I only put them in the fresh water for a couple of minutes if that and they were trying to climb out of the tote so off they went into the pond and ate a couple of hours later and the bigger new male is trying to strut his stuff, hanging all over the females. So interesting to me is their interaction smelling each other and rubbing and such. I am glad I decided to go with the rays. Today we had church at our house because our building isnt just ready yet and wouldnt you know I went to shut the light over the pond off and I shut the return pump off instead and it back fed out of the return pipe cause some dummy has'nt put a check valve yet and 100+ gallons all over the basement (unfinished) floor again but I needed a water change anyways and it didnt stop about 20 people coming down to take a look and do some touching.
