So Whose Managed To Breed Galaxy Rasbora Then?

[Miss Wiggle]

and how did you go about it?

now mine have been settled a month or two the behavior seems to be changing, we're not sure but i suspect they are preparing to start spawning. i feel like i really *should* try and breed them and raise the fry if they seem to want to, can easily sell them to the lfs, just not got much room for breeding really.

now while i'm not a novice fishkeeper i've bred very little just your basic livebearers really, i've never had room for grow out space so thought it's crueler to breed them and not have room for them properly than it is to just leave it all up to nature. so i do need beginners advise on breeding really!

got 5 of them in a 10g tank (no other inhabitants) so there should be room to raise some fry in there to a reasonable size, however it'd mean wrecking my lovely minimal aquascape i've been working on as there's not really enough hiding places and nowhere for them to lay they're eggs.

i've also got a trickle filter which would probably destroy any plants i could use as a spawning mop and there's a small powerhead which would be too much flow for the fry, so i was thinking of getting a basic sponge filter in there and letting it seed for a couple of weeks, then turning the trickle filter and powerhead off, putting a spawning mop in and seeing what they do.

questions
- how many fish should you expect to raise from one spawning
- what did you use for a spawning mop, i'd like to use real plants if any of the floating ones would be any good
- are the parents likely to eat the fry, i doubt if i'd be able to seperate them although i could provide many hiding places and just then leave it down to natural selection and have a small number survive..... or is that just hoping too much and they'd all get eaten

i'll probably think of more but that'll do now!

i have not bred them yet, not many people have. Apparently they are similar to egg scatterers .. they think.

The best info I can give you is from the study which named them. Not sure if you have this link yet.. I've posted it on a few other threads.

The only other thing to do is probaly harrass Mike Clarke from PFK to plead with the guys from Bolton Museum to write an article detailing how they managed to breed them

I'm was going to quote an excerp from the journal, but cut/paste is prohibited in the document.

Try converting it with an online converter

Might take a few mins as the site the PDF is on is quite slow.

i've got adobe, it just opens a new window, thinks about it for 5 minutes then the status bar say's done and it's a blank page?!

I would think the best option would be to look up info. on breeding its closest relatives (as suggested in that study)...
So Microrasbora/Danio erythromicron and Microrasbora rubescens.

Here are a couple of links:
http/www.stroodaquarist.co.uk/content/fa...factsheet17.asp
http/www.practicalfishkeeping.co.uk/pfk/...m.php?news=1210
You should be able to find more on google.

I think, in reply to your questions, that you're not going to be able to raise them with the adults. They don't produce all that many eggs to begin with and they take a while to hatch. I doubt any would survive. The number of eggs is suggested by PFK to be around 30 - so I suppose you can expect most of these to survive in ideal conditions. Chances are you'll get far fewer - at least the first time. Using real plants for spawning should be fine - but it'll be harder to remove the eggs (if that's what you decide to do). I personally would just set up another tank for the adults and move them - the fry are more likely to find food etc in an establishd, planted tank.

fair enough, thanks for the info i'll do some more reading

it's pretty unlikley that i can set up another tank for the fry or the adults so if it means i can't breed them then so be it. not particularly a case of me wanting to breed them more than they seem to want to and with the current situation with the population in the wild the more tank bred specimins we can get into the shops the better.

I've uploaded the article to a server in case anyone else cannot download it. Hope fully it works.

my tank is just going to have java moss in with abit of riccia floating on the surface as i emagine thats where the fry will hang out

java moss is an easy growing plant from what ive heard so should tolerate lower lingting levels and ive heard many people saying about them breeding in java moss

i think youve got plenty of room in your tank as i have 12 in a 14 gallon tank and theres plenty of room

i will be leaving the eggs in there as the moss will be attached to the bog wood so as soon as i see fish i will hunt as many as possible down and transfere them into another tank on there own

good luck

miss wiggle.. I think if you attempted a carpet of java moss or something similar, and planted the tank well you could provide the fry enough space to hide in. Its better than giving up before you start

I'm going the low light heavy planted route to try and observe behaviour. I do have the PFK 25litre tank on standby if I need to go there though

i have a 2 foot tank heavily planted with only 8 galaxys in it. i have just seen 1 fry swimming around but it looks blue like a cardinal?
i havent had cardinls for 6 months and havent bought any plants, have not even given it a water cahnge for a couple of weeks
the littl fry is prob 6mm long and quite slim in the body. it just came out when i did a top up from some evaoporation.

any ideas?

hmm..

wait 2 months and see

look for a twinkle in the celestials eye

get a super snappy zoom camera

write a book on a tank based spontaneous erruptions of life

hmm... common things happen commonly, so would guess its a celestial fry, but time will tell.

hope you dont mind me bein a bit crazy .. i'm overtired and need bed.. nn all!!

Educated guess--> as for color.. my celestials were a pale blue colour when introduced into the tank.. it took rest and nice live foods to bring the red colour out.. maybe its the same with fry.

edit: my sleep adled brain has had an idea!!! I've read that some guys have bred them on the forum. It would be nice if one of them could post their experiences and we could get it stickied. That way we could have a rapid sharing of experience to allow up to breed these guys back at speed and in good numbers!

the link Maximumbob posted has a great picture of these and you can see they are actuly blue and not black
