View Full Version : Pearly Jawfish pair

I've finally got a pair of jawfish cohabitating, so I guess it's time for a new breeders log.:yay:
These guys don't live very long, so I'm really hoping for some success rearing these. This pair was made from repeat trial introductions with different smaller jaws until these 2 didn't kill each other and quickly started sharing a den. They've been in the 20g refugium (dsb/macros) tank attached to the 58g display and 20g frag tank for 2 months. The larger male is quite dominant and the smaller female is rarely seen out of the den. But due to my ghetto engineering the tank hangs over the stand and I can see into the den from underneath.:thumbs: We are going National Geographic on this one!

So the female is out and about and the male is in the den with a mouthfull!

Edit:

Edit: We definitely have eggs. I've seen the male peak his head out and juggle the eggs.

Edit: So how do you get your fish to spawn you ask???
Simple. Feed,Feed,Feed!

Interesting! Is it really that hard to get them paired? I have 4, all of which share two different dens. Maybe I have two swinger couples:)

It definitely was hard for me. They don't change sex like clowns and are extremely territorial. I've tried several times over the years and this is my first pair.

Is there an easy way to sex them? As far as I'm concerned all mine look identical.

jamescook

None that I know of. In this pair the female is smaller and the male is bolder. He tears at the plants and patrols the den. He is now holding eggs as males tend to do.

Ya that's cool, I just want a type of lps to fill my "LPS" section of my biocube. I already have a frogspawn and a tricolor candy cane.

How long do they live?

2-3 years, usually, I think 5 in the wild.

Awesome!!!

I had one for almost 2 years, until I moved it to my girlfriends nanocube and he went carpet surfing before i was able to make a top for it.

no gsp

The male is eating and moving sand today. I don't see eggs in the den, so I bet this time is over.

jamescook
01-24-2012, 5:03 PM
So they're at it again. He's only been holding a day or two before he tosses em. This time I know he's set the eggs down and worked and then picked them back up. fingers crossed:huh:

How deep of a substrate do you have them in?

Sweet! What a cute couple. This is going to be National Geographic with that view into the den. Can't wait to see more! :thumbs:
And hopefully lots of babies in the future.

James, this is one of my target species when I get back in to breeding program again... please keep us posted so I cn learn from your success. Any details you want to share on the conditions of the tank, setup, substrate, lighting, etc would be awesome.

thanks!

well I have moved this entire system next door, but they are still in the 20l refugium. Old sand and a little rubble. I think he wants it deeper than the 4 in.

bobz

James, how are these guys doing? Any larva yet?

jamescook
02-16-2012, 7:02 PM
grrrrr
no. they have spawned 5 times and he still will not hold past 2 days. I've seen him set down the egg mass, work the hole, pick it up and take care of them. By day 3(today) he has no more eggs.

bobz

Bummer. Just when u think you got this stuff figured out a little some thing like this happens. My male cardinal has stopped holding full term too. No idea why. Hang in there man.

still spawning regularly. He held til day 5 and I could see some eyes developing. I've read they hold 10-15 days? not yet.

I am still pulling for you James! Cool pic... and I'm sure that you will get there.

I didn't know you were breeding gobies! Where were they housed when I was there!

Awesome BTW! Is this the first successful fry?

jamescook
04-27-2012, 8:11 AM
I've got gobies, clowns and cardinals in every tank. The yellow clown gobies and scooter blennies spawn regularly, but I don't mess with them. This watchman goby was my very first fish and has been in all my display tanks. Now the pair is in with the Onyx percs and wc Banggais

hey, starting to plan my tank for a pair of pearly jawfish. I am thinking of a 25G but maybe a 29 would be better so I can put in atleast 5-6" sandbed for them? You think the deeper the sand bed the more likely they are to hold, feeling more secure, etc? a 20H may not have enough floor space. How close is the male's burrow to the female's in your tank? Thinking taller is more better.

jamescook

Bob, mine are in a 20l, so very little water height. They dig constantly and rearrange the sand and their dens. I'm not sure what makes them abort yet. They seem fine with me and their tankmates. Normal behavior, but five days is as long as he's held

bobz
05-16-2012, 12:33 PM
Thanks man..still want to head your way to check out the setup. I may have some time off coming up in a few weeks so i will reach out to you. may have some stuff you can use....

jamescook
05-16-2012, 1:10 PM
he only held a day this time. ***?
Yeah come over sometime. It's always growing. I'm trying to use Bob's stuff I got, but nothing ever just magically fits where I need it to go. BUt I'm reusing a lot of his plumbing par

Well i love these guys, but i have read that it is hard to pair them , so i am going to create me a deep sand bed and house a few a Garden EELS , these creatures are so neat to watch!! Great job on your jaw fish James, they are cool fish to watch. I will have enough problems keeping the eels alive.

bummer. I have not yet made the leap to set up a tank for these guys yet but still want to get to it. The summer is tough with all the travel and work.

Well, they kept spawning and he kept not holding the eggs. I had to move them from their system while I rebooted. Jenny didn't like the bare-bottom tank. RIP
