(No Pictures or Videos in the Section Please) Miscellaneous Information: Just a note: The broodstock came from Tod Miller's captive bred dottybacks. They were raised in a larger tank (55 gallon?) with live rock. The fish were 8-9 months old at first spawning, and they have been in my 20 gallon tank for about 2 months. The 4 black ocellaris clownfish don't bother with them. Another pair I moved in mid August, into a broodstock tank with better water quality, is not yet spawning 2 weeks later, however, the female is still very small.
I had tried to keep a pair of dottybacks with a larger group of black ocellaris clownfish (about 80 juvenile fish in a 10 gallon juvenile growout system) , and the black fish pestered the dottys too much. I had to remove the dottybacks. They seem to do best in a less crowded situation.
For pairing:
Pair 1)I put 5 in a 10 gallon (juvenile system) with no other fish and little by little, the dottybacks perished or were killed? until there were 2 left. Sometimes I found the bodies, sometimes I did not. No clue. The dead ones looked perfectly fine to the naked eye, so It is unclear how they were killed. The remaining pairs seem very healthy. They were moved to a broodstock system in mid August 2011.
Pair 2) Put 7 in a 20 gallon(different juvenile system), and the same thing happened. These fish were with the 4 black ocellaris. The blacks ignore them. This pair spawned at the end of August 2011. I was unprepared to raise them, and the eggs were eaten soon after spawning. The female of this pair died, and has been replaced with a captive bred female from Sustainable Aquatics, February 2012. Paired up 2/19/2012.
In all cases the females are signifcantly smaller than the males.
For the Hatching report, I am reporting on Pair #1. I hatched these eggs in a brine shrimp hatcher (Airline is glued into the hole in a cap of a 2 liter soda bottle. Bottom is cut off of the bottle, cap screwed on tight, and the whole thing was upturned in a 3 inch PVC T fitting. Flexible air tubing was fished through the arm of the T and the whole thing was partially submerged in a heated aquarium. Air was supplied to make bubbles. Clean saltwater was added, eggs were added and 2 drops of methylene blue was added. This bubbled for 4 days at 83 degreesF. Each day, I fished the eggs out to have a look under the microscope. In the evening of the fourth day, 4 premature dottyback larvae were swimming in the hatcher, and I get them out using a transfer pipet and took pictures on a plastic petrie dish through the microscope. Then I put the larvae into a prepared BRT.
