My maroon clown fish pair recently began to spawn again.  Unfortunately for me they are spawning on the glass which makes the collection more difficult.  I used to use the bowl method where you would use a flashlight to attract the larvae then scoop them out with a bowl.  It was time consuming and you will kill some larvae in the process.  I have seen some commercially available products called larvae collectors but read about a guy selling a DIY one.  I picked one up off of the marine breeding initiative site.  The way it works is that it is...

My first two batches of Onyx Percula clownfish have hit 10 months old and are looking pretty good.   They are getting some interesting patterns, and are beginning to develop their black coloration.  Most of them are close to 1.5 inches in size.  One thing that I think is interesting is there are two different color variations that seem to be showing up.  One variation has a darker orange coloration and the other ones are very light orange almost yellow coloration. From what I have heard this has been seen with some other peoples Onyx Percula clownfish.  I plan to keep...

Well I have been having some struggles with clownfish larvae dying the first night after hatch.  This time I tried mixing using a  50/50 mix of  water from my brood stock system and freshly made saltwater.  It seemed to make a big difference as I had about 75-100 clownfish larvae alive after the first night.  Over the next 10 days I lost some but I still have around 50 or so left that went through metamorphosis.  At this point they are looking pretty good and eating a ton of food.  I am using TDO size "a" dry food and newly...

My Onyx Percula clownfish spawned recently and I hatched the eggs in a half full 10 gallon aquarium.  I have been having some problems with the clownfish larvae dieing in the first 8 hours after hatch.  I usually take the water out of the brood stock tank and use that for hatching the larvae in the larvae tank.  This time I used 50% newly made saltwater and 50% water from the brood stock system.  For this batch I ended up with 60-70% surviving the night and after 5 days I have about 50 larvae left getting close to metamorphosis.  This...

Two nights ago I finally had the opportunity to watch my Onyx Percula Clownfish spawn.  This pair is around 5-6 years old.  The pair is the offspring of Rod's Onyx clownfish.  The spawning started around 7pm cst and lasted a little over an hour.  A nest of 150-200 eggs were laid on a hammer coral.  They typically spawn every two weeks.  The eggs hatch 8 days after they are laid around 2 hours after the lights are shut off.  The pair of Onyx Percula Clownfish are in a 30 gallon cube tank that is attached to my main 240 reef...
