I had five of bluefins, one is mature female and the rest is too young but when they are mature. How to breed them? I had some sucessful breeding with Japanese medaka fish. Any tips?

I was thinking about getting a tub for them and one for fundulus species and one for gambusia this spring when the snow were thrawed from Minnesota winter if there were any snow this year.

I put 5 in a kiddie pool this spring. Now I have way too many to count. I really did nothing. I have also had them spawn in a tank with lots of plants and algae. No tricks.

Just curious, was the kiddie pool outside and/or covered with netting or anything? When I was a kid I had a 4'x4' rectangular kiddy pool, me and my buddy put a bunch of very small painted turtles and a few dozen feeder goldfish and a few dozen feeder guppies. After one night they were all gone, everything. Racoon tracks around the pool. Was amazed that they even got all the guppies, everylast one.

That easy? Wow! Can't wait for the summer. I'm not worry about raccoons (I have two dogs who live outdoors) through I'm more worried about unwanted bears but I don't think they wanted to chase some 1 inch long fish. What I should add to the tub beside the water and bluefins. Is it okay for put pygmy killifish, rainwater killifish and possible japanese ricefish with them? Just wondering.

Just like this, no cover or netting.

So I will just put some plants in the tubs? And maybe a net covered over the tub, prevent the "toe biters" and dragonfly larva from enter the tub.

But can I put pygmy, rainwater and Japanese medaka killies with bluefin killies or should I get another tub for them? What about foods during outdoors? I never had kept fish outside before.

For breeding, I would keep them all in seperate tubs, as to raise your production rate.

As for food, it will all naturally come to them. Mosquitoes will lay eggs and the water will soon be swarming with daphnia and other microscopic organisms, along with algae. Set it up and add plants and the substrate and let it sit outside for a couple weeks before adding them to the pond. You probably won't get any breeding until next spring, though.

Yes, lots of plants. Wash them first to prevent aquatice insects. You wont get them all, but can get most. I bathed my plants in a mild bleach solution first.

These bred fine with other killis with them. In fact outbred them 20 to 1. I fertilized the pool, to encourage plants, and seeded it with pond water, and Daphnia. The Daphnia were short lived. Once the fry started hatching, the Daphnia dwindled. Mosquito larvae were surely the primary live food.
