Hello!
About a week ago I purchased 25 pseudomugil gertrudae eggs to hatch out. They've been in a jar with aged tap water and a few drops of methylene blue for that time and today I have a couple of fry! This is all good but I wasn't expecting any for a few more days!

So far I have two fry who are swimming about. I have some jars which I've been growing infusoria in in the garden. My question is what should I do with the fry? Should I move them onto a bigger container now or should I leave them in the jar they're in and wait for the others to hatch out? Also, I was intending to buy some moss for them to act as cover but the shops will all be closed by now. Would a few tops of cabomba be efficient for a bit and should I add some into their jar now?

Thank you!
 
Move them to a larger container as soon as you can; add the others as they hatch.
 
Yes, live plants will always help so adding some cabomba would be good.
 
Also, daily water changes, if they're in an unfiltered container; fry produce more ammonia than an adult fish of the same size would.
 
Best of luck!
 
Those are some tiny fry. Most fish are born with a yolk sac which provides them all their nutritional needs until it is absorbed. They will not eat until it is. You have the right food for them. Bear in mind that container size matters in terms of the ease of finding food.
 
I can not guess how you would remove fry and not eggs. All my experiences with small bow fry (gerts, furcatus and threadfins) were from live fish. The first two I saw nothing until I saw free swimming fry. Threadfins were an accidental spawn in a temporary home I gave them in a bn fry tank. I could not get infusoria or a safe space organized, so the fry soon were gone.
 
You do not have to worry about predation. So I would assume a small tank- like a 2.5 gal., with an air driven fined pored sponge filter and small heater should work fine. Any plants help- I discovered the threadfin fry hiding in floating stem plants I was taking out of the tank to clean it. Infusoria and plant cover would be the ticket.
 
You might want to wait for somebody more experienced on this to weigh in. I do know any tank with plants should have infusoria as well. This was why my surprise pseudomugil fry lived, I am sure.
 
Thank you both for your help! I have a small container prepared with aged tap water already, though I'm not 100% sure how much water it holds. It's 15cm long, 10cm wide and I have the water at 3cm deep. Does that sound okay?
I can add some cabomba which is from a larger tank of mine - should I wash it first or can it be added straight away?
As for moving them, my mum has a few spoons used to measure out liquids which are quite deep so would these be suitable?

One of them is quite light in colour and swimming around fine and the other is darker and sits on the bottom sometimes. Should I be concerned about this?
Sorry for all the questions!!
 
Just to ensure they can find food when I do put some in. If they're all managing to eat it okay then I can raise it to 5cm instead :)
