Amano Shrimp Larvae Growth Progress - Updated

If you have ever wondered how the larva hatches...

 

Wow that's brilliant

how long have you been breeding amano ?

 

Not long, just recently had my first successful batch of 20 that are growing out and still smaller than Cherry shrimp.

My last batch of 100+ all died due to my mistake of cleaning up the algae, I guess it suffocated them the next morning. I was doing this for the last 5 years on and off, mainly off but going to continue now that I have a better understanding even with some set backs.

The current batch is even larger since it's about 5-6 females that gave birth. I've been collecting a lot of larvae every day that I thought about stopping since I never ever raised this amount. Definitely a challenge for me when it comes to the final morph phase in catching them all.

 

I lik it keep us updated and think about letting us know what the breeding program consisted of.

 

I agree, I'd definitely be interested in seeing more of this!

 

Very cool and good work!

 

Thanks, I'm really a novice with this and have no repeatable results yet to be comfortable for someone to follow and plus i'm experimenting with additional feed that the guide doesn't do. Not to re-invent the process, this guy's guide is what I followed. My only advice to set up the grow out tank following his direction to grow algae and when you see a decent amount of algae on the glass then it's ready. Most fail because they starve I believe.

Here's a video I took today, I stacked both extension tubes and got an even closer magnification. You can see them eating the crushed flakes.

 

Well mach6 that is unbelievable and the second video is awesome, ive read on forums over the years of people claiming to have bred Ammano but none of them showed videos or pics for that matter when I've asked, you are the first who as done so, I am totally speechless, there is another on Fishlore who is trying and failed the first attempt but have heard nothing of his latest attempt,
I'll follow your progress with interest
Well done

 

Fantastic video.

 

I was surprised by this I captured yesterday, they hatch slowly too... I guess he's not an earlier riser.

It stretches at 1:30 and starts to come out at the 2:18 mark but it's interesting to see what happens inside the egg before that.

If you're wondering what's all the green and brown stuff, that's Amano shrimp poop up close. Also the bugs swimming around was from a local pond I was raising for fish fry in their tanks.

I think some morphed or became more red from the algae.

The light is from below this time, you can see more details to their shape.

At 1:45, I slowed it down so you can see them a bit better from their twitchy movements.

 

They are coming on great. How long dose it take from born to morphed?

It's hard to say, I'd think it's more dependent on each on how much they eat more so than a time thing. I just noticed some coloration and their bodies are a bit elongated.

Because my batch here has some larvae collected more than 7 days ago, it's almost impossible to figure out when they will morph. I believe they have at least 3 stages of larvae growth. Next time I'll try to do a controlled group to grow out.

 

Normally I don't care youtubes blocked in china but now I've go to find a new free vpn since my old ones not working to watch this.

 

These shrimps larvae were visibly different and looks larger and more red. I believe there are still 2-3 more morphs until it's turns to a shrimp. At this point, they're able to grab and eat floating foods and less attracted to the light.

 

wow that's amazing! keep posting!

 

I cleaned out the tank entirely to scrape some algae and remove any dead larvae. I found some that was still alive and not moving until I had a closer look. This is just laid there and ate for the 20 minutes I recorded it. Found another bit of an extension tube to give me just a bit more magnification.

 

The mother shrimp expelled her eggs. They look like they're too early to hatch but you can see their internal organs moving.

 

You really have an ammano kingdom going there

 

Yeah, you need a lot, I don't have a good survival rate. It is probably 40% if that of what I had originally collected out of a few hundreds. Not sure why some die, I guess survival of the fittest!

 

I think we are almost there... They usually get a lot of those legs then next or next 2 morphs and they should have their swimmerettes to be able to swim forward.

You can it has a lot of those little legs and it can actually swim with them.

 

That's brilliant like a how many have made it to that stage

Can't really tell, at this stage they don't really move around and just stay still and eat. I would think the survival rate might be another 20~30 like last batch. I think next batch I will clean out this tank and re-grow the algae. Too much of the green algae grew which isn't what I wanted. You want the brown diatom algae which is only growing on the top half of tank. I will reposition the lights so they are not so close and intense.

 

In some disappointing news, I'm down to like 3 of them with a darker red color, hopefully they will survive. I put in 20 newly hatched ones. Not sure how or where they are disappearing too since I don't see too many dead. Oh well, there's always the next batch. I definitely needs to scrub the entire tank clean and re-grow the algae.

 

Really fantastic quality videos, I've never seen someone post anything close to this before. Are you using a microscope?
One thing I've always been curious about is the possibility of selective breeding amanos to be certain colors, like cherry shrimp have been, but of course their difficulty in breeding hasn't made it feasible for the hobby yet

 

Do you think its possible to selective breed colours fascinating if it could be done

Do you think the young eat the dead if there's no bodies

 

I use a Nikon D610 DSLR, I stacked on extension tubes and reverse mount a 24mm wide angle lens. I used this for my bug photography but didn't think it would work but I guess it was bright enough. I just got some more extension tubes so I wonder how much more closer, if any I can get. The extension tube set up with lens is over 1' long right now.

Unfortunately, these shrimps don't vary color much unless you probably inbreed but I don't want to do that. About the only thing I'll try to selective breed for is the size.

I've been wanting to try other low order shrimps like bamboo and green lace shrimp but I'll hold off for now.

 

Here's a new video with the extension tubes. I put these into the grow out tank but not sure if I will go through to the end with it since I want to start fresh with the algae.

 

Like little tap dancers another brilliant video could you post us a pic of the video setup

 

This is the camera set up. I put the subjects into a small container on top of one of the low powered LED lights from one of the small 1~ G tank kit for the back lighting.

Since I already had extensions tube about 3/4 of the total length, I figured I'd just invest in another set instead of buying a microscope for my phone or PC.

 

OK that's a little bigger than I imagined

 

This is the one I wanted to record last time but lost track of it in the water. It looks like this is should be on the last morph before I start the transition. You can tell because the swimmerettes are almost developed and has even more arms. The green inside is likely the algae they eat.

Let's hope this little guy makes it, the other one is behind in development by a one or 2 phases.

 

It's remarkable what these guys go through just for us to put them in a tank and look at them.
How long as it taken to get to that stage?

 

I usually vacation somewhere where I can snorkel and some areas are very rough, it makes you wonder how these little guys can survive an unforgiving ocean and make it back upstream into freshwater. What we set up to grow them out is like vacation for them. The only thing they have to watch out for some times is bubbles.

It's hard to say since I wasn't able to keep them under a control environment from the beginning to only observe a select few. I think most literature say it takes about 30~60 days to morph. I'd say this has to be just about 20~25 days?

 

I'm actually really glad I came across this, It gives me confidence to try this myself. I have had the 2 female Amano shrimp in my 10 gallon berry at least twice in a year but never took it beyond that. You make it seem so much less daunting. Thanks for the post and the information, keep up the great work!

 

That's great, give it a try. It's minimal investment. You can buy the cheapest salt but don't get Red SEa, it leaves a residue and takes a while to clear up. I may have to hold off since it's been getting too cold in my basement w/o using a heater. I'm trying to do it low tech w/o using a heater but I may get another betta heater from Petsmart since it seems to have passed the reliability test of keeping it at 78 in my 1.5G S/W nano. That's probably why it grew much faster during the summer.

 

I think I'll wait until the next time I see fresh eggs so I have a better idea of the age and where she's at in the process. I'm sure they'll berry again no doubt but I'm also trying to get at least 2 more females to make 4 total in hopes of bettering my odds. I'm also setting up a new 3 gallon shrimp tank fro some RCS to try my hand at them too. The shrimp hobby really hooked me hard like I never imagined.

 

Well sinned4g63 I've watched this thread with great interest and could not match the knolageae of mach6 but I can give you all you need when your ready to setup cherries

 

I had lost a lot of eggs from putting the females separately in containers, I am not sure how others keep them in there w/o filtration with the shrimp or the eggs not developing fungus. I had changed the water frequently but still lost many eggs from fungus developing on the eggs or on the shrimp itself. Once I used a filter, it helped maintained water quality to be able to hatch and collect.

I never got into the RCS, I had some chocolate or blueberry for a short while until they were eaten by my Amanos. Plus I consider them too small for me. I was looking to pick more shrimps like bamboo or if I can get the green lace shrimps.

Ahh I bought the Amanos to help with algae and just fell in love with them. Knowing the difficulty in breeding them is what sparked my interest in RCS. I had a Betta in a 1.6g that died and decided it would be a nice possibility but ended up feeling like it would be too small and cramped for what I'd like to see happen. Honestly I've grown to like shrimp just ever so slightly more than fish being that my main interest was initially Bettas which I would ultimately like to breed as well. Between the Shrimp and Bettas the hobby is quite consuming as it is.

 

Yeah, these guys grown on me also because they live long and active. Ghost shrimps are alright but they don't live long, Whisker are fun to watch and active but they didn't last long either.

Unfortunately I don't think this larvae may make it. It has got to be the laziest larvae I've ever seen that just lays there and barely moving. I'm not sure if it's the water temp being colder or the water itself. I better start prepping a new tank to grow out the algae.
