Royal Gramma

No mucho, mijo!

The company I worked for used pairs, a harem will be hard to control,

I have some pairs laying but I ussually let the first spawns go, the best way is to place a medium size one with a small one, the med. will grow more, the small one will remain almost the same size.

There was this lady with a spawning pair a few months back:

Thanks Ed. That thread doesn't really end well - since we don't know if she was able to raise fry to juveniles. Seems like all the material I've been reading points to that kind of end in most people's homes.

Do you think not using RO water has something to do with fry not growing to at least a juvenile phase?
 
The biggest problem with that kind of larvae is nutrition and or physical enviroment.

I don't think the choice of water had anything to do with it.

Thanks for your responses Ed. Seems like the guy trying to breed Mandarins is having a hard time also. I have a book on how to breed Clown Fishes by Joyce D. Wilkerson. I'm going to try and breed Royal Gramma based on her techniques for Clown Fishes. Interestingly enough, as I read the thread on the Mandarins, I noticed that the guy keeps loosing fry at 3 to 6 day range. This author says that the most likely culprit for loss of fry at this age is: Lethal side lighting, Improper food size, Improper food type and Low food density.
 
You are right. According to Joyce D. Wilkerson, author of Clown Fishes - a guide to their captive care, breeding & natural history, she says that those two are some of the reasons why fry losses are experienced at the 1 to 6 day period.

Hey, thanks for your replies. Hopefully, I'll post my journey into breeding Royal Grammas some time soon.

That book only applies to clownfish, RG are a different story and the rearing techniques although similar are not the same.

Oh, one last thing Ed.

Why do people make such a big fuss about RO water? I suspect a lot of people just mix their tap water with salt and dechlorinator and call it a day. Is there any real advantage to using RO water? I used to have a 125 FOWLR and I used RO water. Now, I'm just using tap water for my 75 FO. Also, I'm not using a skimmer this time in my FO. Will that make a diffrence?

Lots of questions but you have industry experience and I have part practice and part theory as expereince.

Thanks
 
I think that is mostly reef keepers who need to avoid all nutrients that come with tap.

Well if you are not using a skimmer and tap water you will grow more algae in the tank, the fish will be alright.

For larvae you should use a filtration before using the water, larvae require exellent water quality and are very sensitive so the more things on your favor the better. I use deionization, RO is to expensive to run. I know some that raise larvae with tap water with no problems, I guess depends on where you live.
