My lighting is not display quality so the pix are a little green, but you get the idea that they are no longer skeletal and they've got the tummy bulge.

Fantastic! They all look great!

Great job! I wish you the best of luck with these guys. I still haven't found any eggs with mine. The appear to be spawning every few days but I can never see the eggs. I need to get a microscope.

Blake, are you using spawning mops? If not, you should start just like I suggested for Kathy. Take out all other spawning sites and they should use the mops (again, this is all hypothetical at this point, based on my experiences breeding Lamprichthys tanganicanus (spelling?)). You won't need to "see" the eggs, you'll simply find the hatched prolarvae 50+ hours later Matt

Matt, the pair is in a tank with live rock and macroalgae so I don't think I could remove all other possible spawning sites without leaving the tank bare. The good news is that they seem to favor a powerhead that I have left off and has been covered in caulerpa. Next time I see them spawn on it I will remove it. Should a 10 gallon with a air stone suffice? They usually spawn in the evenings but I'm sure they're spawning more times than I observe. I always see them courting but as you know the actual event is so short.

Yesterday I noticed the female looking like she had "swallowed a marble". I put a spawning mop in the tank. This morning, sadly, I found the female dead with a sore on her abdomen. I'll try a dissection later this morning, but I can't imagine what happened. Egg bound perhaps?

Sorry to hear it, Kathy. Are you going to try again?

I still have a female in the tank next door, so yes, I will try again.

The male she was with is also a little funny, as his top spike fin is shortened, for no apparant reason. I tried to put the male in with Thin Female, who is no longer thin, and is actually larger than the male. She has not taken to him very well, so I sequestered him in a pond basket in her tank so she can see him with out being able to attack him.

Ah...the joys of pairing semi-monogamous fish. I suspect the "interaction without physical content" is a good idea - good luck!

Any ideas about the shortened spike? The only predators in his old tank are bristle worms and aiptasia.

Amazing kathy...Simply amazing. The dedication going on with this group just shows me that this IS something that can be done. And i love the training method. Danielle used this back in 2004 when we were getting regal angelfish in for clients. We would quarantine them for 4 weeks and then put them in an established system with tangs. We found that the tangs and their aggressive feeding actually "encouraged" the regal angels to start taking frozen foods. Nice to see that others have found this to work also and it wasn't just a fluke of something we had going.

Sadly, the male has now died. I'm down to one female. The store I got these from has been looking for a mate for quite a while, but nothing yet.

Do you know what took him out? I've just started leaning more heavily towards "bacterial erosion" on that dorsal spike issue... I've found all the filefish to be very sensitive to water quality...not sure how heavily your systems are weighed down with organics. Might make sense to take them and run them offline on independent filtration, since it kinda sounds like you've lost two to bacterial-related issues???

Could be, and seems likely. I feed pretty heavily. I have been changing water regularly, but perhaps its not enough. The last female still is lively.

Sorry to hear about your losses Kathy, I have been following your thread with interest.

Thanks for the interest, EasterEggs. I put a bag of rinsed activated carbon in the sump under the water intake, so that should help with organics, and I'm due for a water change shortly. The "system" now has 2 fish in it, for 50 gallons of water, so I've reduced the automatic feedings as well. The system consists of 2 x 20 gallon high tanks, and a 10 gallon sump. I've removed the black ocellaris from both tanks. One tank now has a neon goby that will go elsewhere soon, and the other tank has the apparantly healthy filefish female, formerly known as Thin. I will soon introduce a pair of spotted mandarins to each tank, as well as a pair of spawning dottybacks in the tank without the filefish.

Well, I never moved the dottys there. The two mandarins introduced to the tank where the filefish died, also died, so I drained and bleached that tank after I took it off the system. It remains dry today. I may switch out the whole tank, as I am afraid to put anything in it. Fat Thin Female died for no apparant reason the day after I acquired a new-to-me pair from Kate B. Matt P. said he thinks these fish have a short lifespan and there is no telling how old the dead fish was. The new pair are in QT in my new system as I build around them. I think I may move them soon to the tank that Thin female used to occupy. The pair of mandarins, currently occupying it, are fattening up (the female mandarin is too thin to spawn, at the moment). The new filefish pair clearly love each other and are doing well, eating well, putting up with the constant traffic as I build around them. I thought i saw some pre-spawning activity recently. There is a small mop of cheat in their tank.
