When can the fry go into the regular tank?
 
My ten black mollie babies are in their net-safe baby keeper in the 28-gallon tank. They are almost two weeks old and have doubled in size. They are getting cranky in there. 8)

When will they be safe among their mom, a large (male?) dalmation mollie, five glo-light tetras, two zebra danios, two little frogs, a female pineapple swordtail, a Chinese algae eater, and two male guppies?

We have been reading horrific stories of Chinese algae eaters going Postal--so far he's peaceful, but I am most worried about him.

You let them in when they are big enough to not be eaten. About how big are they now? I would say my Platy fry were around 1/2" to 3/4" when they started hanging out with the adults.

If you have enouh hiding spots, you can most likely let them out now.

All of your Livebearers and the CAE will will be the biggest threat to baby mollies.

And you are correct about the CAE. He has the potential to reach 9" in length and can go after other fish. What is your tank size?

I've got a CAE. I kept him in a community when first starting out (he was fine, even with newborn baby fry). He was even kept in a 6ft, very understocked tank, but eventually he grew and become mean. He started to shred my ram's fins, even though he wasn't any bigger than her. So he moved out, and is in his own tank now.

CAE's are funny when they're young, they have lots of personality, but soon he will not work in your tank. I'd recommend getting rid of him before you get more attached!

As for the fry- I say let them out! But it really depends on the individual temperament of your fish. I had 3 guppies and the CAE in a 10G when I was starting out, and the fry took over even though I never separated them. Just make sure you keep the grownups will fed, and that there are hiding spots for your fry. A few of the weak ones may get munched, but most of them will probably survive, and they'll be happier with the extra space.

It can depend also on the other fishes personality. i have 3 swordtail fry around 4-5 months and i was going to put them in a few months ago (into the larger tank) but when i put them in my betta got one of the fry's fin in his mouth and was trying to eat her, so i put them back into the breeder. they were big enough not to be eaten but as i learnt later my betta loves to see if he can eat smaller fish but gives up when he realises that they wont fit :lol: . so i only had the confidence to add them into my 29 now that they are nearly the same size as the others. :D

Some frogs such as albino clawed frog, will make quick work of young fish .

:D If the OP had ACF's, they wouldn't actually HAVE any fish left in the tank. Mine go after my fingers and the gravel siphon.
