Hey Tal. Mine have spawned in as few as 2 after the last eggs hatched. In your first pics the eggs had been there for several days as the eyes were developed. I am wondering what the incubation time may be due to the reduced temps. Mine are in a tank in my main broodstock system and spawn regularly at 80 deg F.

There is no way the first eggs were there before the 25th. I did a 100% water change and cleaned the pvc with a toothbrush. I compared the pics from Sat and today to make sure the pipe hadn't simply rolled (the new clutch is located a bit "higher" up the inside of the pipe and less visible) but that wasn't the case. There is a nick on the end of the pipe, from cutting, that is in the same place in all pics. Witt points out that they like cooler temps, no heater in the tank, but it is covered with a plastic lid that may retain some heat.

Don't let too much time go by before you start hatching nests. These guys have a relatively short lifespan, and they can stop spawning before you know it.

I know about their short lifespan. Have you ever had this happen before?

How long are you going to wait until you pull them

The broodstock stopped spawning, and I never got the progeny to spawn. This may be due to something other than their short lifespan. That said, one of my original fish is going on year 4, fat and happy. How long is their lifespan? I've recently learned that they need a period of cooler temps to spawn, and although I've tried this once with my current group of 4, no spawning has occurred. I am presently trying it again. 72 F for a week or so.

I put a thermometer in to check the temp. There is no heater in the tank so I'm assuming it is mid 70s. Matt posted this info on my facebook wall and wanted to share it here: Matthew Pedersen "Yeah, incubation periods can actually be measured in thermal units. They call it cumulative temperature or "degree days". In other words, the rate of development is directly tied to temperature (slower at lower temps)...this is why warmer temps cause Harlequin Filefish to spawn later in the day, whereas cool temps push it to earlier in the day (because the filefish intuititively adjust the spawn time to result in a dusk hatching basically...so cooler temps = more dev time = spawn earlier to get the same ending time."

Apparently my temp is a bit higher than I thought. If the digital thermometer on my TDS meter is correct the pico is running at 84°F or 29°C! I've been keeping the fishroom door closed and didn't realize the temp was that high. Air temp is 27°C. I was going to wait until tomorrow to pull the eggs but I'm thinking I should do it tonight.

At least that dispels the theory that they spawn better at cooler temps then.

Nice pics Tal! I'm wondering if having 6-8 in a 10-20G tank with pvc wouldn't be a bit easier for egg production/collection? If they are spawning that fast for you, heck you'd be getting 2-3 nests a week
