My clownfish started laying eggs agian for the first time in 2.5 years and I decided to keep a log of their laying activity and the growth of the offspring.
Species: Black & White Ocellaris Clownfish (Amphiprion ocellaris var.)
Background: I purchased this pair of clowns in December of 2011. This pair had been laying eggs consistently before I purchased them. I have no idea how old they are, I'm guessing that they are about 4-5 yrs old, but I have no real data to back that up. After purchasing the clowns, they quit laying eggs. I attribute this behavior to lack of proper nutrition, as I was only feeding them once per day. In March of 2014, I purchased the AFS module for my Apex Tank Controller and set it to feed twice a day (at 11am and 5pm). Spawning behavior started in late April.
Since I'm starting this a little late, I'm going to back log some things.
21 April 2014 - Spawn 1 laid
30 April 2014 - Estimated Spawn 1 hatch.
7 May 2014 - Spawn 2 laid
17 May 2014 - Spawn 2 hatch. I was able to retrieve about 15-20 of the fry.
20 May 2014 - Spawn 3 laid. 5-7 fry from Spawn 2 remain.
25 May 2014 - 3 Remain from Spawn 2.
29 May 2014 - Spawn 3 hatch. Was only able to retrieve 3 fry, my bangaais made quick work of the fry before they could get to the surface.
30 May 2014 - No fry from Spawn 3 remain.
1 June 2014 - Spawn 4 Laid.
Spawn 2 in Detail:Spawn 2 is the only spawn so far where I have been able to raise fry.
For the first 7 days I fed rotifers, days 8-10 a mix of rotifers and baby brine shrimp, from 11 on just baby brine shrimp. Currently 3 clowns remain from Spawn 2, they have undergone metamorphosis and look just like little orange versions of their parents.
1 June 2014 - Spawn 2 at 15 Days Old
This picture isn't that great, but you can see that they are developing stripes.
