Hi all,
Recieved a bag of 70 eggs of Simp. Magnificus from Mr Au and managed to hatch about 20 of them. From what I saw, only 1 fry died.
I wet them for about 5hrs and dried up the peat to be ready for the next wetting.
However, I noticed, most of them seems to have a curved-up spine. But, I can't confirm til when they grow bigger and show more visible symptoms.
As for the next wetting, when is the appropriate time to wet them again?
Fed them with live BBS and seems that they are not feeding on them. So, I added 1 drop of liquifry.
Thanks alot Mr. Au
Are they free swimming? You can wet the peat again in 2 weeks' time. What you can do now is to isolate maybe 5 fry per small container with some moss. Feed accordingly. This will increase their survival rate. I tried this method, it worked for me. But if they can't swim, it will be toughOriginally Posted by rubripinnis

What is your water source, PH, GH and temperature?
They like to lie on the bottom of the container. However, they can swim up and down when they sense movement in the water.Are they free swimming? You can wet the peat again in 2 weeks' time.

pH is 7.2, kH is 1 and temperature is around 27-28 degrees
Curved spines suggest malformed fry. I normally associate this with fry hatched from old eggs... or rather eggs that should of been hatched sooner. These fry rarely if ever swim and remain belly-sliders. Most will die. Eggs that hatch to soon yield fry with visible yolk sacs and also don't swim as they should but some eventually do start swimming.
Keep an eye on the peat. Check it to see how many eggs are still left. When you see a fair number of eyed-up eggs then wet half the peat and see how good a hatch you get. If the hatch is good (swimming vs belly-slider fry) then wet the rest.

Hi Kee Hoe,
It may not be curved spline. From many fry that I had observed, the body is straight but tail pointing downward. Is it what you observed? When fry grows bigger, it will be straight then.

Hi Poh San, Garrett here. I think you got the wrong person
Yes, the description you gave suits perfectly well from what I observed too. The tail is pointing downwards and the spine is somewhat swollen or bulging.
I will continue observing them and when they grow bigger I will update you guys.
Hi Tyrone,
When I dried the peat for future wetting, I already seen some eggs eyed-up. Does that mean I should wet the peat again ASAP or should I wait for another week or so?
Hmmm...have you ever tried taking one batch of eggs, seperating them out, and wetting one too early, another on time, and yet another to late?
Thanks! I just found out from a rather unnerving experience that clear eggs can survive underwater even after some time in peat incubation.
Define "on time."wetting ... another on time...
Should I have enough tank space and suitable eggs I will perform your experiment. In the past with red eggersi I have wet portions of peat at different intervals and seen no improvement in the quality of the hatch. This went on for 3 months and the eggs were already 4 months old at the beginning. Too old?
We kilomberoensis eggs too soon and you als just get belly-sliders.
From my experiance, annuals hatch when they are good and ready unless we stupidly intefer. If you see eyed-up eggs, wait 2 weeks and then wet some of them and see what happens. SAAs almost always give a better hatch 2nd time around.

This morning I woke up, I found all my fries died!
Anyone has any idea why they died so suddenly? The night before, I saw them they were swimming healthily but they just died overnight.
I fed them Liquifry in the morning and BBS in the afternoon. Cant be that they starved to death. As for water conditions, I removed several dead fries and did not do any water change.
I suspect it is the water condition which kills them. Any dead bbs will foul the water quickly if not removed. The fry does not eat the Liquidfry but it is used to feed the infusoria which the fry eat. Again, too much and it fouls the water.
Water changes can also affect the frys. What you should have done is start with about a cm or so of water. Every few days topped up the water - this will have the effect of doing water changes. Siphoned out any dead bbs. Put in some snails to help clear any uneaten food and also snail poo will also help to generate infusoria. Put in lots of java moss in the container also. Helps with the water quality.

Hm, damn. Didn't know that they were so prone to bad water conditions.
Actually, I didn't experience any deaths for my AUS fries even when I followed what I did for the Sims. Magnificus.
Very sad actually after this incident, but I managed to learn something from here.
Now waiting for another week to rewet my peat again. Hope that there will still be fries hatched
Magnificus fry aren't exactly as tough as their AUS cousins. They are prone to deteriorating water conditions and will die suddenly as you have found. One time they're happily swimming, the next time they're all dead.
If the fry keep hugging the bottom, that's not a good sign. They should be out and about looking for food. Observations of my own from watching some of my fry during feeding time are as follows:
1) They are highly attracted to moving food, not immobile food like Liquifry..
2) The fry usually "lock-on" to a moving food item, for example microworms or small daphnia.
3) Before they feed on the item, if you look closely they will show their mouths slowly open before engulfing the food item.
4) At times the fry will adopt a curling body before uncurling at a quick speed to lunge at the prey. I don't know why they have this habit.
Never overfeed the fry. Sometimes feeding them the wrong size of food is also a killer. Young Simp. fry usually need infusoria as a first food before moving on to microworms. They will only feed on BBS when they're slightly older but this is species dependent. Simp. flammeus fry are able to handle newly hatched BBS and fresh daphnia. Depending on the size of the fry, they may look big but have small mouths.
If you get fry again, put them in a container with aged water and some java moss and a snail or two. The more the merrier. A few drops of Liquifry should have been added to the water a few days beforehand to generate infusoria. When the fry do hatch, transfer them ONLY when they are fully free-swimming. When transferred too early the fry will not adapt and die quickly in the new tray. Use a plastic soup spoon for this purpose. Turkey basters can be pretty rough for newborn Simp. fry.
The fry should grow quite quick the first few days as they feed on infusoria in the water. They should appear like tiny white specks when you use a torchlight and shine in. Observe the fry as they lunge after the infusoria and feed on them. You can see it quite clearly. About 2 days afterwards you can add in a small drop of microworms and I mean SMALL. Too much microworms can die off and foul up the water, even with snails that are scavenging.
Before you try and feed them with bigger foods, drop in some BBS or daphnia and see if the fry actually ingest them. Their bellies should turn orange if they're feeding on the BBS or a little greyish if its daphnia. From then on they will grow quite fast on a mixed diet of BBS and daphnia. At this point, microworms can still be fed but in small amounts as always. Usually the fry ignore these once they feed on larger prey.
Good luck the second time round.

From what I observed for my Simp. Magnificus, I noticed that they were hugging the bottom most of the time. They don't look interested in hunting for food. This sign has already got me worried and I suspected that maybe, BBS were too big for them.
However, I noticed that most of the BBS were gone after an hour or so when I feed them. So, I left out the case of starving.
As for them dwelling on the bottom and not moving, I don't know what's the cause of it still.
BTW, what are the percentage of having fries on my 2nd wetting?
I haven't raised killifish eggs to eyeing up stage yet but you could base on time either on estimated incubation period or how ready the fry appear.
After 2nd Week,
3 fries hatched, 2 died. Leaving 1 sole survivor.
Checked the peat. No more visible eggs, waiting for another 2 more weeks before I wet the peat again.
Any chances that the 3rd wetting will produce fries since I don't see anymore eggs in the peat?
Hi Garrett,
It is possible to do a 3rd wetting as some eggs can be coated with peat. Sometimes we tend to overlook some eggs as they can be as dark as the peat. It is still worth a try.

Hi Jianyang,
Ok, point noted. Usually, how many times do you guys wet the peat? 3-4 times? or do you keep wetting until no more fries is hatched?
Usually by the 3rd time there isn't any eggs left but it comes as no surprise as some people have hatched fry from peat that have been left in storage for more than a year. Such things have happened before and these are usually the resting eggs that have taken a longer time to fully develop.
