Sort of like dipping a fish in fresh water to treat ich or other external parasites.
Sorry, it's a question instead of an answer but, it might be pretty important to answer it.
good luck

vidiots, I'd suggest going to www.petshrimp.com. There are tons of folks there with breeding experience, and I've seen several threads about breeding Amanos (with their change to SW and everything). I'd suggest searching the forums there before posting, as they will scold you for re-posting something that's already been discussed.
 
Hello,
I don't mind the subject change.

Yes the eggs hatch in FW, because the adults can't survive in SW. The two best sources for infromation I have found so far are:
http://mikes-machine.mine.nu/breeding_yamato.htm
http://caridina.japonica.online.fr/English/Elevage.htm
According to them the shrimp are hatched in FW then washed down stream into the ocean, where they go thru a series of molts then swim back upstream to FW.

I moved the egg carrying female to a small isolation container of FW last weekend. The eggs hatched early morning Thur Oct 26, 2006. This is my first batch of eggs. My SW tank is not fully cycled yet, because it too was just started last weekend. If I had to guess I'd say that atleast 300 eggs hatched. I moved the adult female back to the main aquarium this morning.

Since I am not completely prepared for this first batch, I don't hold out much hope for them, but there should be another batch in a month or two. As for duration in FW hatching container one source says no more than 8 days, and the other says atleast 3 or 4 days. I think I am gonna try to move them to the SW tank anyway, figuring at worst if they don't survive they will hopefully cycle the tank for the next batch.

According to both sources they do not suffer from the shock of going directly from full FW to full SW. This just seems counter to anything I know about aquariums. I figure since I have so many hatchlings, I can try both rapid and slow change and see which has a higher survival rate.

I find it really hard to believe that they don't suffer from osmotic shock. There aren't any river systems in the world that go from pure fresh water to sea water it just doesn't happen,"as you know." I'd be curious if that might be part of the reason that some of those folks had limited success? Anyway it might be worth at least a drip acclimation on one batch just to see if it makes any difference.

If they are going to die anyway it shouldn't hurt anything to add them to the s.w. tank. Please, keep us posted when they get ready we'll move this back to f.w. for you.
hth and keep us in the loop. If you don't mind and it meets criteria we might make this an article?
