Mr. Big continues to do well, and I have some pictures of the broodstock:

Bluestripe Day 26

Here's a picture of Mr. Big, at day 26:

 

 

 
See the yellow fins? I think he's cute!


I've moved him in with some orange ocellaris larvae, as they are eating the same kinds of foods, and they seem to be tolerating each other well, even though the chyrsopterus is 20 times bigger than the ocellaris.  Now I've freed up the BRT for some orchid dottybacks I'm hatching.

I managed to capture the remaining larva and actually get a couple of pictures! He has a fish shape, and long fins, but no definate color yet:




Bluestripe Day 12

He keeps getting bigger, and 2 white dots have appeared on his head, initially, I thought they were just reflections from his eyes, but now I think he'll be a misbar, and I think that he is just past the beginning of metamorphosis!  What do you think?

I'm target feeding him with dry micro pellets, and A panamensis. I'm also hatching brine shrimp, as a last ditch effort to get him through meta as quickly as possible.

Bluestripe Day 9

I've got one brave soul left. He's eating. I've added copepods, Apocyclops panamensis, a couple of times. There is now a sponge filter in the tank, making a circular current, weakly. I've been trying to get him to eat Otoheim A, and I think I saw him strike and eat a particle.  He is fish shaped, but I don't see any stripes yet.

Bluestripe Day 6

Now at day 6, we have one left.  This one is clearly eating and may be close to metamorphosis, as it has taken on the fish shape and some dark color has formed on its body after the tummy.  I've given it a 18 watt fluorescent light during the day, and the blue light at night.  I've started trying to wean it to dry food.  I've added a sponge filter.  Still plenty of rotifers.  After metamorphosis, they are bulletproof, so I am keeping my fingers crossed that metamorphosis happens sooner rather than later.  I won't take pictures, because this one is too precious.

Now at day 7, I've noticed a larvae stuck to the side of the tank, just above the meniscus.  He must have jumped into the tank wall, and got stuck there.  Since it was already dead, it was easy to get a picture under the microscope:


Bluestripe Day 1

The larvae are still swimming energetically, but don't have fat tummies despite an abundance of rotifers.  I guess we'll know in a couple of days if they are eating or not.  I'm feeding the rotifers in the BRT mostly Isochrysis, because a few drops of the new bottle of RGcomplete seems to create an oil slick.  


The larvae seem to really like the blue light, as they are gathered underneath it.


After looking at some of the babies under the microscope, I'm afraid that they aren't eating.  I decided to add some Apocyclops panamensis to their tub.  It's a cyclopoid copepod that is slightly larger than a rotifer, but has copepodites that are smaller.  And they are very nutritious.

Here's a picture of a Day 1 larvae:


Looking at the shiny belly region, perhaps they are eating....time will tell for sure.

Bluestripe clownfish

My friend Kevin has a pair of Amphiprion chrystopterus that he, by magic, got to survive and spawn.  He is a really skilled aquarist! These clownfish don't ship well from the wild, and few survive captivity.  He has them spawning!  He is also a really generous guy and this time, he shared the eggs with me. He scraped them off the rock upon which they were laid, and gave me half.  I hatched them in an upturned, bottom-cut-off soda bottle with air bubbling up from the capped end, now the bottom.  I partially submerged the Hatcher in a partially filled, and heated Black Round Tub (BRT) to keep them warm.  After 2 nights they hatched, and now I am the proud keeper of 50 - 100 day old chrysopterus larvae!

Here is a video of one of the eggs: Note the heartbeat!



Here is a picture of one of the hours-old larvae:


Clownfish Development

Clownfish lay eggs on a solid surface and guard and fan them until they hatch. Nest care is mostly the role of the male clownfish, although the female may take a turn now and then. The picture below is of orange eggs freshly laid on a curved rock surface.

11/18/2010 After many years of raising clownfish in my spare time, I have to say, it is still a fun activity for me. I never tire of seeing the little live swimmers in my tank when they first hatch, seeing their full bellies after their first good meal, watching them learn to hunt rotifers, watching them grow, seeing the first white bands form on their little heads. Will it ever stop being fascinating?

Gotta run now! Gotta go see if the eggs hatched!
