Need some help from people here

[loohong]

Hi,

Need some information for this 2 type of killi. e.g) Incubation period,
picture...:
1) A.alexandrii
2) S.suzarti

Cannot get much from internet. Hope someone can enlighten me.

Thank You

Best Wishes,

Simp. suzarti take about 3 to 4 months at close to 25°C. Probably take about 4 to 6 weeks at average Singapore temperatures.
Aus. alexandrii is about 2 to 3 months at 25°C if I recall correctly and would take about 4 to 6 weeks at 30°C but such high temperatures are not good for Austrolebias. You will loose many eggs along the way...

How long does Aus. nigripinnis and Simp. picturatus take to develop in Singapore? They shoud be good indicators as the the correct incubation time for the species you mention.

Tyrone, although egg incubation period is strongly influenced by storage temperature, it is my observation for new eggs from overseas, it's best to follow the period when the eggs were collected.

For eggs collected locally in SG, embryol development is more sync'ed to our climate, ie. shorter incubation.

I'm not sure if there's some kind of 'time imprint' within the eggs but the best bet would be Wright's advice; wet only when >90% of the eggs have eyed up.

Wilson, you should take note of that. Update us as you go along.

[TyroneGenade]

My observation is that eggs sent by post from one climate into another warmer one (particularly if they have caught a chill along the way) will develop much faster than normal. Which is why it is VERY IMPORTANT to monitor the development of the eggs; and as Wright suggests: wet when you see the gold of their eyes. Althought this didn't work for Wright and his eggersi.

I bred the Austrolebias nigripinnis for a few generations until I lost them. If memory serves, the incubation period is about 6 to 8 weeks. There were many belly-sliders among my fry so it was difficult to keep the species going. It's a pity as the A. nigripinnis is such a beautiful fish. The women, in particular, love them.

Same here... I eventually over came this by using cool/cold water to hatch the eggs. I then murdered the excellent batch of free swimming fry by missing a couple of water changes...

hi Tyrone,

I have read about the procedure of the cool/cold water hatching method of yours before, but i cannot find the tread....can you provide me with the steps involve again? But cold water cannot last long in singapore...do you have any suggestion on that?

Thank you

I wish Martin Foucade was here so he could tell you the temperature of the water the wild NIG hatch in... I think 10°C is probably too high but I have good sucess with water of about 14°C. I would use some ice to lower the temperature. Another idea is to get a bar fridge and set the temp up so that it hangs about 14°C. then hatch the eggs in the fridge!

Best I can suggest...

[loohong]

Thank you Tyrone,

For forumer in Singapore, where can I get micro worm grindal worm to start my own culture?

Tks

Good luck with Grindals at 30°C! They don't like it much warmer than 25°C and do best around 22°C. Another reason to get a bar fridge. Micros love the heat! In general Austrolebias and Simpsonichthys fry are big enough to take bbs.

Wilson,

I've hatched several batches of Austrolebias nigripinnis eggs without using cold water. Although there were many belly-sliders among the fry, some of the fry were perfectly healthy and I managed to raise them to spawn another generation. I would recommend using ice cubes to bring the temperature down in the hatching trays. I'm not sure about this but if the eggs hatch into healthy fry, chances of them turning into belly-sliders at a later stage are slim. In other words, it's only when the eggs are hatching that you really need the low temperatures.

By the way, if you have never seen a A. nigripinnis before, here's a picture:



It is one of the most beautiful of fish I've seen. When I was selling Killies actively, the women who accompanied the men hobbyists to my house were fascinated by them. They all love this fish.

Hahaha, was just thinking to give the fishes a better diet so I am not sure feeding on bbs alone does help or not.

[TyroneGenade]

I think enriching the bbs with HUFA and spirulina makes bbs an excellent diet. It ceases to be a good general diet once the fry reach about 1 cm in my opinion. Then they need more variation. Frozen cyclops is good. You should probably give the food Tim Addis is advertising a try. The link is:

Grindals can be made very nutrious with gut loading of spirulina flake or peanuts (for HUFAs). Microworm too I suppose if fed a paste of peanut butter and/or spirulina but given that most fish can be tempted to take spirulina flake I don't think there is much point in making the effort.

Hmm...have you thought of starting all over again with Austrolebias nigripinnis? Maybe can find a better way to hatch them in Singapore with your vast experience.

Wilson

[stormhawk]

Wilson, use cold water straight from bottles in the fridge. I mean plain tap water chilled in Coke bottles or something like that. The cool temperature will gradually warm up to our room temperature thereby allowing the young fry to slowly acclimatise to our temperatures.

Nigripinnis males are very aggressive or so I've read. With regards to alexandrii I don't know much but using Google you really can uncover alot of tips and tricks. All you need are the right keywords.

Grindals are very tough to keep in our warm temperatures. Microworms breed like crazy in our temperatures though.

Wilson, my experience with Killies cannot be in any way be described as vast. I have experiences with only a few species and there were many I couldn't breed. If I had known the thing about using cold water to hatch the eggs, I might have got a population going then. I wouldn't mind trying again if I can get my hands on some eggs.

The fish though timid when kept with other fish are aggressive towards its own kind. 2 males will fight each other to the death if separated and put together again.
