I know this has been asked before and I tried finding it but couldnt.
How big or old should guppy fry be before you put them back in with other fish.
If I remember right about an inch but want to make sure before I let these three babies go.

Good question. it depends what other fish you have, however, almost always! The fry must be bigger than the mouths of the largest fish you have in the tank. If for example you only had tetras then you would not need to wait long before releasing the fry. It's just to stop them getting eaten. Congrats on the babies.

if you have good plant cover then you wold need a week at 82F at the most IMO.
i wold give em 2 weeks without plants.... my trap sank on day 2 of the last batch of fry i had and they all escaped. it dosnt look like any of teh fish are interested in them at all and its been 3 days. i wold have thought my dwarf/ perl guorami woldhave eaten any babie in sight but they left them alone.

I wait until they are about 1/2 inch. Of course, I have new fry that I never remove and they do fine. They are always in groups away from the bigger fish or they just hide. My females produce so fast and so many that I can't always remove the fry.

I usually wait until they are double in length and then add them. It usually takes about a month but when you realease them they grow much quicker anyway.

I am amazed how my glowlight tetras can ambush and suck down a fry...YEEKS. :crazy: I agree a half inch is about the size I'd use as safe from suckage, able to survive. In general in my large tank the tiny fry have many hiding places and any one of em stupid enough to wander around in open water kinda deserves it! Seriously, I often put fry that look healthy and interesting over in my male guppy tank to grow out abit. Those guppy guys are so busy showing off to each other(remember that walk-off in Zoolander?) they could care less about the tiny fry, besides they'd trip over their long fins trying to catch them and the fry are long gone. Mind you the second I can sex a fry and it's female it's outta there and into the big tank pronto. No point in tempting the guys! Not having guppy condoms, that's the safest route for me. :rolleyes:
