Heres an update. The adults are doing great in the main display. Eggs began appearing on February 24th. The first hatchling appeared on March 29th. I now have 8 hatchlings and probably 30 eggs that look ripe. So maybe a total of 40 will be hatching from 100 or so eggs.
I currently have more eggs laid in the main tank that I have not removed yet. Maybe 60 or so.
Studies have shown cephs reproductive success and egg viability to be dismally low in captivity with percentages at around 10%. It is difficult to determine what affects this without having multiple seperate tanks with different conditions. For a month, I kept a mated pair in the juvenile section of my tank to try and document its breeding and egg laying. Most of the eggs from this pair were not viable. At the same time, a female that was mated with an older male (from a different source of eggs then the others) seemed to have much better success. However, I cannot contribute this success to this or the different conditions in the main tank. They share the same water, but differ in flow, rock structure and lighting
At present, all adult bandensis are in the main display. 6 adults. I can see cluster of eggs that seem all bad and another cluster of eggs next to it that look all to be good. I cannot discern between if they were laid by the same female or by seperate ones.
Water parameters:
-Nitrate 0
-Phosphate 0
-CA 460
-Alk 11 DKH
-Salinity 1.026
-Temp 76-78
-Mg 1260
-Flow: High- 2 vortechs on reefcrest -synched
-Lighting: 3x 250 watt SE Halide + 4x36watt T5
T5s on 9:30Am-8:00PM
1x250 Watt SE halide on 2:30pm-8:30pm
2x250 Watt SE halide on 3:30pm-11:30pm
I will have hatchlings for sale soon. These are captive bred and are 2nd generation. I will like for anyone interested in purchasing them to update thier experiences on Tonmo so we can track lineage as well as add to our knowledge of successfully breeding them.
