One of the members of my planted tank club (http://www.njagc.net/) is attempting to breed them.. however the forum is private. I'll post some relevant quotes from the thread:

I have tried this unsuccessfully a few times, but alas, at the current time, this is the furthest I have ever gone.

I am on the 26th day and have a handful still left in saltwater.

My journal on this is very spotty and honestly, the success to date was a bit of luck. One of the PC bulbs I had on the tank burnt out during the second week (figures) and I think this was the cause of alot of the die off I had.

If I had to say how many I still have left, perhaps a dozen or less. Some bigger then others.

The next step seems like the hardest of them all, determining when they metamorphose the first time, which is the critical point at which they would begin their return to freshwater in nature.

Going to give it a shot and pick and choose one or two here and there and see if I can decipher the appropriate point to remove them.

Fortunately, I have two more berried amanos in the wings standing by to release their Zoe's, so I will be doing this again very shortly (with hopefully better results).

I can say that I was not fully prepared for the first batch, which may have also contributed to the massive die off. The salt water tank had only been running for a day or so and the algae culture was not fully developed yet, but I really didn't start seeing the major die off until that bulb went out.

Will try and keep this updated as I learn more.

Kind of fun though!

I was able to siphon out 7 yesterday. I think there are a few more in there, but I just can't find them. They are so tiny.

So, they went into a small glass with straight salt water and stayed overnight.

This morning I changed 50% of the water with freshwater. They were not happy to say the least, alot of jumping around.

We shall see if they survive the day. If so, I will do another 50% each day for the next few days until they are in a full dilluted freshwater. Then into the 1 gallon they go with some moss and pelia.

On a side note, I have the other two berried amanos on stand by and I am just waiting on them now to let those eggs loose.


I will take a picture tonight of the little glass I have. Even if they don't survive, you can at least see how tiny they are.

Down to two. One is not looking good and still swimming upside doen which means it may not have gone through its metamorphosis properly.

However, the other one is a winner. Swimming head first and digging into the moss I put in there.

There is much to be learned about the transition to FW and I have alot of testing to do the next go around.

Here is my first hypothesis which I want to break down on the next batch:

First and foremost, the surface tension is a major issue. It appears that once FW is initiated to the SW, the specific gravity obviously changes and I think the juvenilles have trouble with buoyancy (which makes sense). So, they tend to float toward the surface. Too much suface agitation just kicks their butts, so I need to create a fine turbulance at the top, just enough to break the tension, but not shoot them all over the place.

Second. Bigger container!! The cups are just silly. No need. Maybe a 2.5 gallon next time.

Third. Drip acclimate slowly. I am going to set it up with perhaps about 1 gallon of SW from the initial harvesting, then have 1 gallon of FW in a jug and have it set up to just drip in really really slow. Once its done, do it again and again til the SW is almost fully dilluted.

Fourth. Do not extract the juvenilles until full molt has occured. From the reading I have done and what I have witnessed so far, they need the SW to get through the first molt. It was clear that once FW was added, the ones who did not fully molt where goners. (This may also tie into the bouyancy theory since the exoskeleton may get more dense after the first molt, which may help them control their movement as the specific gravity begins to change).


I tried taking pictures of the little guys, but you can't see a damn thing. I need to get a better lense for my camera.

Hopefully if anyone from that forum sees this, they won't get too upset about the copy and paste job.
