Chrysiptera parasema - Yellow Tail Damsel

Chrysiptera parasema - Yellow Tail Damsel

Postby Luis A M » Thu Nov 13, 2008 11:47 pm

YTD is the ideal species to experiment breeding techniques.A pair can be kept in a ten gal tank,provided with a small flowerpot or cuts of PVC pipe where the fish will readily spawn.Additional pipes in the opposite side of the tank must be provided where the female could find some cover while the male is brooding.
This is a 5th night old spawn,when hatching is due:

and a closer view.Eggs are 1.23 x 0.74 mm.

These are different views of a newly hatched larva,of 3.7 mm.

Luis, GREAT images! So, how do you go about pairing them up?

recently i got to have a look at a 280 gallon system that had 6 yellow tail damsels. 5 damsels were the same size, and the 6th was smaller. i found one of the larger damsels tending to a nest, so i assume all 5 of the larger yellow tail damsels were females, while the smaller one was the male.

the owner of the tank described behavior that would support this.


are yellow tailed damsels possible to raise on S rotifers?

I think you have it backwards. Unlike clown fish for Chrysiptera damsels it is the male that is the larger/dominant fish. But similar to clownfish the male is the one who tends the nest.

Your observations fit this exactly, but you drew the wrong conclusion I believe. The larger fish were males and the smaller one is a female.

Hmm. Witt does cite 3 Chrysiptera species as all being Protogynous. He also writes "Males are always larger than females; however, the overalll small size of these species makes using size to tell them apart less than a sure thing."

Pairing damsels is always a risky game.The concept of pair is different than for clowns or gobies.A damsel pair means only that the male tolerates half heartedly the female,chasing her a bit but not killing her.As William says,the male is always the larger, dominant member of the pair.YTD are small and mild mannered,as damsels go,so you can expect less losses in the mating process.
You can put a possible pair or a small group and see how things develop,being ready to put a tank partition or remove a fish that has thrown the towel.
Frequently this process took place in the LFS tank and you find the two survivors,two conspecific damsels in the same tank,without much fin damage.These are always a mated pair. :wink:
I can´t think of damsels being sequential hermaphrodites,but if they were,they have to be protogynous,unlike clowns.
Witt says it has been proved in some few species,like Dascyllus. :?

thank you for the correction. sucks to be the lone female in that tank with 5 males.

Iam raising some few larvae of different ages.A large one 16 days old is pre-meta.Getting darker and staying close to the wall,picking at some harps.No matter what they tell you,it´s hard to see a dark larva in a BRT! :wink:

META TIME!!! :D :) :o :shock: 8) :lol:
It is not the first time,but it feels like if it was! :twisted:
It is so great to suddenly find a deep blue little fish against the dark BRT background! 8)
This fish is 21 days old,but it possible settled 1-2 days before.
So this different protocol works for damsels.S rots+ Moina-NAN-closed circulation.With something in common with my previous successful runs;completely bs less. :wink:

Pics of the post meta.The blue colour was more intense when the fish was free in the tank.But the yellow area is well defined,which marks that meta is finished.

Image

Against a light background,the blue and yellow pigment spots are easier to see:

The juv measures 9 mm,TL.:

Blue colour is stronger in the dorsal area:

i have been trying to get my YTDs to spawn, is there anything I can do to trigger this, types of foods, conditions, light cycle, water movement, etc...
always use the right tool for the job......A REALLY BIG HAMMER!!!!

New run using the same protocol as in: viewtopic.php?f=141&t=5330&p=52499#p52499

Again,three larvae survived.First meta today at 31 days. 8)

And one died today :( But not the one going meta but the smaller one,of 6mm TL.
So not a clear DOA case...
If you want to make $$$$,don´t raise damsels! :wink:

In a sample of the sediments,I saw some rots,nematodes and interestingly some adult A.tonsa with ared material within.The only source for this pigment could have been the NatuRose enriched food,so these calanoids could scavenge somehow... :?
The fish undergoing meta,still a washed pale blue,moved to the bottom and stays very close to the airstone.Which seems a very different post meta behaviour that the one recently shown by C.hemicyanea,no matter the closeness of both species :?

It was just temporary.Most of the time both fish race at full speed around the BRT.For some reason,this merry-go-round goes always counter clock wise :? .

The other has just settled,so meta time goes anywhere from 20-40 days.

I moved them to the comunity grow out tank and took some pics.The juvs are tiny,though gorgeous! 8) Or at least this is what I think of them :wink:

hi this is my pair laying eggs today
http://www.youtube.com/watch?v=2-wu3c0Zlq4
but i always have a pair by putting 2 fishes togheter so i think they will be protogynus
so you breed them initially with rotifers?

luis what are your future plans for spawning them? This is one of my favorite Damsels. I will be adding some shortly. I am going to get about six, grow them and try to pair a couple off.

The hybrids are beautiful. Are they 'easier' to rear? I am wondering if heterosis kicks in .

The YTD is my first choice in the family.

Not currently.Hybrids were just the same as pure species regarding raising.I have not seen nor expect any heterosis issues.Both species seem indeed very next of kin.
