The Tfs have been in the pond since its first stocking in late Nov of 14. Also added cnbg and res at the same time. I added about 300 of the largest sized Tfs hoping for a spring spawn. I followed up with 10,000 tfs in the spring of 15 and did the same this past spring. On occasion I will find one 3" dead one floating on the surface and so it tells me they are still in the pond, how many are still there in the pond I am not sure. I also have some Tp for some Fa control and for lmb forage. And crawfish are added for a snack or two. I may add someday some prawns if I can find them in the same price range as the crawfish. And CC I had the Tp over winter in 3 10 gal aquariums for the experience.
