Added in more RotiGreen. For some reason, the babies are all alive apparently, but most are swimming at the bottom. This ordinarily suggests that the light is too bright, right? Time to make an adjustment...

Time to make an adjustment... I've not used RotiGreen. I've seen larvae hang out near the bottom, or sides, in two instances... In the morning soon after the lights come on, still sleepy. If the phyto isn't "green" enough. In my use of GW, if I can see the bottom, it's not dense enough... if I add a bit more that gets them back into the water column right away. I start cutting back on phyto after day four when I start Oto A. With my last batch of regular A. ocellaris I got ahead of myself and added the sponge filter on day 7 instead of 14, with no ill effects.

Tal, I'm gonna ask you to elaborate a bit further on your density of phyto in your clowns. You add enough so that you can't see the tank bottom, but how deep is the actual water column when you're viewing from above. It looks like overall, the babies are alive, and more are up in the water column at this point. As both Tal and I have kindof alluded to, this is probably a lighting intensity thing now (but it certainly wasn't when they initially hatched last night). I see very few if any dead fish so far... Matt

With my clowns I start with a standard 10 gallon that's about half full, so 5 gallons. Over the next 14 days I increase the water volume when I siphon out detritus until it's about full. At half full I don't want to be able to see the bottom. I've never used a sechi disk to be that exact, I just eyeball it. Like I mentioned, if I see them start to hang out near the sides I add more phyto and that does the trick. It is at this point I start to see the bottom too... I'm no expert but I disagree with it being a light intensity issue, I see it more as a visibility issue... unless you're blasting them with a 500w MH bulb Edgar uses those super bright work lights for his dottys and swears by them but dottys are a different case.

Have been dripping in clean new SW. Added 30 more drops of RotiGreen...it's now REALLY green in that larval tank. Seems to have done nothing to get the babies on the bottom up off the bottom though. Keeping in mind the wise advice of Kathy Leahy who reminded me that Black O's are prone to misbarring, which means I'll have to pay close attention to water quality over the next couple weeks. It DOES look like overall I have a good healthy batch going. I checked the tile and most of the eggs on it are still viable, so that could mean a hatch tonight again???? Stranger things have happened... Matt

Did you explain you larval set up for these guys? I may have missed it... I agree with Kathy that Darwins are more prone to misbarring I'm not sure why. My fisrt batch had a high percentage of misbars (80%) while subsequent batches have been completely the opposite (10-20%). Raising protocol hasn't changed.

So right before 8 PM, I turned the larval tank lights off, left the little LED on. I checked just after 100, pulled the tile up and out, and there were only maybe 10-20 unhatched eggs on it, which I can only assume means that the rest in fact HATCHED?! I could be pulling a massive brood here...crazy to think about. Rotifer population is looking low, so I'm going to pull some more an hour or two after their feeding. I pulled out the tiles, and have left the larval tanks lights on.... Really curious to know how many babies I have because at the moment, the water is too green for me to even get an idea (but judging by the number congregated around the LED, it's safe to assume there are more than 20 ) FWIW, Matt

OK...so I removed maybe 2 gallons of water this evening, and in the process, even though I tried like crazy to avoid them with my airline siphon, I still got 20 larvae! Crazy. Water is clearing up a bit, and they seem to be making a huge dent in the rotifer population all the same. So tonight, after the water change, I enriched a gallon's worth of rotifers with Selcon for a few hours while dripping in another 1.5 gallons of clean new saltwater. It looks like I'm gonna easily have one of my best batches of clownfish ever unless I screw it up. Not a bad way to rear my first batch of Black O's...

Yeah, they are curious little guys even at that age. They love to check out the siphon tube. I assume you were siphoning detritus? I'm sure I'm not telling you something that you don't already know but, I always siphon into a white bucket so I can see th stray ones. I let the waster settle a bit then use a pipette to snag them back out. Sounds like you have a good batch going!

This morning, just a note, I put in 10 more drops of RotiGreen. I would save I have conservatively 100 clowns, but possibly 200 at this point. Oh and Tal, yes, I was siphoning detritus and dead babies. I did just as you did, 'cept my bucket is orange. They still stand out.

I have a hard time seeing them in an orange bucket... maybe I'm thinking more of the P. fridmani.

Maintenance updates. Yesterday, drained down to about 5 gallons of water and then dripped back in a gallon. This morning, added another 20 drops of RotiGreen, as some (but not many) babies were starting to nose up to the BLACK SIDES of the tank?! Crazy. There is still a definitely issue with larvae dieing off...you can tell which ones are gonna die because they are thin, swim sporadically, and turn pale and lose attitude control in the water. Meanwhile ones that are doing well are robust, fat, and look fine - the swim in the air currents just like "trout in a stream". What's causing losses at this point? I don't know. I took some pictures last night, which I'll post sometime later today. Matt

So I've been a bit busy with my folks coming into town for the weekend. The evening of the 25th, I trickled in 1 gallon of new saltwater, drained out 2, trickeled in one more, and added 20 drops of RotiGreen and 10 drops of Chloram-X. this morning I had to harvest a gallon's worth of rotifers for feed. This evening, around 9 PM, I checked on the larvae and found that ALL the rotifers are gone...the babies had cleared out the tank. So...harvested 1.5 gallons worth immediately, enriched another gallon's worth for about an hour with Super Selcon, and am dripping in 1 gallon of clean new SW with 10 drops of RotiGreen and 10 drops of Chloram-X. It does not appear that there are any deaths today...so maybe that part of the rearing journey is behind us? I need to post pix too...they're forthcoming.

Only pictures worth showing were shot on 2-25-2010 at 12:37 AM (so just after midnight):

Ok, really stupid question but it's been a long week... are you covering the non-painted end of the tank?

Matt: Not to side track your thread... but since I noticed you also had a split hatch, let me tell you what I did and I was surprised. I have "half black photon" pairing - Original Onyx perc with its black photon pairing. They are in my overflow box of the big tank, and spawn erratically. This nest was large enough, in a time window where I could raise it for at least 2 weeks before leaving for a few days, so I decided to raise it. The temp in the parent tank is 75-77F. The eggs started to look silvery after 8 days, and not wanting to loose them I took the tile out into a separate tank. Of course they did not hatch that night. So, in the morning I took the tile and put it back with the parents, wondering if they would care for it as if nothing happened. To my surprise they did. So the next night - day 9, I was sure they would hatch and again pulled the tile at night. Came back in the morning and only 1/2 the nest had hatched. So once again I put the tile back with the parents, and they went about it like the tile was never missing. On day 10, pulled the tile again and got the remaining to hatch. I was rather surprised that I did this 2 nights in a row and the parents were fine with it. Wonder if its just this pair, or any other clownfish pair would do the same. sanjay.
