Additional Information Miscellaneous Information:
9/7/09 Maroons lay eggs in a clay pot
9/13/09 Moved the pot into a ten gallon tank filled with 7 gallons of water at 1.020 salinity
9/14/09 Eggs begin to hatch around 6:00 P.M. about 300 fry
9/17/09 Ammonia spike kills the last 2 clownfish fry
9/17/09-10/2/09 Let eggs on rock hatch realized that it would be easy to siphon clown fry out of main tank into another tank siphoned none due to improper preparation
10/2/09 Maroons lay a new batch of eggs on rock I begin to prepare for the hatch
10/8/09 Siphoned baby maroons out of tank 200 babies captured the eggs were caught by shining a flashlight into the tank the babies were attracted to the light so they swam into it I was then able to siphon them into a bucket and move them into another tank the salinity in my main tank is 1.025 and the salinity needed in a broodstock tank is 1.020 I set up a slow drip of water and dripped water into the tank over night
10/12/09 have about 30 babies left from previous hatch the maroons laid a new batch of eggs today
10/17/09 went to fishtal's MASM meeting on captive breeding it was very informational thank you for all of your help Tal
10/18/09 I moved the clowns out of the broodstock tank into another 10 gallon tank this gave them a fresh start and allowed them to get out of the water that had a 4.0 ammonia level when I moved them I transferred them to the new tank with 50% of their old water. The other batch of eggs hatched I moved them into the tank that I had the other clowns in before I cleaned it before I put them into it I siphoned about 200 babies
10/20/09 1 maroon from the hatch on 10/8/09 goes through metamorphosis and gets a stripe and is the color of it's parents
10/21/09 a the same maroon gets a second stripe 2 babies left from this hatch I did an 50% water change on this tank to bring the ammonia level down to 1.00
10/22/09 I did another 50% water change to bring the ammonia level down to .50%. Did my first siphoning of clowns from 10/18/09 tank noticed about 20 dead fry ammonia level was .25% after change
10/23/09 still have 2 maroons from hatch on 10/8/09 waiting for the second to go through metamorphosis it is beginning to get longer and turn black. I still have about 80-100 babies from my hatch on 10/18/09 this is three times more this same time on my hatch from 10/8/09
10/24/09 maroons lay a new batch of eggs which will be hatching on 10/30/09
10/26/09 hatch from 10/18/09 are going through metamorphosis tonight, and my clown left from the hatch on 10/8/09 now has three stripes
10/30/09 all clowns from hatch on 10/18/09 have gone through metamorphosis, and another group of clowns hatched I siphoned about 250 out of the tank
11/1/09 all of clowns from hatch on 10/18/09 have 2-3 stripes and I have one clown left from my first hatch it has 3 stripes, all clowns are .5 cm long I still have about 40 most are eating flake food, and I still have 250 babies from the hatch on 10/30/09
11/3/09 clowns laid a clutch of about 50 eggs
11/13/09 clowns laid another clutch of about 600 eggs in the pot for the second time
11/18/09 moved clowns that hatched the 30th into the tank with the older ones. The eggs in the pot should be hatching tomorrow.
11/19/09 Moved pot over to the tank where the babies would hatch, after a series of long events the next morning I ended up with 20 larvae
11/23/09 Clowns laid eggs on rock, I need to get them moved into a broodstock tank ASAP but it probably won't happen until after Christmas
11/29/09 Clown eggs hatched I got about 400-500 fry
12/3/09 Clowns laid eggs
12/9/09 Clown eggs hatched
1/3/10 Clowns laid eggs (I will not be able to save this hatch because I'm going to be gone for the weekend)
1/15/10 Clowns laid a clutch of eggs in their pot there are about 600 eggs
