Update to this.

Judging by the date of my last post, it's been nearly 2 months since I let the fry go free. They're still not very big at all and have not developed full colour. They are roughly 3 months old I assume.

- I changed their diet a bit to put more of a stress on protein, but it doesn't seem to be working much.
- I changed the tank's environment to allow for more swim space (which they love)

Ideas? They're still small.

New females and new male(s) would introduce new genes and possibly larger fish assuming large female's and or male's were chosen
Many times the fishes offered are all from the same spawn and as such , they may or may not have the genes for growth desired.
If after this time growth was still slow or fishes were small,I would be looking for new breeding stock.

Indeed, I've done that. I recently bought 2 or 3 more platies to increase the gene pool and will soon be unloading 5 or 6 fry to a friend.

I never buy more than 2 platies from the same tank, and I usually buy them from a different store.

Is wise to do as you are doing.

I found that out a long time ago, Fry left with the adults grow bigger and better then the ones removed,
Mollies NEVER do good in separate small containers, especially birthing netting or traps, Alot of folks can't even get them to live in those things past a few weeks let alone longer, So I'm not surprised their smaller.. more surprised their still alive.

As for the growth hormone, I totally do not believe that,

We seem to harbor and cater to the weaker fish, trying to save everything, So we look to blame it's faults and troubles to everything but what it is, in the wild these weaker, stunted, smaller sickly fish would never have made it to adult hood let alone to reproduce, Fish are bred for the numbers not their hardiness, it's all about profit.

I use to try and save every fish no matter what, But all you do is keep bringing troubles on yourself,
I got really tired of it and started culling extremely heavily. here's a good article on this, it also states
Quote:
"Fish are kept incredibly overcrowded in ratios of up to 200 per 10 gallon, growing to very good size, shedding considerable doubt on the theories surrounding release of growth-inhibiting hormones in crowded conditions."

Try live foods...

I'm feeding some of my fry on BBS and they seem to be growing faster.

I will try live foods eventually.. my location isn't the best right now considering how far I need to go to get to a store.

I've been feeding the fry a lot more egg yolk lately and less veggie-based foods. I noticed a small growth spurt in the younger ones over the last few days. Maybe my luck has changed :)

I personally don't use breeding nets... I have a moderately planted tank. Mixture of java moss, java ferns, other and several other plants, ranging in size. About 1/4 of my plants float around as I allow them to attach to other objects and grow. I'm referring to my 110 gal tank right now. Nothing but Livebearers (guppies, mollies, platys, swordtails) and one pleco... and snails...

Anyways, Fry popping out all the time. I don't feel the need to save any fish that dies. It died for a reason. Just like older fish die for other reasons. I rarely have adult fish that die of anything but old age. Younger fish I don't keep track of them just because of the volume I see. I'm also constantly adding to the breeding pool and removing other males out of the stock. I cycle through males however keeping the females. Due to m/f ratio is usually 1:2, 1:3, and even 1:4 ratio's. I have a secondary tank Smaller size, that I keep males in, no females. This tank is to cycle through males back and forth or give them away to other people (usually I sell them).

I'm trying to create some hybrid fish species that are colorful and can reproduce within the new hybrid species. My 110gallon tank is a free for all. no limits no singling out. However I'll be starting another project to single out species to breed with other species. I'll be documenting this section in detail.



Anyways, my rule of thumb is breeding nets are used to keep males from females until another house can be found. I generally only used them in breeding betta's. Other than that keep it more natural with survival of the fittest.

I usually only rescue a few in the breeder net and let them go free once they're a bit big (2 weeks to a month). I feed them a lot during that time.

It's only a 25 gallon tank though. And yeah, I use a *lot* of java moss for cover which is why I get a lot of living fry.

I just wish I had a bit more room. I'm not getting as many offspring as I used to either. I probably need to unload a bunch and start being a bit more strict with the genetics ;)

As for bigger tanks, I started with 10's, then went to 15's. Lucked out and got a steal on a 55g full setup. 4 years later (this year) lucked out on 2 more 55's just tanks though. Then a week later a 110g. I own over 10 aquariums.

As for you, being strict about your genetics is important. But remember only in good fun. Don't stress over it, and only do it for the fun of it. You probably can talk with your LFS and say I'll give you 3 for 1. However most pet stores will only take platy's for example once they are about 1" in size.

I generally do this. I go to my LFS every so often with 50+ full grown adults. In exchange I get drift wood, more species of fish / males... etc... he orders specific breeds for me when I ask. This is helpful to me, however not all LFS will do this. But most will, as long as it's not a chain store such as Meijer, Walmart, Petsmart... etc.


I don't know your living conditions or how much extra room you have, or money for that matter. Depending where you live, check Craigslist for aquariums that are dirt cheap, full setups... like 10gallons... and raise some young in it to sell to the LFS. Depending you can make your money back off of it later. I don't pay for fish food or anything... ever... lol.
