Babies in a Bucket?

So I just bought a new bucket to help with water changes. It's just about three gallons, and I was wondering if it could hold fish? I have a 10 gallon with two female platys, one of which has dropped about 12 fry. They are of differing ages, 3-5 months, and I was wondering if I could put the five 3 month olds into the bucket? I can put aeration in and gravel on the bottom, maybe a plant or two. With daily 30% to 50% water changes, would they be alright? It's really warm were I live, always over 75F and, with air conditioning, always under 90F.
The reason I want to is because I read that older fry being in the same tank as younger fry will stop the young ones from growing? The 3 month olds have stayed at 3/4 of an inch for quite a while, when my 5 month olds were already pressing an inch at the same age. Can I keep the babies in the bucket? At least until I can get rid of the older fry?

 

I don't know if it's true or not but if it is you can probably get around the problem by doing larger and more frequent water changes.

 

Alrighty then, they'll stay in the 10gal <--- Happy fishes

Also, do you think giving them to Petsmart is a good idea? My Petco is horrible, but the Petsmart looks alright. Yay or nay?

 

Hard to say! If you like them and they'll accept fish then maybe it's OK?

 

Do you think I could give them away on Craigslist? Would that be safe for them? The reason I really don't want to give them to a store is because who knows who'll get them next? And all stores are the same (At least those around here) so they'd give five of my little ones to an 8yr old to put in a bowl!
If I do give them away on Craigslist, tips for shipping?

 

I wouldn't give them away. Maybe charge $1 for them or something reasonable. You'll be cheaper than the pet store but they'll be more expensive than feeder goldfish.
