My Black Ocellaris pair are spawning!!!

I went downstairs to feed this morning and this is what I found. One misbar over an inch long dead in the corner with no apparent injuries and one little 3/8" guy with a missing tail... I can't find any predators in the tank but I haven't had a death from this bunch (other than jumping out a couple times) in probably 4 months or so. I tested the water PH is 8.0 and ammonia is 0. Everyone else is ok. The big guy bit off the little guys tail and choked? I don't know.. I've never seen a clown inflict an injury like this. Nor have I seen any brutal fighting in my tanks at all. Ideas?

That missing tail is a bit odd, however, it looks like there is some other fin damage on that little guy that appears consistent with fighting. How many fish do you have in that tank?

Poor little guy. How does he get around with no tail? Looks like he was in battle. Maybe he's the one that took out the one in the corner (j/k). I've seen alot of bickering going on in some of my growout tanks but never to the point of an injury like that. Can't imagine that there would be any predetors in the tank.

I've never seen fin damage on any fish until this morning. I think it was done at the same time. I have about 250 fish in that tank. Its a 30 gallon with a divider to separate the sizes a bit.

He actually gets around not to badly and he's eating. No one is picking on him it seems so he may survive. Although he likely isn't sell able material anymore. If they start to pick on him I'll have to cull him I guess. I won't watch him be beaten to death. I can't imagine any predators either. I have a couple bristle worms in other growout tanks but I haven't seen any in this one. I've never had a problem with bristle worms harming the larvae either. I can't imagine any outside predators that could get in there either.. Its a mystery.
 
Well here's a bit of an update. I had my best ever hatch last night. Its about 500-600 larvae. There were 3 eggs that didn't hatch. This time I took the water out of my reef tank on the night of the hatch. I also bought a new 3" airstone and let the bubbles roll over the eggs. I was a bit concerned it was too rough on the eggs but it worked. Man they are eating me out of house and home already though. I hope my Rots hold up. I hope I get a good survival rate this time. No deaths that I can see so far today. Its hard to see when there are so many though.

I've increased feedings to 5 times a day in my growout tanks. I'd be interested to know how many times others are feeding. I'm feeding Oto B2 and C1 as well as flake food for the larger ones.
 
Great job with the hatch. This will sure test your rots.

I'm feeding a minimum of 2 times per day ussually 3 or 4 depending on what is going on.

They laid another nest tonight. Only days after the last one hatched. They are speeding up. My last hatch is still doing well. I have only lost about 20 that I know of. There must be 500 larvae in the tank. They have decimated my 3 rotifer cultures already. I've been feeding some Otohime A as well to supplement the rotifers. I did a 50% water change on my cultures today when I changed the water in my growout tanks. Hopefully they take off again. I'm going to go up to 4 or 5 bottles of phyto when I split this time. More phyto = more Rots.

I also ordered a drill bit so I can drill my growout tanks as a first step in getting them all on a single system.
 
Hi, this is such a fantastic thread, it helped me a ton. My maroon clownfish have been spawning and I decided to raise the fry. The fry just hatched minutes ago and started thinking how many days old do I take the black covering off the tank?
 
Well I'm getting some losses now... Partially of my own doing. I was dripping a water change last night and tried to fit 5 1/2 gallons a 10 gallon tank that had 5 gallons in it already... Well you can imagine what happened next. I only saw about 10 dead fish that floated out but I think there had to have been alot more. Also as they are going through meta my Rots shortage is starting to show. I'm getting some deaths now. They really kicked the crap out of my Rots. Now I'm trying to get the Rots to recover for the next hatch and I'm feeding this one Oto A and I tried some BBS as well. I am going to have to ration the Rots better next time. 500 fry go through sooo many. Are you guys keeping the density high all day or are you feeding to a high density and letting it clear before adding more to the larvae tank?

In my experience, huge nest that hatch and collected usually translate to huge crashes after a few days. Perhaps it is also the combination of stress / food / wastes all adding to the fact. Of course by huge I wasn't even refering to your 700 hatch size. For me, I usually put them in the same 5G tanks I am using, so of course that leads to much higher density, if you have extra tanks or buckets, try to split them into a few tanks/buckets/holders to see if it works out better.

good luck.

Being a breeder is definitely not easy nor too profitable. I can tell you that a few long time breeder friends I have:

- one has been breeding for 7 years and quit just now

- another one is much more lucky, breeding for 8 years now, he did break even after his 5th/6th year and he is already thinking of getting out after next year.

- of course there's RC's own Jhardman that become a professional gambler instead ;)
 
I haven't updated in a while so here it goes.. I sold 20 to a store a few weeks ago. He sent me a message a few days later and said they all had a heavy slime coat and were floating near the top. A few hours later they were all dead. All 20! We checked our water params and they were not too far off. (my nitrates were 80ppm but other than that not too bad) He drip acclimated them for a hour which is lots for clowns I think. They were in an open system with other clowns from ORA I think. We still don't really know what happened. It looks like Brook but his other clowns aren't sick. (neither are mine from the same batch / tank) Perhaps the stress and new environment weakened their immune system I don't know. Either way I'm going to replace the fish for him. I may ask him to setup a 10g for them or something if he's willing so it doesn't happen again.

The hatch that I was having great success with went downhill. I did a water change (drip) and overflowed the tank overnight. I was tired and forgot to turn it off before I went to bed. I think I lost about 200. I had run out of rots so I was starting to get some deaths. Still not many. I have maybe 200 from that batch eating Otohime A.

I've had a nest since that one that is doing so so. I had high losses on day 2. I have lots of Rots (go figure) and not so many mouths to feed now. Maybe 75. I have doubts about being able to sell huge amounts anyways so these smaller ones may be a bonus.. We'll see. I'm still at the point where I'm only getting small numbers ready for sale at a time (maybe i'm not holding on to them long enough) I've upped my feedings to help with the growth rate but I think I just need to be patient. Well that's it for now. I'll update some pics on the weekend. :)

Same thing with the thirty I sold. In the fish system he has problems. In a none fish system they thrive. I think the problem is our clowns have no immune system built up to wild diseases. So if just one wild fish gets through quarantine with a disease you can bet our clowns are going to get it.
 
" I think the problem is our clowns have no immune system built up to wild diseases."

I thought of this.. Why aren't his ORA clowns dead though?

"Does sounds awfully fast to die though overnight."

I think it was 3 days later. 2-3 days.

"How big were the clowns sold to the LFS? Rob's and FB's?"

1 1/4 to 1 3/4"

You know, now that I'm engaging the rusty memory, in the early days ORA did have problems with stores having their clowns get sick after being mixed in with store stock. I'm not sure how they actually solved that problem, but I do know it was a problem they needed to solve before they nailed that Petco contract.
 
ORA has the size to possibly expose them to some of these diseases. Other than a healthy diet what else could they have done?

Possibly immune system stimulants or some kind of vaccine. They've got the advantage of being associated with Harbor Branch.
