View Full Version : Pajama cardinals spawned

I was surprised to find that my pair of Pajama Cardinals that I keep in my community reef tank had spawned and the male is brooding. I can't be sure, but I think that he has been incubating for the past 5 days, which was the first time I noticed him not eating at feeding time. I am not planning on trying to raise this brood since my male Bangaii is also incubating and I am set up to try and raise that brood. Just thought it was interesting since this is the first time I have actually confirmed the spawning for this pair in the two years I have had them. Still very cool to see!

Where do the Pajamas carry the brood? The girl at the ORA booth this weekend told me that they don't carry in the mouth like the Bangiis do. I love my PJ cardinals but I don't think that they'll ever spawn, or maybe they have been and I just never noticed.

That's partially true. They don't carry as long as Bangaii's do. The male commonly incubates the egg mass for 7 or 8 days in his mouth, then releases the fry when they hatch. The fry are dispersed and require the smallest foods (small-strain rotifers, wild plankton, etc) for the first 10 - 12 days. I picked up Matt Wittenrich's bible on breeding marine aquarium fish at MACNA this weekend and he covers the species in detail. Amazing book, I am soooo pissed I missed his talk!:doh: If you ever even thought about trying to breed and raise marine fish, you MUST BUY HIS BOOK! It totally rocks.

Sounds cool! If I ever settle down in a real house not a rented apartment, I'll definitely check that book out.

Yeah, pajamas are a PITA to get to sellable size. In fact, with the exception oif the Bangaiis (with their extended mouthbrood phase), all cardinals are.

I, too, like that book. I was lucky enough to get one of Matt Wittenrich's captive bred mandarins at MACNA. Its awesome. He had some there that were maybe 1mm! Mine is about 1/4" or so, and is devouring frozen food. AWESOME!

Darn you. I wanted that fish.

The Betas were cool.

I still want to see a speaker come to ARC to talk about breeding fish (hint hint).

Bob, where these the cardinals in the 55? Those were awesome. Very cool.

Bob can you shot me a link to the book your talking about?

Sure will Dawg. and yes Ace, that was the pair in the 55G (soon to be in the 210). I have had them about almost two years and this is the first brood I have seen. It's very likely that they have spawned in the past and I missed it.
Matt Wittenrich's book is "the complete illustrated Breeder's Guide to Marine Aquarium Fishes"

I agree with Loren, I also think that a speaker on breeding marine fish and Inverts would be a great topic for an upcoming meeting!

I think I may have a pair that breed as well but I've never seen and babies. I guess they get eaten upon release. I wasn't sure what was going on at first but one of my cardinals wouldn't eat and it looked like he had a full mouth. After a few days of this his mouth in no longer swollen and he eats like a champ. At one point I was able to see in his mouth and it looked all green. Are the eggs that color? This seems to happen several times a year. I have a 29L in my basement that's not in use. If that's what's really going on I may set it up try and isolate him there and see what happens...

That sounds exactly right! How old is the pair? They are prolific spawners once they mature and start, given the right conditions. The challenge with this species is raising the fry since they require constant supply of smallest prey. Some thing not easily available to most of us. But it is very cool to see and watch.

It seems like it happens all the time. In fact, there is an area under some live rock that is cleared away down to the glass bottom and now he hangs out there. I was checking him out the other day when he was out and the other (female) nudged him back deeper into the live rock. The biggest problem I'd have, other than feeding the fry, would trying to catch him without tearing the tank apart. Since he doesn't eat I can't lure him anywhere.

Definitley tricky! I'm in the same boat right now with my Bangaii male. I had to temporarily move them to another tank while I broke down the 55G I had them in while upgrading my reef tank to the 210. Of couse, now he is holding and in a tank that I can not easily get him out without tearing the tank apart. I may have to breakdown and just pull it apart to get to him but do not want to do it prematurely since I would like him to incubate for atleast 20 days or more. I'm setting up a 25G breeding tank in the mean time to hopefully get him out!
