Pink carnation spawn


Recommended Posts

This is the set up. You can see a big jar in there. I didn't want to move Bitsy for conditioning as figured she wouldn't like it much, also wanted her to be in something nice and roomy so I put her in that jar which I covered in aquarium backing that could be easily lifted up once per day. It worked well except for the fact that the jar is still in there! Too disturbing to take it out post spawning so I'll leave it until the fry are big. Had a thermometer in the jar as wasn't sure how well glass would conduct heat. It worked just fine, same temp in and out.

Tank has java moss, 3x java fern on a rock, 2x anubias on driftwood (fry like hiding in cavities of the wood as well as in the java moss), 2x IAL, terrecota pot, sponge filter, heater and I put bubble wrap, a plastic lid and a bit of polystyrine. The later was chosen for nest construction. Oh yeah and duck weed <_< grrr lol :P For anyone who hasn't read my other posts it made it really hard to see the tails as they were identical. Fry love it though!

This pic would be really good if my finger hadn't reflected in the glass <_< anyone skilled at photoshopping? I'm stone age :P lol

Fabian admiring his handiwork :P He seemed to prod her after a while and she'd 'come back to life'?

Taking a break from egg eating! <_< Looks pretty exhausted...

Thanks Sarah :) I've set up Goliath and Nariyani (guns n roses) for conditioning in a small tank. Maybe too small but growing impatient with fry growth rate in the spawn tank :blush: Anyway, I believe that try as i might duckweed hitched a ride on java moss <_< lol

Looking at me! She turned her head to see what I was up to, flaming paparratzi! :P

Two days since free swimming. Unfortunately I couldn't get very good pics. Large tank (2.5ft), brown water, not many fry and waaayyy too many hiding spots! Here you go anyway, just to complete this little story in pictures :D

167401_10150115482043594_693283593_74840

and now three weeks old and contemplating grindles :D Not sure if they're too small for grindles, seem to eat them though. I'm still giving BBS for the two runts that are one week old size wise! HUGE size differences in fry!

Oh good :D Well its certainly great to have people around who's eyes don't glaze over every time I try to show them/tell them about my fish :P lol

Ok last few for now

lol you'll have to join the 'being patient' party and wait for the little buggers to grow a bit so I have something more to take pics of :P

OMG I think there are 9! :dance: I thought only 7. Three are TINY, one of those 3 particularly, its hiding in the dirft wood so I put some BBS there for it especially because I think its scared :blush: I don't blame it with the size of the others! just a little speck like some of them were when they were first free swimming, though a more physically developed speck :P The big ones are big enough for grindles, just!

What causes such huge differences in size? I'm thinking genetics but also I've observed the big ones chasing the little ones away from the food so I suppose thats there too. I wonder if some could be late hatchers? Fabian wouldn't have been there to clean them though.

Great pictures Fishish. There is no such thing as too many photos! :P

I'm pretty sure the larger fry release a hormone that stops the smaller ones growing. Makes sense if they are in the wild, but just a pain in the tank. <_<

Mine still have that variation. Most are in jars now but small ones still small??? Have heard somewhere that these grow into the best fish but waiting to see that for myself. I only got 14 out of my first attempt but over 70 easily this time. Good luck with the babies.

Betty Splendens -

The explanations for this are far from simple. Scientific studies have proven that most fish, including bettas, excrete a hormone that acts as an inhibitor to growth. In the betta community it has widely been said that this growth hormone stifles the potential of smaller fish in the spawn, giving the advantage to the larger, healthier fry. While this goes a long way to explaining the sometimes dramatic size differences between fry from the same spawn, it is my personal belief based on what I have read that this hormone actually works to limit the growth of the fish so that it does not outgrow its environment. In nature this would be a handy tool, ensuring that there is enough space and resources for all. In the spawn tank, it's just inconvenient. A couple of hundred young fish in a ten gallon tank will soon produce enough hormone to severely limit growth unless the water is changed, and changed often. I change the water in my growout tanks at least 50% every single day. Other successful breeders have reported changing as much as 80-100% per day, with excellent results.

Maybe Stefan will see this and post a really informative link (that was a compliment, you are smart, I'm not flaming you, promise. :) ).

Good luck with these guys though!

Thanks for linking that Sarah. Sounds a little bit speculative. Have to say though, it's proving difficult to make sense of extreme size differences otherwise!

@ delyall, if I can get them to spawn!!! Been conditioning over a week now and Goliath has not built a nest! He never has, in his old tank either. I was thinking they may be difficult, Goliath is a wimpy fish :P lol (oh but i secretly love wimpy males in general ;) ehehe ) he flares at a mirror for a few secs then hides <_< However it was looking hopeful, they initially appeared to respond well to each other and Goliath immediately began blowing bubbles at first glance at Nariyani. Alas, he blew a few that one time and that was it! What to do?? :confused:

Sunnylass I'm glad you enjoyed the pics :) I have a few more now :D

Four weeks old.

Red has begun appearing on caudal and anal of larger fry. They also have ventrals :dance:

166315_10150118960383594_693283593_75565

You can see some white on the anal, also on the pectorals of some. It looks more 'ruffly'/'combed' than my camera will capture so i guess its the cambodian coming through?

163719_10150118960358594_693283593_75565

Two medium sized fry snacking on a shower of BBS. And yes, that is a chase coming on! They're doing the slow approach then charge thing with rapidly increasing zest! Sometimes, if well matched they look like they both charge, bang heads, then calmly swim off in opposite directions. Its quite funny! lol

162995_10150118960238594_693283593_75565

This is Tiny, the smallest fry (I think! thought there was one runt but there may be 3!)

163658_10150118961213594_693283593_75565

My so far best attempt to capture Tiny and one of the biggest fry side by side :blush: They were pretty close to each other so not a bad shot for a reasonable idea of size difference

Hey Fishish, how are they now?

Just curious, when the time comes, would you be willing to ship to Sydney? My parents got me the first Pink Carnation pair, but the female died before spawning. :(

Oops! lol hey Sarah... bit of a belated reply here :blush: well I don't have many, only eight and only three of those are big. So not many to choose from and I may end up keeping most... perhaps if I spawn Bitsy and Fabian again?

That leads me to a question I have for you all, now that they are jarred will the runts grow? They don't seem to be growing and are still the size of.... aprox seven week old fry <_< I'm not sure what to do?

I need some help with sexing if anyone feel so inclined? Have read some info about it including the Ausaqua article and felt confident but then I tried to actually sex them and well... :blink: lol

The gang: 196903_10150168496863594_693283593_81503 Yeah I know they're too big to be loose in the tank together. Not sure if anyone remembers, I had an operation in december. Had some post surgery complications so back to hospital and this is what I came home to! lol but they were ALIVE :D Except for the one second from the right :(

Female??? I've tried to shine a torch at them to 'spot the ovary' but can't see anything... possible hazard of the untrained eye? :blush: short ventrals, a bit of a belly and very timid.... nice colour but I think the body shape is not great?? has a bit of a dip in the head- mild spinal defect? That seems to be inherited from Fabian (dad) but is even more evident in this fry. She/he is a bit 'bottom heavy' when she/he swims ie swim,stop,bottom/caudal drops

196903_10150168496868594_693283593_81503

196903_10150168496873594_693283593_81503

Male? long ventrals as relative to the others, can't see any ovipositor as I can on the other two photographed here.

196903_10150168496883594_693283593_81503

Female? bit of a belly.196903_10150168496888594_693283593_81503

Perhaps a bit late now but I'm also wondering about fin length. I believe the length of fins and fin form can depend on how they're raised? What does such raising involve? I have my assumptions but yeah assumptions :P

I'd have to guess that these look like girls. They are from a long fin spawn - correct? Having had an all female spawn and being so confused for so long, I tend now to assume that they are all girls unless sprouting into a boy occurs lol. Unless it's a PK spawn... Then I'm clueless!
