Kathy, how do you use the UV on a larval system? Is your system flow-through? What strength (watts, gph) are you using? I'm wondering if I should try a UV on my Orchid larval system too, but am a bit confused how I would incorporate it. Mine is flow-through. I worry that the turnover through the BRT is way too low for the UV to be very effective.

Low flow is better for effeciveness in that it kills all the bacteria in the water flowing through it.. I have a small uV plumbed into the return line from the sump.. In my case, the sump is a 5 gallon bucket.

A couple of weeks ago, I moved the pair that had been in the growout system to the broodstock system as I thought they were healthy. They had their own cube. Sure enough , the move did not deter them from spawning on schedule. I was so happy. Then this morning I found the male dead. No apparent reason. Go figure.

sorry to hear it. Are you going to replace it?

Yes, I did. I'm not sure the pairing is a good one yet. I bought a young unmated pair from Sustainable, and sure enough, one died within a few days of arrival. The other one thrived. After QT, I put the two singletons together, and they seem to like lunging at one another. Neither one is getting caught or seems terrorized, and they seem to ask for it more often than not. There are lots of hiding places in the tank, that the fish decline to use. One is much larger than the other. The supposed female from the original Pair #2 is the larger fish, which may be why they are lunging at each other instead of getting along, but I am not sure that dottyback pairs get along at all anyway. I am not sure if they change sex, and the prolonged period of loneliness may have changed the supposed female to a male. Why single fish seem to die on me: I think I may be trying to keep them in too close quarters. I think 20 gallons may be the minimum for a happy couple. Dang. I should finish cleaning up the 20 gallon tank of death(it has been bleached and dry for a month now.) That can be their new home. On another note, the Pair #1 has spawned again, I saw eggs yesterday, even though the female remains tiny and not great looking…If I get my act in gear, I can have a BRT ready for taking the eggs today, and try to artificially incubate them. I have no confidence that the male will not eat them.

My little female used to hide in a Turbo Snail shell. She stayed in there most of the time. Anytime she came she was harassed by the male trying to entice her into his cave. He would get frustrated after awhile and go after her, then she'd hide in her shell again. From what I understand, all Orchids start as females (or possibly unsexed), and the dominant one changes to male. Witt suggests sex change from female to male in his book.

So these two may be trying to figure out who is the male. The bigger one seems to be a bit more aggressive, so I hope it lands on him.

The male of Pair #1 did not eat the eggs yesterday, so I have been preparing a BRT. I hope to artificially incubate the eggs this evening. I am making a stand for the rotifers container and a BRT.

I'm getting better at this stand building thing. Finished it, minus the paint, in one afternoon. I pulled dottyback pair #1's eggs, or rather dumped them out of the home pipe. It's a smallish clump, but amazing, considering the size of the female. The eggs were not well developed when I looked under the scope, so I think they need another 2 days at least. I tried to use Witt's hatcher, but the air collected under the mesh until there was enough pressure to burst through the surface tension. This worked for a little while, but when I went back to check on the eggs after feeding the fish, they had popped out of the tube and were on the bottom of the tank. I put them into a brine shrimp hatcher with a drop of methylene blue, and a mild stream of air. That keeps the eggs gently moving and there will not be a chance they will escape the hatcher. The hatcher is partially submerged in the BRT, to keep the eggs warm.

I managed to hatch Orchid eggs out in a brine shrimp hatchery awhile back. I started with only 20 or so eggs if I remember correctly and got about 6 larvae. I think the air stream was too harsh though and knocked the larvae out of the shells a day early (seemed so in the development under scope). The larvae were really weak. If I end up tumbling eggs again I think I would add a short piece of airline tubing to the stem inside the hatcher and add a small air stone to get finer, gentler bubbles.

I checked the eggs this morning and there was only one that had a develped embryo in it. I think if it doesn't hatch tonight, it won't hatch. If it does hatch tonight, I'll have to put it in with some clowns I am hatching tonight as well, or perhaps into a goldfish bowl.

waiting for the hatch…also my clownfish that I'll test the new snagger with.

My snagger design had a major flaw and failed to snag, so I just did the flashlight and siphon trick. I had another nest as well to put with it and the two clownfish batches went into one tank to grow up together. The one dottyback egg did not hatch, so that was that. Yesterday, I noticed that Dotty Pair #1 has eggs again. I'll take a look tomorrow, and prepare for a hatch if the eggs are viable.

Nice pictures in the November 15th post, BTW, Kathy! Good luck with the new spawn.

The pair#1 with the small female is still doing their thing. They spawned an amazingly large bunch of eggs, considering the female is tiny. I've once again put the eggs in the brine shrimp hatcher in a tank water bath for temperature control, 2 drops of methylene blue, and when I checked the eggs there were many with eyes, beating hearts and body flexing. There were also many cloudy eggs that will not hatch, and some undeveloped ones. I'll have to work hard to be ready tonight, and my rotifers are recovering from a crash, so that will be an issue as well. Maybe I'll set up a goldfish bowl chrysel since I don't expect too many in this nest to survive. May 19, dotty eggs:

Well, they didn't hatch last night, and although I can still see some with good development, almost no yolk, hearts beating, they have not hatched this evening yet. I'll wait another hour before going to bed. BRT is ready for them.

Not sure exactly when they spawned. It was either the evening of the 17th or the morning of the 18th. Anyway, I think they will hatch this evening. I pulled 4 premies from the hatcher this evening. Now the lights are out, and we await the big hatch if there is one. I'll post the picture of the premies, in hopes of getting a hatching report out of this. After taking pix, I set them into the BRT. I can't help feeling that I'll never see them again…it's such a big black abyss. Click the video.
