Feeding Schedule: twice daily Additional Information I grew these out with a few neon gobies that I raised shortly before doing the Clarkiis. (No Pictures or Videos in the Section Please) Miscellaneous Information: I got this pair from The Corner Reef, an aquarium store a 40 minute drive from St. Louis. They were a trade in, and reportedly spawning in the original owners' tank. You will be required to provide photographic or video evidence in this thread of each event submitted for the MBI Program.

These fish adapted well, and surprisingly, their tails turned bright yellow the next day. They are quite a nice looking pair after all.

Whoo Hooh! The pair spawned while I was at MBIW2014! Amazing that they spawned so quickly after I got them, 2.5 weeks! Judging by the color of the eggs, I think it was on Friday afternoon, 7/18/2014. I didn't have the chance to look at them that morning as I was heading out to work early so I could leave work early to catch the plane. My kids fed them later. Don't know how gravid she looked, but I am thrilled to have eggs so soon.

Oops. the eggs are gone today. Don't know if they were eaten or if they hatched earlier than expected. I'll know to check for eggs next time, and have an exact date.

Spawned again. This time I know when. Hopefully they won't eat them, and I'll have a hatch on Sunday.

They hatched on Saturday, at least some of them did. In fact a whole lot of them did, although there are still a lot on the pot, I gave them back to their parents for their feasting pleasure. I have most of the hatchlings in a bleach sterilized 15 gallon glass tank with RGreen and rotifers, air, and heater. I decided at the last minute to put a few in with the copepods in the "damsel" tub that recently had a huge die off(no surprise). I also put a few in with the neon gobies, most of which are a couple of days old (some are 10 days old) in a rotifer stocked BRT with a drip recirculation to a sump with a protein skimmer, sponge filter, 53 micron rotifer filter. The gobies get roti green and rotifers with some parvocalanus, the damsel tub is all parvocalanus and pseudodiaptimus and live phytoplankton, although I did add 10 drops of Rgreen to increase the greenwater for the clarkiis. So there you go, clarkiis three ways: rotifers static, rotifers recirculating, and copepods.

Larval tank #1 had some early die off, but the remaining larvae look like they are eating. They don't look as well as the larvae in tub @ 2 with the neon gobies and the rotifers and some few copepods, or the remaining single larvae in tub #3, with the copepods. All 3 trials had early die off. These last two trials' remaining
larvae look plumper and more dynamic. To be fair, however, the tubs are a degree or two warmer, and their lights are on 24/7, unlike tank #1.

Larvae in tubs 2 and 3 look well, and close to meta. They are opaque with silver bellies and a darker mark to the rear of the belly.

Is there any reason you chose to light 24/7 and keep the temp higher with the copepods rather than the rotifers? The reason I ask is when I was working with P. fridmani Witt suggested that it would be beneficial to give them 24/7 lighting if I was feeding only rots (so they would eat more of a less nutritious food source). He also said that if I switched to copepods I could give them a day/night cycle since they were a better food source and wouldn't need to be eating all the time.

Reasons to light or not to light 24/7: My reasons are more about convenience than science. I already had the tubs started with rotifers for the neon gobies(tub #2), and copepods for the damsels(tub #3), and they seemed to do better with 24/7 lighting. Both tubs are located at the far end of the basement from the brood stock tanks, which need the dark nighttime. The glass tank with rotifers, larval tank #1 is next to the broodstock tanks, so that one needed to be dark at night. The actual plan for the clarkiis was to put them all in the glass tank with no other fish larvae, and raise them like I have always done with ocellaris, on rotifers and RGreen. For various forgotten reasons, I hatched some of these clarkiis in a bucket, and then decided to put the pot of eggs into the tank to hatch overnight. I used the ones that hatched in the bucket to distribute larvae to the other, already running, tubs, just as a lark, to see what might happen. As for temperature, it is difficult to predict what my heaters will do at a given setting, so I set them for close to what I want and adjust from there. I had not planned this as an experiment, so I did not adjust much or try to match the temperature between the tank and the tubs, I just recorded what it was for this report. 78-80 range is reasonable so I didn't adjust, I just recorded the data. In the end, I don't think the differences in the temperature amounted to much difference in time to metamorphosis or anything else. The 80 degree one was a day ahead, but it didn't really make that much difference.
