I put several F lineolatus out in a 30 gallon plastic tub late last
summer with some aquatic plants. Fed them occasonally with dry
feeds. They got lots of mosquitoes and other wild inverts. By fall
there were at least 15 fry in the tub. With an earlier start and a
little more effort to save fry, I bet you could crank out plenty of
them. The fry are easily harvested since they hug the surface and
have little reflective spots on them. Use a very fine mesh aquarium
net to pick them out. If I get to it, I want to try this with F
cingulatus and L ommata this year. I had a tub full of ommata out
last year, but they went out later and didn't seem to produce. I
brought them in when the water had dropped to about 40 F with no
apparent ill effects. The fish were fat and happy. They have
overwintered in an indoor aquarium.
