I unexpectedly got some Nothobranchius rachovi eggs yesterday.

I have never had any experience with killifish so this was most definately a first for me, I did LOTS and LOTS of Quick reading , before deciding after looking at the eggs that they appeared to have the Black spot, and so put them in a container in the tank and covered with water....
Within minutes there were babies , I cant believe it nature never fails to amaze me :blink:
Anyhow, at the moment, i have 15 babies which I have seperated into a seperate holder ( lots of wasted icde cream!!! :hyper: ) in the same tank.

I wondered , just a couple of questions,
I was not expecting the babies so quickly and am currently feeding on Liquifry no 1 as it is all i had readily available,,,, Will they be ok with this short term, until I can get to the bottom of the Infusoria threads !!! I have lots of micro worm which hopefully from what i read they will take after about day 3 ???
Secondly, How long do I wait before Drying the peat back out, there are varying answers, I was planning on 3 days is this ok ??
Third question .... I am a pain (am a woman!! LOL) where is the best place to get more of these eggs / different species I LOVE them already and find them so facinating...

Many thanks
Becks. x.x.x.

Thats fine

Get some brineshrimp on the go as well.
Live floating plant such as Salvinia natans and Liquifri No1 will speed up infusoria/parmiceum levels. but keep the tubs clean.

Take it slow Becks, deal with what you have in front of you first, your not home and dry yet from a rearing standpoint. Learn about your charges then move on. Concentrate on these if thats what your interested in.
N. rachovi are one of the harder Nothos for the novice due to the small fry and feeding problems that go along with this.
If you wish to stick with Nothos seek out n. guentheri and palmquvisti which are much easier.

See here for more N rachovi info. Its from another thread I answered and it may well serve as relevant to you.

The species in question is not from Thailand but rather from around Mozambique, Africa and is a true annual.
You sure have picked a hard member of the Genus to start with. Anyway with that said I will attempt to tell you how to raise this species.
From my own dealings with the species in question N. rachovi Beira 98. I lost quite a few batches of fry in the early days mostly through ignorance and stupidity, nowdays they are a doddle.
OK you will recieve the eggs in peat, on the bag there should be both a spawning date and a prospective hatching date. Rachovi eggs can take anywhere from 4-6 months to hatch as they go through different development stages whilst in the peat (diapause) As I said earlier they are true annuals, meaning that they lay their eggs in the bottom of the pool they are living in, the hot summer sun dries up the pools but the eggs remain viable until the raining season returns. During this time there may be a freak storm and some of the eggs will hatch and the pond will dry out once again, these fish fry will obviously die, but there will still be eggs in the mud, as not all will hatch at the same time which is natures way of preserving the species.
Ok when you get the eggs and have assertained a hatching date (if he's selling them, then I would expect that they are pretty close to hatching, maybe no more than a few weeks). First off I would check the peat for eggs, These will be difficult to spot amongst the peat at first, but should be amberish in colour. You should really get yourself a good magnifying glass from your local chemist or opticians. Looking through this at an egg you should be able to see the developing embryo, now the way I can tell if they are ready to hatch is look at the eye, around the iris (black part) you should be able to see a gold coloured, kind of ring. If that is present then they are ready or at least some will be ready. If you dont see this then I would personally place the peat in a clean fish bag, keep a little bit of air in the bag and tie the opening with a knot. Store in the dark at a nice warm constant temperature (hot press/ airing cupboard wraped in a blanket) anything where it is warm. The inside of the bag will condensate, thats fine. Check again for good signs of development as above in say a fortnight.
Phew!
If the eggs are ripe enough to hatch place you peat in a 1lb white (for visual purposes) ice-cream tub. float this in an aquarium and cover the peat in the tub with about 30mm of tank water of around 75'F. Some of the eggs will hatch almost immediately. The fry are really, really small, you wont believe how small these things are compared to guppy, platy young.
Right get another good size white margarine tub prepared and try to catch the fry using a syringe with a littl piece of airline attached carefully suck up the fry one by one and place in the new tub which incidentally should also contain the same depth of water from the same source.
The fry must be fed immediately. Given the size of these, the food stuff has to be very small indeed newly hatched brineshrimp are too large. Infusoria is the order of the day (see my pinned topic in the killifish section) Place some Salvinia natans or similar in the fry tub this will also provide some natural infusoria and place one drop of liquifry No1 for egglayers in there as well. Keep the fry tub spotlessly clean and add some extra water day by day as you go along (a few mm per day) After 2-3 days the fry can be offered newly hatched brineshrimp and you fears shold be almost over. Cleanliness is paramount with these, remove any uneaten food soon after feeding. Feed the fry 4 times per day, little and often. Also its a good idea to mix a few grains of cooking salt in the water to prevent velvet. Just a few grains mind.
Notho fry grow quickly with regular food and small waterchanges, they have to as their whole lifecycle only lasts 10-15 months.
Now your peat. All the fry that were going to hatch will have hatched in 2-3 days. Take your peat squeese the excess water out and lay it on a piece of kitchen towel. get its consistancy to something like pipe tobacco not too dry and not too wet. Rebag and store this as before for another fortnight. then repeat this process all over again. You may find that you have a higher hatch rate from your second wetting than the first. You can repeat this procedure 3-4 times if you like. I would normally have enough fry after 3.
N. rachovi fry grow quick as I said earlier, you may find you have skewed sex ratios in favour of males or vice versa. (par for the course) seperate the sexes as they become apparent also seperate according to size as Rachovi males are quite aggressive toward on another.
Now N. rachovi will rarely take dried foodstuffs, but I have had them take frozen bloodworm etc in the past. If you can make provisions for giving them live food then do so.
Culture you own (see pinned topic again in killifish section)
Starter cultures available from various sources on the net
Whiteworm, Grindalworm and Microworm. Fruitfly if you like but can be a bit awkward for some people.
I think I've covered just about everything there may be some holes here and there if so don't hesitate to ask if you have any problems.

Thanks BigC ... you are fab LOL :blush:

I am going to see how it goes, i have some brine shrimp on the go and fairy shrimp should be ready by tommorow hopefully , fingers crossed.
I now have 22 babies, every time I go to the tank there seems to be more.
I know I am not home and dry yet, and just hope that I suceed with them, if not i will be dissapointed, but learn by any mistakes.
The question regarding other species, is so that I can research, I normally do with any fish WELL in advance, but these were unexpected, I will do the best I can with them, for now they seem to be doing very well

Again thankyou for your reply

Thankyou, I will see if i am off work and possibly have a ride up there
They are all still ok this morning :wub:
 
so how are they doing?? :)


Sorry Shelagh been on a course for past week, nice hot sticky office ewww ..
Anyhows, the fish are still ok , think i will need to transfer them soon from their tupperware dish .. gonna have a big fishy sorting night so will hopefully update soon

Been through that stage, mine usually took days though.

Half way through and knackered !!!!!!!!!!!!!!!! Well still half the night to go ...
Hmm, the baby fishes are not loooking too good , seem to have lost about half of them :grr: . I am trying to clean the tupperware out for the others but they dolnt seem to be growing much ,,,, Will keep you updated

Rachovi are notoriously hard to rear in the first few days after that it should be plain sailing.
After infusoria you should be feeding Newlyhatched brineshrimp predominatly. Vinegar eels also to a certain extent. By newly hatched brineshrimp I mean exactly that as one and two day old shrimp will have doubled or tripled in size and lost some nutritional value. So they are too large for N. rachovi fry to consume.
When I first encountered this species I lost batches of fry. The first two batches I ever hatched amounting to hundreds were lost. Nothing worse than seeing you labours amount to nothing in this way.
Nowdays I like to use floating plants in the fry tubs with light over them floated in the main aquarium (natural infusoria) Keep offering the NHBS and keep things clean. Use an airline in one corner with around 1 bubble per second.

Well its nearly 24hrs later , and nearly done !!! LMAO
As for the babies , hmm, feeling a bit disheartened there are just 5 left ... I have put them in a new container and added an airstone as suggested.
I am having a little trouble getting the BBS going, but have had a few in their (are BBS smaller than microworm ?? i have added some of that too and they dont seem to have touched it)
I have done my best with them , prob was I have been at work on a course so not had as much time as normal to continually clean etc etc , so i think if i try with killi's again , will a) prob choose an easier one to raise and b) start them when i have more time
Anyhows, I hope the remaining 5 will survive
I have saved the remaining peat , wet slightly and put in a dark place so I will try with it again in another couple of weeks and hopefully be more prepared

Thanks BigC for all your help and suggestions

No probs Becks, Dont let this set back put you off, You are now certainly wiser from your encounter with this beautiful species.
Nothing comes cheaply, The old addage springs to mind....You only get out of something by what you put in.
This species is hard in the early days but the colours are fasinating when you accomplish it.
Wetting the peat again in a couple of weeks may well contain a bigger hatch than the first so prepare well. Get everything sorted and organise yourself to be able to be on hand should anything go wrong. Try also placeing a few grains of Cooking Salt not Table Salt (helps against Velvet) in a corner of the fry tub (only a few grains mind)
I have personally reared species of killifish whereby I had only 3 fish, they being rare, I had to persevere so as I had, at least, some sembalence of a future breeding program.....so dont be disheartened.

BigC
 
Update ...
I only have 2 left the others all died.... I think I learnt a lot tho and wont let this put me off ... Indeed I have some others on "order" and think that they are an easier species to rear .... Cant remember the name of them tho will have to find out ...
The two that are left dont seem to be doing all that well, they have grown but only slightly ,,, I have put an airstone in on a gentle feed, and have now resorted to feeding liquifry no 2 they seem to be doing better with that than the bbs ... but then hey ho ... anything can happen

This story echos of so many people ( and I must confess I was no different) wishing to keep and breed killifish, sometimes when starting with fish but majority of the time starting with eggs.
Speaking from experience, Nothobranchius rachovi are difficult to rear especially over the first 3-4 weeks, once over that they seem to be fine.
Becky, if I were you, and you are looking to keep and breed Nothobranchius sp. then choose Guentheri or Palmqvisti.

N.guentheri Zanzibar 97/2

NpalPanganiTZ94-7_2.jpg

N. palmqvisti Pangani TZ94/7

These although not as colourful as Rachovi will give you more chance of sucess as the eggs and resulting fry are much larger (can accept newly hatched brineshrimp from the word go) The also have a much shorter incubation time.
