Sphaeramia Nematoptera vs Kaudernii Breeding

Has anyone had luck with the PJ cardinal or are they harder than the Banggai?
I haven't seen any success stories here. Am I missing them?

Hi

PJ's and just about every cardinal for that matter are harder than Banggais.

PJ's (and others) have a true larval phase, just like 99% of other marine fish. They have been cultured before but mostly on wild plankton. This creates and extra level of difficulty and the reason you dont see many/any success stories.

I worked on them without live plankton and got to about 20 days but nothign ever settled.

When you say wild plankton does this mean they are grown out in the ocean in special areas?
I don't guess this would be a good fish for the first time breeder then, regardless of the phyto types the he/she has growing?

Wild plankton means they go out in the ocean on a boat, tow a plankton collector around for a while. They then sort out the stuff from the catch that will make good food (usually they are looking for copepods of the correct size), and add that to the larvae tank.

they can also collect plankton from shore, normally in high flow river mouths etc. Bit of hard work.

ORA has grown them. I don´t think they collected wild plankton, did they ?

I got Apogon leptacanthus to 40+ days without any wild plankton. Copepods are probably crucial. Tisbe, Tigriops, two easy types to start with. Of course, Calanoid types are better.

I think it is possible, and as more people keep trying, they will be unlocked (at the hobbyist level). Commercial producers can already do them, and Witt included them in his book. Definitely possible.
