I personally prefer mosquito fish as feeders because unlike rosies they don't contain thiamiase enzyme which is has been connected to hole in the head disease. The only bad thing is my LFS doesn't carry mosquito fish all the time. Any tips on spawning rosies

I was unaware about the link to Hole in the Head Disease. Is it from the Rosy naturally or from bad keeping practices?

Not really any tips. Malse and females in a tank with some plants and substrate breed like crazy. I started with a dozen 2 years ago. I now keep 10 and give the fry away. Still end up with too many. Was thinking about freezing the fry into cubes kinda like bloodworms.

Apparently it's the rosies in general. If you go to the health forum there is a sticky about hole in the head disease. In the sticky there is a link that shows the species containing the enzyme thiamiase.
 
Sorry to possibly hijack this thread. I am currently buying 3 dozen rosies a week and they only last a couple days with my Green Sunfish and Bullheads. I have read that Rosies and fathead minnows are the same thing and the fatheads that I had grew to about 3 inches before they got eaten. One of them got the "horns" on its head so I know they were getting close to breeding. I have a spare 10g tank that I use for quarantine/treatment purposes. Would this be large enough to contain a breeding population of Rosies? I also have a 20L that has two rosies and a fresh water flounder in it. The rosies were supposed to be food but he hasn't taken them. maybe I could breed some in there too. I wouldn't care if the flounder ate some of the fry so long as there were enough to feed my other fish too.
 
Your 10g or 20 liter would be fine for some breeding. Sponge filter, small clay pot or two, little wood, and plants. They are fairly easy to breed
 
Thanks, That 20L was supposed to mean 20g long. Sorry for the confusion. I think I may put 6 more rosies in the 20 long this week and let them do their thing. The flounder doesn't take kindly to stuff sitting in his sand. Maybe I can stick something to the sides of the tank for brooding/housing. I have an OTB filter on the tank with a sponge on the pickup to keep the sand out of it. I think the bottom still has a couple holes in it that fry would get sucked into. I think I will cover those with hot glue and give it a go in that tank. If it works out maybe I will use the 10g as a grow out tank to keep the population in the 20 manageable.
 
I have gotten very few fish to eat convicts.

More than I have gotten to be eaten, have ended up just living, and growing up in the tanks I tried to feed them to.

Pretty funny, some of them got to two inches before I dropped them all off at petco.
