Breeding Journal DataSheet
This first post should be updated regularly to include new information as events take place or changes are made to your system General Species: Oxymonacanthus longirostris Social Structure: Pairs Size of Individuals: about 1.5 inches Age of Individuals: unknown Date added to Tank: 7/20/11 , New pair 1/26/2012 Broodstock Tank Details Size of Tank: Two 20 gallon high tanks linked to a common sump. Substrate Details: live sand Filtration Details: 100 micron filter bag, large brick of fake live rock in sump, small powerhead to return to both tanks, small powerhead in tank aimed along the surface, to provide maximum efficient flow, live sand in both tanks, previously used to house pairs of clownfish for at least a year. Water Changes: at first, 5 % daily, as I am feeding these guys so frequently, and they are not eating everything. Later it will go to 5 % weekly when I am sure the biofilter is adequately handling the load. Water Temperature: 80 Lighting: room Lighting Cycle: 14hrs light/10 dark Other Tank Inhabitants: neon gobie in one of the tanks on this system, in 2012: pair of target mandarins only Broodstock Feeding Details Food Types: mixed shaved frozen bits of PE mysis and Ocean Nutrition F1 and pellet Otohime C1 , homemade mash Feeding Schedule: 4 times daily for pellet, once or twice for frozen. New pair: twice daily pellet, once or twice frozen Spawning Details Date of First Spawn: Spawn Time of Day: Dates of Consecutive Spawns: Courtship Details: Egg Size: Egg Color: Egg Count: Hatch Details Hatch Date: Hatch Time of Day: # Days after Spawn: Larvae Description: Larval Tank Details Temperature: 80 Size of Larval Tank: 17 gallons Substrate Details: bare Other Tank Decor: Filtration Details: central stand pipe, sponge filter, UV Lighting: fluorescent Lighting Cycle: 24 Water Changes: small daily Larval Feeding Details Food Types: Feeding Schedule: Metamorphosis/Settlement Date of Settlement Start: Days after Hatch: Date of Settlement End: Description of Fry:
Grow-Out Tank Details Temperature: Size of Grow-Out Tank: Substrate Details: Other Tank Decor: Filtration Details: Lighting: Lighting Cycle: Water Changes: Size at Transfer: Age at Transfer: Grow-Out Feeding Details Food Types: Feeding Schedule: Additional Information (No Pictures or Videos in the Section Please) Miscellaneous Information: I purchased these two pairs from a local store that employs a young man Kyle who took an interest in them. When I saw the first one in the store it was emaciated, and I spoke the manager about her. She seemed doomed. He was aware of strategies to save this fish, but I did not have much hope, given her condition. The next time I visited the store, she was a mated to a male in that tank, and their bellies were rounded. Kyle had followed Matt Pedersen's recommendations, and had trained these fish to eat frozen PE mysis. The next time I visited the store, there was a second pair, who, having watched the first pair, in the adjacent cube, strike the mysis, began doing so themselves. So now there are two pairs of mated, mysis eating filefish. How could I resist? I got them all. The first pair is plump, the second, less so, but having two pairs increases my chances, so here goes.  The store had purchased all these fish from Quality Marine. They were keep in mild copper system to prevent disease. The third pair was obtained from Kate B., shipped to me from Portland, OR. You will be required to provide photographic or video evidence in this thread of each event submitted for the MBI Program.
If your thread does not contain these photos the MBI Committee will not be able to approve your reports. PHOTOS AND VIDEO S MUST BE PLACED IN ADDITIONAL POSTS, NEVER IN THE FIRST POST IN A JOURNAL.

They'll be fat and happy in no time so long as you get them feeding 4-5 solid times per day. You can totally do these Kathy. Remember the spawning mop thing too. FYI, since they spawn on a rock, you might try attaching the mops to a tile base or something and cutting them short. All they are is acrylic yarn wrapped and cut to make a "pom pom" of sorts...you should be able to modify easily for one that's short and is wrapped on a tile (i.e. to be similar to the gracilaria on the rock). Or you could try hanging ones like they use for Killiefish

Thanks Matt, Right now I just wanna make sure they will fatten up. I've noticed that they strike at whole mysis, but can they chew off bits? Do they have teeth in their mouth tube? I took some frozen mysis and grated it with a fine grater, and offered them that. They seem to go for it, and its small enough that it can go down the tube mouth. Pair one has a normal silouette, and I can see them striking at food whenever its offered. Female from Pair two strikes at food as well, but Male Pair 2 is showing signs of starvation. He cruises the glass, and seldom strikes at bits passing by. Both fish from Pair 2 have thin silouettes, but the male is most skinny. I've tried live pods as well, tiggers and M salina, but I'm not sure they are going for them. I'l see if I can get some more browned acroporas. If so I may be able to keep Male Pair 2 alive long enough to complete his training. I've trained my daughter to feed them while I'm at work. She'll do well.

I have absolutely no knowledge of this type of fish. Sounds very interesting. Tagging along!

i just spent the evening reading a long thread on RC about bulking up these fish. Then I dug out the nutrimar ova I've had in the Freezer for a couple of years. Lights are off now, so I'll try some in the morning.
As an aside, I was gone on Saturday so none of my current broodstock got fed for a good day and a half. Since I got these filefish on Sunday, and have been feeding them every few hours since, the rest of the broodstock have been getting their regular feed plus the leftover from the filefish. Yesterday one pair clownfish spawned, and today two other pairs spawned, the biggest nests they have ever produced. I should go away more often, or else the size of the spawn may be related to how much they eat the day before….now to find some rotifers….

I could have given you rots.

Tal, you are too kind. I can always get rotifers from my professional zebrafish research guy at the University. Give a guy a pair of clownfish, and he gives you a supply of his excess rots whenever you need them.

Remember, they are still in the filefish family, which has teeth like triggerfish, puffers etc. The opening is small on O. longirostris, and the teeth appear (from the naked eye) to be designed to "snip" off polyps. They use this snipping mechanism to munch down flakes and pellets, and yes, they can tear through a mysis once they've learned how. Nutramar Ova, if you can get it (and I see now you already had it), and Rod's Food - two really good "first foods" to try. Another (adding an edit here as well) - minced squid. I neglected to mention how well it worked for my Larvatus when first training them. Matt

hmmmm….teeth but no jaws. How does that work for them? I wonder if Witt has any wisdom on how this tube with teeth thing works. He's been studying fish mouth mechanics.

Went down for the morning feeding. Skinny male looked to be pinned by the current to the dead acro. He didn't look too good yesterday, but I thought he would live a little longer than this. Sad.
Got the food ready. started feeding the tanks. Skinny male never moves. Not even a little. No, he's not sleeping, he must be gone. Sad.
So after a few more minutes, I reach in the tank and take his lifeless body off the acro gently by the tail and set him on the aquarium lid...
He moves. !!!!!
I drop him back into the tank and he swims to the acro and starts picking at it like nothing happened. He and female interact, and he keeps picking the acro.
!!!
Apparently, he's still alive. How would one have known?
Still too skinny for comfort, still not sure he'll make the transition, but, for now, still alive.

How fun! The best of luck to you Kathy!
I hope the thin male makes a full recovery.

How did the Ova go?
Don't give up on him, Kathy! Sometimes it seems like you keep them going by willpower alone. Keep trying everything. Live mysis sparked interest in mine even though I don't think they ate any.

The Thin man is not looking good. He soon disappeared and when I came home from work he was still disappeared. I had to hunt for him, he was resting, and I got him to swim briefly but then he disappeared again.
The ova was met with indifference….
